Background to Research

• Peter Wyatt working paper 2011 – Workplace destination CO2 comparisons

• Carty Aherne 2011– Transport mode CO2 figures

• CSO POWCAR dataset 2006– Workplace destination data– 250 metre grid square granularity

• NTA/DIT collaboration

MethodologyGranularity

Corduff Park, Blanchardstown - outline of ED and aerial view outline

Aerial view of population at origin in linear interpolation and grid square formats respectively with outline of ED overlaid on images

MethodologyPOWCAR dataset and Granularity

Electoral District data 250m Origin and Destination Population data

MethodologyCarbon Emissions per Mode

The data presented here is from Carty & Aherne (2011) except for the CO2 emissions associated with lorry transport, which was located on the website of the University of Exeter (2003)

Mode Mode Label

CO2 Emissions

Walking 1 0

Bicycle 2 0

Bus 3 0.077

Rail 4 0.0152

Motorbike 5 0.0939

Car 6 0.169

Car (passenger) 7 0.0845

Lorry 8 2.68

Page 8: ITRN presentationV1

MethodologyThe Model and Model Formula

• Input: POWCAR dataset + Carbon Emissions per mode of transport

• Output: CO2 reading per person to each destination grid square in GDA

∑ Distance X CO2 per km X Count

Conclusions and Recommendations

• Progression from previous research is the calculation of CO2 emissions at destination

• What gives the results the extra rigour is – (a) the quality of the census data– (b) The 250m grid square i.e. the granularity

• Demonstrated link between carbon emissions, location and transport

Page 22: ITRN presentationV1

Conclusions and Recommendations

• Predictive tool can assist evidence based decision making

• The methodology can be utilised for the 2011 census data which will be available in POWCAR for the entire country

• Suggest incorporate BER and TEC in an overall Energy Performance Certificate
