National Carbon Accounting System Technical Report iii

SUMMARYJaakko Pöyry Consulting has developed a

methodology for assessing the contribution that the

use and accumulation of wood products makes to

the size of the carbon pool. This methodology is

captured in a computer model which we have, for

the purposes of this report, called "A National

Carbon Accounting Model for Wood Products" or

"Carbon Model". The model operates under the

software package Microsoft® Excel 2000.

The Carbon Model uses available statistics on log

flows from the forests and estimates the carbon

content of the various wood products processed

(e.g. sawn timber, plywood, pulp and paper and

woodchips). Estimates of the decay period of each

class of wood product have been made and

methods proposed for estimating the existing and

future pool of carbon represented by wood products

proposed. The Intergovernmental Panel on Climate

Change (IPCC) has proposed four alternative

approaches for accounting for carbon in wood

products. The Carbon Model developed in this

study incorporates these approaches.

This report focuses more on methodologies rather

than outcomes. However, to demonstrate the kind

of output generated by the model, we have run the

model using starting data and assumptions, most of

which are considered to be reliable but some of

which will require further refinement.

The main sources of information were ABARE, State

Forest Services, Forest and Wood Products Research

and Development Corporation (FWPRDC), industry

associations, CSIRO, forestry companies and Jaakko

Pöyry Consulting’s own databanks.

With some minor improvements, these sources

provide an adequate base for ongoing data

collection for estimating carbon accumulations.

Priority areas for further research and development

include:

• Determining appropriate carbon content for

Australian species.

• Refining the lifespan of timber products,

both long term products such as framing

timber in housing and products with a

shorter lifespan such as paper and

packaging.

• Researching the final disposal methods

of wood products some of which

(e.g. landfills) may significantly extend

the life of products before carbon release.

• Refining the methodology for determining

the level of carbon sequestered in housing.

• Evaluating the effects of the different IPCC

accounting approaches on Australia’s

carbon balance and the implications of each

approach on both sustainable forest

management and Australia’s commitments

under the Kyoto protocol.

Nothing in the report is or should be relied upon as

a promise by Jaakko Pöyry Consulting (Asia-Pacific)

Pty Ltd as to the usage and life cycle of wood

products in Australia. Actual results may be

different from the opinion contained in this report,

as anticipated events may not occur as expected and

the variation may be significant.

1. BACKGROUND AND PROJECT DESCRIPTION

A National Carbon Accounting System is

being established within the Australian

Greenhouse Office. This project, "The Usage and

Life Cycle of Wood Products", is one of a series of

pilot projects commissioned to propose a

methodology for assessing the contribution that the

use and accumulation of wood products makes to

the change in and size of the carbon pool.

Jaakko Poyry Consulting has developed an Excel-

based model, which we have called a "National

Carbon Accounting Model for Wood Products in

Australia". Within this report we refer to this model

as the "Carbon Model". This model is supplied in

electronic form in Excel 2000. A hard copy version

is attached in Appendix 1.

Information has been obtained and examined under

the following components of the Carbon Model:

• Log Flow from the Forest: Current annual

production data were obtained by species

groupings, and product classes, i.e. sawlogs,

veneer logs, pulp logs, roundwood and

other, e.g. sleepers.

• Fibre Flow from Processing: Data on the

intake of raw materials to the various

processing options and the output of

products and by-products have been used

in the model to estimate the total tonnes of

carbon produced each year under various

end product classes.

• Life Cycles and the Wood Products Carbon

Pool: Estimates of the life cycles appropriate

for each class of wood product have been

made and, together with the historical data

on housing stock for example, methods for

estimating the existing pool of carbon,

as represented by wood products, have

been proposed.

2. LOG FLOW INFORMATION

Annual log removals data are available through the

Australian Forests Products Statistics published

quarterly by the Australian Bureau of Resource

Economics (ABARE). Data are also available

through the Levies Management Unit of the

Department of Agriculture, Fisheries and Forests, on

behalf of the Forest and Wood Products Research

and Development Corporation (FWPRDC). Log

removals data are also published by the relevant

State Forest Services and these provide a valuable

cross-check on ABARE data.

SOFTWOODTotal removals of all plantation softwood logs for

1997/98 are shown in Table 2-1. These data were

collated from the annual reports of the various State

Forest Services and from information provided by

the private softwood plantation owners. A total

(crown and private) of 6,488,300 m3 of saw and

veneer log was harvested in 1997/98 according to

these data. However, the corresponding FWPRDC

figure provided by the Levies Management Unit is

6,663,603 m3 while the provisional figure from

ABARE is 6,547,000 m3 (Table 48, March Quarter,

1999). The ABARE figure includes cypress pine.

The estimated volume for cypress pine logs cut in

1997-98 is 296,000 m3 (refer to Section 2.3).

Deducting this from the ABARE figure leaves a

net softwood figure of 6,251,000 m3.

For pulplogs, the ABARE figure is 3,678,000 m3

and for roundwood it is 340,000 m3. The close

comparisons between all of these data are an

indication that the ABARE, FWPRDC or State Forest

Services data for softwoods can be used with

reasonable confidence.

HARDWOOD

Total removals of all hardwood logs are shown in

Table 2-2 again using the annual reports of State

Forest Services as sources. Plantation-grown

hardwoods have been included in Table 2-2 along

with native hardwoods as the volume harvested is

still small and is mainly pulpwood.

The volume of hardwood logs from plantations will

increase rapidly over the next few years and should

be reported separately in the future.

In general, there is good agreement between the

various sources of information for hardwood

removals, in the saw and veneer log and pulp log

categories, as indicated below.

The FWPRDC figure would be expected to be low,

because mills processing less than 1,500 m3/a

do not pay a levy and are not required to file a

return. However, the comparisons between

ABARE and Table 2-3 data are quite good and

it is considered that the ABARE data for hardwood

saw and veneer logs and for pulp logs can be used

with confidence.

For "Poles, Sleepers and Other", however, the

information is conflicting, where available, and has

been otherwise difficult to uncover. As an interim

measure, it is suggested that the figure of 184,400 m3

(from Section 3.11.) be used as a constant. As poles

represent a considerable carbon store, it is

recommended that this area be investigated further.

CYPRESS PINECypress pine is a small component of the total log

removals accounting for approximately 295,700 m3

in 1997/98 according to State Forest Services annual

reports and private estimates.

Unfortunately, ABARE includes cypress pine

removals under the total for coniferous logs and a

separate figure is not provided. It is necessary to

extract cypress pine volume and analyse separate

from softwood sawmilling because:

• Cypress pine is a native conifer and

softwood sawmilling largely refers to exotic

species plantations, and

• Cypress pine is a denser wood than exotic

pines and is used by a totally separate

industry supplying different products to the

market.

A cypress pine figure can be developed from the

ABARE information by applying a conversion factor

to sawnwood consumption and applying a

conversion factor to convert back to equivalent log

removals. It is recommended that ABARE takes

steps to provide a separate entry for cypress pine

sawlog removals. A figure of 315,000 m3 sourced

from the FWPRDC has been used in the model.

This is close to the figure in Table 2-3 indicating

FWPRDC data is likely to be reliable.

BARKThere has been no accounting for bark in this study

and it is proposed that all bark should be regarded

as being a component of logging slash (harvesting

residue) and accounted for under logging

operations, for the following reasons:

• Logs are sold and log volumes are

recorded on an underbark basis.

• In most hardwood operations,

logs are debarked in the field.

• In softwood operations, it is estimated

that up to 50% of bark is lost prior to

the logs reaching the mill. Most of this

loss occurs during the mechanised

delimbing and log docking operations.

• Most softwood bark recovered at the

mill is used for garden mulch which

it is considered, would have decay

characteristics similar to that of

logging slash.

Softwood bark is a significant source of carbon with

total bark varying from about 35% of underbark log

volume (not oven dry weight) in Caribbean pine to

20% in radiata pine and hoop pine. Also the carbon

content in bark is higher than in wood because of a

higher presence of flavinoids in bark. It is likely

that, in the future, an increasing proportion of

softwood bark will be used in the co-generation of

energy and it may be reasonable to review this

proposal should the situation change. In the

meantime, it is recommended that the characteristics

of bark such as moisture content, oven dry weight

and carbon content per m3 of bark on the standing

tree, etc, be investigated. This would be useful in the

event that more bark is used for co-generation,

particularly for radiata pine.

While this approach is appropriate at a continental

scale for accounting for wood product alone, and

a general assumption cannot be applied when

calculating a stand-based carbon balance.

Proportions of bark removal for the site may have

a significant impact on stand carbon balance.

3. WOOD FLOWS FROM PROCESSING

Wood flows in the various wood products produced

in Australia have been developed under the

following species/industry headings:

• Softwood sawmilling

• Hardwood sawmilling

• Cypress sawmilling

• Plywood

• Particleboard and medium

density fibreboard (MDF)

• Pulp and paper

• Preservative treated softwood

• Hardboard

• Hardwood poles, sleepers

and miscellaneous

• Export of woodchips and logs.

WOOD FLOW AND THE NATIONAL CARBON ACCOUNTING MODEL FOR WOOD PRODUCTSThe Carbon Model develops wood flows separately

for each sector and these are integrated to account

for cross-linkages. This is particularly important in

the accounting for waste or by-products which are

themselves used as resources for other segments of

the industry.

In conjunction with the carbon pool and life cycle of

timber products, this model enables the total and

future carbon pools to be estimated.

In broad terms, the components of the models

developed for each sector are similar, using:

• An estimate of raw materials input,

whether of sawlogs, woodchips ex-sawmill,

or pulp logs

• An estimate of the products of processing,

e.g. "x"% sawdust, shavings or sander dust

for on site energy generation or compost,

Australian Greenhouse Office4

Page 13: Usage and Life Cycle of Wood Products - NCAS Technical ......Figure 7-1: Impact of different wood products’ accounting methodologies in New Zealand over the commitment period 2008-2012

"y"% woodchips for other manufacturing

processes, "z"% of sawn timber products,

panel products, paper, etc.

• An estimate of the proportion of products

by product categories, depending on

whether their expected end-use is long term

or short term; e.g. framing timber, dry

dressed boards, cases and pallet stock,

panel products for use in house

construction, panelboards for use in

furniture and cabinets, newsprint paper,

writing and printing paper, etc.

• A final figure for total Australian

consumption by end use categories,

converted to wood fibre content (oven-dry

weight) and to tonnes of carbon.

• Import and export data were obtained from

the ABARE reports by end use categories.

FIBRE CONTENT OF WOODWood fibre content and carbon content are two

issues common to all of the processing options and

the choice of values adopted has a significant

bearing on the final outcome.

In the case of all sawn timber, treated softwood and

hardwood poles, etc., weighted basic densities for

the species involved have been applied across each

category. Basic density is defined as oven dry

weight divided by green volume and the values

adopted have been based on the CSIRO Division of

Forest Products, Technological Paper No. 13, 1961,

"Shrinkage and Density of Australian and Other

Woods". Shrinkage data were also obtained from

Technological Paper No. 13. For board products and

paper, however, the situation is different because

all have been subjected to varying amounts

of compression during manufacture and to

compensate for this, their basic densities have

been adjusted accordingly from the air dry density

of the finished products.

It is recommended that refinements to basic density

be made by undertaking more accurate species

weighting and by reviewing some of the CSIRO

data published in 1961.

Carbon content is defined variably throughout the

literature with values ranging from 0.4 to 0.53 of the

oven dry (bone dry) weight. A figure of 0.5 has been

adopted as a starting point to use in the model but

is able to be rapidly changed if needed. This issue is

discussed in more detail in Section 4.

Apart from the assumptions concerning basic

density and carbon content, the other

manufacturing assumptions were developed from

interviews with representatives from the various

industry associations and individual sawmilling

companies. The issues addressed included:

• recoveries of green sawn timber, sawdust

and chip;

• actual sawn sizes and corresponding

dressed sizes; and

• the range and proportions of products

produced.

For the softwood sawmilling industry, for example,

weighted averages of the information received have

provided assumptions of quite acceptable quality.

The same applies to the other species/industry

sectors, with the exception of hardwood sawmilling.

SOFTWOOD SAWMILLING

BackgroundThe softwood sawmilling industry in Australia is

largely based on plantations of exotic pines,

although the native pine, hoop pine, is grown in

southern Queensland. Most plantations were

initiated around the 1930’s. Early development was

slow, but momentum was gained in the 60’s and

70’s and the total plantation area is now 948,000 ha.

Softwood processing has matured over recent years

to become a very efficient, highly mechanised and

well integrated industry, comparable with any of its

overseas counterparts. Growth of the industry will

occur as the plantations mature, although further

growth of the softwood plantation estate is expected

to be relatively small, reflecting a current preference

by plantation growers to invest in shorter rotation

hardwood species.

Most softwood mills are large, with up to 500,000

m3/a log intake. Most of the sawn timber is

seasoned and dressed. Value-adding options such as

machine stress grading, glue lamination and finger

jointing are common.

Nearly all softwood mills are now operating on zero

waste, with all slabs and edgings being chipped for

paper pulp or panelboard feedstock and the

sawdust and shavings being used for boiler fuel to

provide energy for kiln drying. In some cases, some

of this material is sold for composting, but this is

unlikely to continue if the co-generation of

electricity becomes more financially attractive.

HARDWOOD SAWMILLING

BackgroundThe hardwood sawmilling sector is quite different

from the softwood sector being characterised by a

large number of small mills; even the very few large

hardwood mills are much smaller than the average

softwood mill.

In recent years, the hardwood industry has

undergone considerable change in response to

reductions in their traditional resource base and to

the impact that softwood framing has had on the

traditional green hardwood framing market.

As indicated earlier, the hardwood plantation

resource is expanding and removals from hardwood

plantations have been included in the total

hardwood removals. The current area of hardwood

plantations is 287,000 ha and is expected to grow by

70,000 ha in 1999/2000. Most of this material is

currently of pulp log quality, but more sawlogs will

be harvested as the resource matures.

There is a reasonable degree of integration in the

hardwood industry, however integration is difficult

for the smaller more remote mills.

The hardwood sawmilling industry is far more

complex and varied than any of the other sectors.

There are at least 10 major species throughout the

country, all having different densities and shrinkage

rates, and to a great extent having different end

uses. This sector has not been addressed in this pilot

study in nearly the same detail as was applied to the

softwood sawmilling sector and the outcome should

be regarded as indicative only. It is recommended

that further work be done on hardwood sawmilling

and that the possibility of splitting it into

regions/species groups be considered.

Information sources and assumptions used in the Carbon Model

Other Information SourcesAssumptions on the product out-turn from

hardwood sawmilling have been sourced from the

Victorian Association of Forest Industries and a

large sawmilling company operating mills in

Queensland, NSW and Tasmania.

Sawlog volumes produced and import/export data

have been sourced from ABARE.

Basic density of hardwoodA basic density of 630 kg/m3 is assumed for

hardwood sawlogs. This is an average of the

following ten commonly logged hardwoods: spotted

gum (E. maculata), blackbutt (E. pilularis),

rose gum (E. grandis), jarrah (E. marginata), karri

(E. diversicolor), mountain ash (E. regnans), alpine ash

(E. delegatensis), silvertop (E. sieberi), brown barrel

(E. fastigata) and messmate stringybark (E. obliqua).

The basic density assumed for poles and sleepers is

790 kg/m3. This is an average of spotted gum,

ironbark and blackbutt - the main species used.

Hardwood chips are lower in average density than

either sawlogs or poles and sleepers as they contain

a wider range of species as well as younger

regrowth and plantation material. An average basic

density of 570 kg/m3 is assumed. This is sourced

from Chin (pers. comm.) of CSIRO.

Other Information SourcesAssumptions on the product out-turn from

hardwood sawmilling have been sourced from the

Victorian Association of Forest Industries and a

large sawmilling company operating mills in

Queensland, NSW and Tasmania.

Sawlog volumes produced and import/export data

have been sourced from ABARE.

CYPRESS SAWMILLINGThe cypress sawmilling industry is restricted to the

native cypress pine forests in Queensland and New

South Wales. The quantity of logs removed is small

and the data are currently included in the coniferous

forest information in the ABARE quarterly reports.

Data from industry sources and from the annual

reports of the Forest Services of Queensland and

New South Wales indicate that log removals in

1997/98 were approximately 296,000 m3.

The industry consists of several relatively small,

low technology mills operating on a scattered

resource. Because of the distances involved,

integration with other processing sectors is difficult,

however some cypress pine chips are being used

in panelboard manufacture.

The products are principally green framing and

high value flooring and dressed panelling.

PLYWOOD (SOFTWOOD AND HARDWOOD)AND VENEERThe Australian plywood industry is based

principally on plantation grown softwoods and

about 8% hardwoods, both native and plantation

grown. Large, high quality logs, for which premium

prices are paid, are preferred.

In volume terms, the plywood industry is small,

but it uses high technology and produces a variety

of products. Total production in 1998 was only

170,000 m3 (ABARE).

In addition to plywood veneer, sliced or rotary

peeled decorative veneer is produced in small

quantities for furniture, door and panel overlays.

This production is not recorded separately by

ABARE (we recommend it should be). Jaakko Pöyry

Consulting estimates annual production is less than

10,000 m3.

Data sources used in the model for plywood

were from ABARE and the Plywood Association

of Australia. These data sources are considered

to be reliable.

PARTICLEBOARD AND MEDIUM DENSITYFIBREBOARD (MDF)The characteristics of these two wood panelboards

are different, but their feedstock and end use

product categories are similar. Their densities are,

however, different.

Particleboard and MDF plants are large-scale

operations and they are usually located close to their

resource. Both require low cost material as input

using either small logs unsuited to sawmilling, or

woodchips produced as a by-product of sawmilling.

Most of the feedstock is from softwood plantations,

although some regrowth hardwood is being used in

a plant in Tasmania and some cypress pine is being

used in a plant in Queensland. Total production in

1998 was 501,000 m3 MDF and 882,000 m3 of

particleboard (ABARE).

In terms of trade, Australia is a net exporter of

particleboard and MDF.

The industry source used for information on

processing assumptions in the Carbon Model was

the Australian Wood Panels Association.

Data reliability is considered to be high.

PULP AND PAPERPulp and paper plants are very large-scale

industries requiring large volumes of low cost

resource. Plantation grown softwood fibre provides

the major resource but hardwood and recycled fibre

is also important. Accounting for this sector is

complicated by the fact that recycled fibre is

exported and pulp is imported.

Australian Greenhouse Office14

Page 23: Usage and Life Cycle of Wood Products - NCAS Technical ......Figure 7-1: Impact of different wood products’ accounting methodologies in New Zealand over the commitment period 2008-2012

While ABARE data provides some useful

information, the Pulp and Paper Manufacturers

Federation of Australia (PPMFA) provide a more

detailed source of information.

Data are published by the PPMFA on their web site

www.ppmfa.com.au; data are available back to

1981/82. In fact, ABARE uses the PPMFA as

a data source and the reported production figures

are identical.

Production figures in the Carbon Model in this

study are derived from assumed raw material usage

and conversion figures rather than reported

industry figures. This is important for modelling

wood flows through the product cycle and is

consistent with the approach used in the model for

other industry sectors, apart from export woodchips

which uses ABARE statistics for export quantities in

bone dry tonnes.

The model-derived paper production estimates are

15% lower than the ABARE or PPMFA figures.

The reason for this is that the model calculates the

wood-only raw material requirements for pulp and

paper in "oven dry tonnes" while pulp reported

figures are in "air dry tonnes" which contain

approximately 10% moisture and 2-25% of non-

wood fillers depending on the process.

A complicating factor in the assumptions on waste

with the pulp and paper stream is the fact that mills

vary dramatically in their recovery according to

type. Kraft pulp mills typically have a low yield of

fibre (∼ 50%) whereas thermo-mechanical mills have

a high yield (∼ 95%). Based on weighted inputs,

a yield of 70% has been adopted.

PRESERVATIVE TREATED SOFTWOODBoth hardwood and softwood can be preservative

treated, but only softwood has been allocated a

separate category in this project. This is because

treated sawn softwood has some use categories

which are different to untreated softwood, whereas

hardwood is usually treated so that the sapwood

can be protected against borer attack and its use is

then the same as for untreated hardwood.

Treated softwood poles and posts have also been

included with sawn softwood, but treated hardwood

poles and piles have been included with sleepers

and other miscellaneous hardwood products.

The ABARE statistics do not list treated timber of

any description. The information used in the model

has been obtained from the Timber Preservers

Association of Australia.

HARDBOARDThe hardboard industry in Australia is quite small,

with only two plants in operation. One is at Ipswich

(Queensland) and the other is at Raymond Terrace

(NSW). Hardwood is used for feedstock, sourced

from pulp logs and sawmill residue. Total

production in 1998 was approximately 69,000 m3

(Jaakko Pöyry Consulting estimate).

The technology is quite old, but the products are

unique and have niche markets that are likely to

endure the competition from other panel products.

Both hardboard producers were contacted during

the study for manufacturing assumptions.

HARDWOOD POLES, SLEEPERS AND MISCELLANEOUSThe existing stock of hardwood transmission poles

in Australia is reputed to number about 6,000,000

and production is estimated to be about 100,000

poles per annum, equivalent to about 75,000 m3

of log.

Railway sleepers also represent a considerable

resource, and although concrete sleepers are now

used for all new work, timber sleepers will continue

to be used for the maintenance of secondary lines.

Miscellaneous includes a range of products such as

mining, fencing and landscaping timbers.

As mentioned in Section 2.2, the log removals

information for this group is conflicting and difficult

to uncover. A provisional constant of 184,400 m3 has

been proposed for use in the model (see Table 2-2)

and further work is recommended.

LOG AND WOODCHIP EXPORTS

Woodchip ExportsExport woodchips constitute a significant

proportion of the annual harvest from Australian

forests. The ABARE quarterly forest products

statistics gives 1,044,700 bone dry tonnes (BDt) of

softwood chips and 3,269,900 BDt of hardwood

chips exported in 1997/98. The total, 4,314,600 BDt,

is equivalent to 216 million tonnes of carbon (using

a conversion of 50%).

The Carbon Model uses the ABARE reported export

figures directly in bone dry tonnes. However, the

export controls have now been lifted on woodchips

and it may be difficult for ABS to get reliable data in

the future. Individual chip export companies keep

details of green tonnes exported and they have a

conversion factor to give tonnes of bone dry fibre

for the various species involved. These data could

be obtained on an annual basis, either from

individual companies or through the NAFI

woodchip exporters group.

Log ExportsTotal exports of coniferous logs for 1997/98consisted of 330,000 m3 of sawlog and 36,000 m3 ofpulp log. Hardwood log exports were 2,700 m3."Other" log exports came to 21,900 m3 (ABARE).

The log export trade is a relatively small part ofAustralia’s forest products trade. It is, howeverlikely to increase as the "Asian crisis" stabilises andmore ports are utilised.

4. CARBON CONTENT OF PRODUCTS

In the literature cited, carbon content varied between

0.4 to 0.53 of the oven dry (bone dry) weight.

The following is taken from Appendix II, "Costs of

Carbon Sequestration through Afforestation:

Greenhouse Gas Emissions Australian Transport"

Working Paper 23, Bureau of Transport and

Communications Economics:

Various factors are used to convert biomass and woodto elemental carbon.

Turner (1990, p. 2) divides the weight of wood by1.74. This is equivalent to wood being 44% carbon.

Barson and Gifford (1989a, p. 437) assume thatcarbon comprises 50% of dry biomass as do Griersonet al (1991a, p. 250).

On the basis that most organic matter in wood fitsthe formula CnH2nOn, Boardman (pers. comm.,October 1995) suggests that 40% wood biomass iscarbon.

McLaren and Wakelin (1991) note that variousstudies have used conversion figures for oven dryweight to weight of elemental carbon of 42% to 53%.They conclude that 49.6% is an appropriate figure forradiata pine in New Zealand.

In another study undertaken in the UK (Thompson

and Matthews, 1989), 42% is used for softwoods and

45% for hardwood, however none of these

references show how the values used were derived.

A conversion of 0.5 is used in the Greenhouse

Challenge Vegetation Sinks Workbook 1998.

Hillis (pers. comm.), from CSIRO, has provided the

same advice as Boardman. He makes the point that

the cellulose in wood is very similar in structure to

glucose, the formula for which is C6H12O6 and that

based on atomic weights, there is 40% by mass of

carbon in cellulose. Hemicellulose and lignin, the

other two principal components of wood, vary in

structure from cellulose, but they still have C, H

and O in about the same proportions and the same

applies to the relatively minor amounts of starch,

resins and other extractives that are present in wood.

Hillis further advises however, that the carbon

content of bark is often quite different and that in

radiata pine, the proportion of flavinoids is about

35% of the total composition. Flavinoids are high in

carbon (C15H11O6) and have 80% carbon by weight.

This would give a total carbon content of radiata

pine bark of approximately 54%.

In the Carbon Model a figure of 50% carbon by

weight of oven dry wood has been used as a default

but may be readily changed as required. This figure

is consistent with that used in the Greenhouse

Challenge Vegetation Sinks Workbook 1998, but

given the wide range of carbon contents quoted in

the literature, it is recommended that further

investigations of this issue be undertaken.

5. LIFE SPAN OF TIMBER PRODUCTS

The life span of timber products are critical in

ascertaining the quantity of carbon stored in timber

products. The Land Use Change and Forestry

Workbook 4.2 identifies four pools:

• short term (decaying in the year of harvest)- paper, etc;

• short medium term (decaying over 10years) - panel products, e.g. fibreboard;

• medium long term (decaying over 25 years)sawn timber, e.g. packing crates, furniture;and

• long term (decaying over 50 years) -building construction and fence posts.

In the Supplement to the Workbook (1998), the short

term pool decay rate was changed to three years.

In this study, considerable attention has been givento subdividing the various timber products poolsinto different classes and the life spans assignedvary from those in the workbook. Decay rates usedassume a constant decay over the lifespan.

National Carbon Accounting System Technical Report 17

Page 26: Usage and Life Cycle of Wood Products - NCAS Technical ......Figure 7-1: Impact of different wood products’ accounting methodologies in New Zealand over the commitment period 2008-2012

The assumption of constant decay may not be validand requires further investigation.

HOUSING SECTORThe housing sector in Australia constitutes the most

significant long term pool of carbon derived from

wood products and, at this stage, a life cycle of 90

years is being nominated for Australian housing for

the following reasons:

• Most of Australia’s housing is well in excess

of 50 years old.

• 50 years is the figure used by engineers

as the minimum life of housing for design

purposes and clearly almost all housing

exists for much longer than this.

• Houses are demolished for purposes of site

redevelopment and road construction and

there is also an attrition due to cyclones,

fires etc.

• 90 years is nominated as an interim

measure but more detailed investigation

is recommended.

LIFE SPAN POOLS ASSUMED FORMODELLING IN THIS STUDY

house construction and are therefore regarded as

having a life cycle of 90 years:

DISCUSSIONThe lifetime in use and the final disposal methods of

wood products are the areas of greatest potential

inaccuracy and where we would recommend to the

AGO that more investigation be done. Large

proportions of the products can survive in a landfill,

for example, for very long periods (Skog &

Nicholson, 1998).

Jaakko Pöyry Consulting has made preliminary

estimates of average lifetime in use for paper and

paperboard products:

Tissue 3 months

Newsprint 1 month (with eventual disposal

landfill where average life may

be 30 years)

Packaging 15 months (with eventual disposal

landfill where average life may

be 30 years)

Printing 3 years (with eventual disposal

and Writing landfill where average life may

be 30 years)

There is also the factor of recycling which extends

the time between cutting down the tree and eventual

disposal to landfill, etc. As a starting point, Jaakko

Pöyry Consulting assumes fibre in packaging and

newsprint grades is recycled 5 times; printing and

writing papers twice and tissue zero. For packaging

grades, which are largely recycled fibre, the effective

lifetime is 6 x 15 months = 7.5 years.

As can be seen, these factors have a greater weight

than the actual initial lifetime of paper and

packaging products in determining carbon emissions.

Jaakko Pöyry Consulting’s Carbon Model treats all

short life products such as paper and paper

products as decaying within 3 years with

consequent C emissions to the atmosphere.

In fact, the effects of disposal methods in landfills

and recycling could significantly prolong the period

of carbon sequestration.

This area needs more investigation and is

recommended for additional study by the AGO.

6. POOL OF WOOD PRODUCTS IN SERVICE

HOUSINGThe number of houses, as well as their longevity, is

required to calculate the major pool of solid wood.

The total number of private dwellings in Australia

at the time of the 1996 census was 7,019,300 of

which 5,366,500 (76%) were separate houses and a

further 574,100 (8.2%) were either semi-detached,

townhouses, row or terrace houses (see Table 6-1.).

Unfortunately the categories for recording private

dwellings have been subject to minor changes over

the years, with the most recent change being in

1991. Nonetheless, "Total Private Houses" has been

recorded for every census back to 1911 when the

number of private dwellings was 928,862.

Factors not included in the census however are that

the average floor area of houses increased by about

19% between 1982 and 1997 (BIS Shrapnel – Sawn

Timber in Australia, 1996-2011) and that there has

been an increase in house renovations and extensions.

"Year Book Australia 1995" mentions that 67% of

houses approved in 1992/93 used brick veneer

cladding and 7% used timber cladding. Brick veneer

is most popular in the ACT with 97% of approvals.

It is least popular in Western Australia, the

Northern Territory and parts of northern

Queensland where the roof frame is generally of

timber, but the walls are usually cavity brick or

concrete block.

Some brick veneer houses use steel framing,

although nationally the use of timber framing for

brick veneer, fibreboard and timber clad houses is

quite high at around 95%.

The number of new separate houses built over the

30 year period 1968/69 to 1997/98 was 3,063,593.

This is an average of 102,119 per year.

The timber volume used in a 2-storey brick veneer

house of 180 m2 total floor area, with the lower floor

of concrete slab and the upper of timber, has been

calculated at 13.88 m3. Timber cladding on the upper

storey would add 3.1 m3. (Source: D.M. Greve and

W.I. Diehm, "Timber volumes used in house

construction", Queensland Department of Forestry,

Timber Trends No. 2, 1985.)

MODELLING APPROACH TO CARBONSEQUESTRATION IN HOUSINGThere are a number of possible methods for

modelling how much carbon is sequestered in

existing houses and the rate at which this will be

released. The approach adopted in the Carbon

Model has been to:

Australian Greenhouse Office20

Figure 6-1: Australian housing starts (1955-98)

Source: Australian Bureau of Statistics

Page 29: Usage and Life Cycle of Wood Products - NCAS Technical ......Figure 7-1: Impact of different wood products’ accounting methodologies in New Zealand over the commitment period 2008-2012

• Use historical data on new house construction

(housing starts) as a base (actual data 1955-

1987 assumed housing starts pre-1955).

• Assume an average wood content per house.

This figure can be adjusted at any year in the

model to allow for changes in building sizes,

styles and wood content.

As a starting point, we have assumed a wood

consumption of 15 m3/house in the early

1900’s reducing to 13 m3/house currently.

Note, the 15 m3/house is an estimate and is

not based on research.

• Convert the total wood content to a carbon

equivalent. A basic density reduction from an

average of 600 kg/m3 in the early 1900’s to

450 kg/m3 has been used for timber in

houses. A carbon equivalent of 50% has been

assumed.

• Assume a constant decay rate over 90

years, i.e. 1.11% of the carbon content is

lost each year.

Using this methodology, the starting values (1997)

for accumulated carbon in the existing carbon pool,

carbon was estimated as 15.8 million tonnes.

Aspects of this approach, which will require further

research and development include:

• Available data on housing starts go back to

1955; What was the level of new housing

preceding this?

• What is the level of wood in new dwellings

and how has this changed over time?

• Is a constant annual decay rate over 90

years realistic for housing or is some other

relationship more appropriate?

CARBON STARTING LEVELS IN OTHER POOLSThe suggested approach to estimating carbon

starting levels for products with shorter life spans

than timber in housing is to:

• Use historical production and import data

for each of the main product types, e.g.

plywood, MDF, paper and paper products.

• Convert this to carbon equivalents.

• Apply a decay rate based on the assumed

product life or pool.

This is a recommended follow-up activity.

As a starting point (1997) for the Carbon Model,

Jaakko Pöyry Consulting have assumed starting

values for the carbon pools (other than housing),

based on preliminary trend estimates. The start

point for the Carbon Model are shown in Table 6-2.

7. CARBON ACCOUNTING METHODS ANDIMPLICATIONS ON CARBON POOL

An expert group from the Intergovernmental Panel on

Climate Change met in Dakar1 in May 1998 to evaluate

approaches for estimating net emissions of CO2 from

forest harvesting and wood products. In their Dakar

report , four approaches were evaluated:

• The current IPCC default approach. - All

CO2 emissions and removals associated

with forest harvesting and the oxidation

of wood products are accounted for by the

country in which the wood was grown and

in the year of harvesting.

• The stock-change approach. - Changes in

carbon stock in forests are accounted for in

the country in which the wood is grown,

referred to as the producing country.

Changes in the products pool are accounted

for in the country where the products are

used, referred to as the consuming country.

• The production approach. - Stock changes

derived from forests are accounted for in

the producing country. The carbon

contained in exported wood products

remains accounted for in the carbon stock

of the producing country.

• The atmospheric-flow approach. - Removalsof carbon from the atmosphere due to forestgrowth is accounted for in the producingcountry, while emissions of carbon to theatmosphere from oxidation of harvestedwood products are accounted for in theconsuming country.

Jaakko Pöyry Consulting has included the capacityto model carbon sequestered by the IPCC default,stock change and production approach into theNational Carbon Accounting Model for WoodProducts. The atmospheric flow approach has notbeen attempted due to its complexity andconceptual difficulty. The results of theseapproaches contained in the model should beregarded as preliminary. Jaakko Pöyry Consultingprovides this capacity purely so the user canexperiment with the affects of the differentapproaches. The interpretation of the differentapproaches is our own.

IMPLICATIONS OF DIFFERENT APPROACHESA paper by Ford-Robertson, Robertson and Sligh inAppita 1999 – "Implications of Carbon AccountingMethods for Harvested Wood Products in NewZealand" found that the different accountingmethods under review by the IPCC had profoundlydifferent effects on New Zealand’s carbon balanceduring the commitment period 2008-2012 under theKyoto Protocol (refer to Figure 7-1.)

Implications of carbon accounting methods for harvested wood products in New Zealand. Appita ’99, pp 681-688.

The impact of applying the three approaches

using model developed in this study is shown

in the following figures. These assume production

remains constant at 1998 levels over the next 10

year period. All assumptions in regard to

manufacturing also remain the same.

It is emphasised that the Model’s outputs are

indicative as they are based on, as yet, only crude

estimates of the accumulated carbon pool to date.

Importantly, however, the Model provides a

mechanism by which Australia’s carbon stocks can be

determined using different accounting approaches.

An important follow-up to this study will be the

refinement of the Model to study the impact on

Australia of the different approaches over the first

commitment period 2008-2012.

8. SUMMARY OF RECOMMENDATIONS FOR ONGOING DATA COLLECTION

AND FUTURE RESEARCH

IMPROVE DATA ON HARDWOOD• Hardwood logs from plantations should

be reported separately in ABARE.

• ABARE data on hardwood poles and

sleepers is unreliable. Producers should be

approached to improve data reliability.

• Hardwood sawmilling input data for the

Carbon Model could be disaggregated into

3 regions to improve its precision.

The suggested regions are:

1. Western Australia

2. Queensland and

Northern New South Wales

3. Tasmania, Victoria

SOFTWOODS• ABARE appears to be a reliable source for

ongoing data collection.

• Cypress sawlog harvest data should,

however, be reported separately by ABARE.

At present, these data appear to be included

along with other softwoods.

BARKBark has not been accounted for in the model.

A better understanding of the carbon content of

bark and its destination and use after harvesting is

needed to account for this significant carbon source.

WOOD PROPERTIES• The average basic densities used in the

model need to be reviewed. More accurate

species weighting may need to be applied,

particularly for hardwoods where a large

range of species with an equally large range

in density are utilised.

• Further research into the carbon content of

the species used in Australia is needed.

This is fundamental to any evaluation of

carbon sequestration in wood products.

Although there are considerable references

already on this subject, there is enough

confusion over the wide range of carbon

contents reported to make an objective

selection of the most appropriate carbon

content difficult. The model uses 50%

carbon by dry weight as a default starting

point for all products but may be readily

changed. This is simplistic and needs to

be refined to provide greater precision in

determining carbon estimates.

LIFE SPAN OF TIMBER PRODUCTS• A provisional life span of 90 years for wood

in houses is proposed. This is not based

on detailed research. More work is needed

to refine/verify the figure for carbon

modelling purposes.

• Similarly, the effective life span of other

products, especially paper and packaging,

which are often recycled should be more

thoroughly researched.

• The final disposal method of wood products

consumed in Australia is not well

researched. How much wastepaper,

for example, is disposed of in landfill

sites which are reported to be effective

carbon sinks?

• Confirmation of the carbon sequestration

effects of landfill sites is needed in Australia.

ACCOUNTING APPROACHES FOR CARBON IN WOOD PRODUCTSThe IPCC are reviewing four different approaches to

carbon accounting. Which approach is adopted can

significantly affect carbon balances at the national

level and has implications for data gathering and

reporting. More detailed modelling of the various

approaches for Australian wood production should

be a high priority leading up to the first

commitment period from 2008-2012.
