Getting to the 2DS will rely heavily on energy efficiency and renewables initially, but all technologies play a role.

Different energy futures…
The 2DS will require energy conservation and also significant transformation of the global energy mix.

Short term action pays off: emissions can be kept on a 2C pathway to 2020
Energy sector decarbonisation actions are not solely driven by emissions goals
Power sector decarbonisation is particularly critical in the period 2020 to 2030
Action on investment and technology is needed now to set the conditions for long‐term energy sector transition
The energy sector needs to prepare for the impacts of climate change

Chapter 2:The new landscape of emissions

Current status of ETSs worldwide
© OECD/IEA 2014
Key issues include:
The challenges of implementing an ETS in energy systems of a more regulated nature
The need to understand and address the impact of carbon prices on electricity prices
The importance of incorporating policy flexibility to respond to external influences such as other energy and climate policies
Interaction between ETSs and the energy sector
© OECD/IEA 2014
Some conclusions from recent ETS experience
ETSs may be implemented in highly regulated electricity systems, though additional measures may be needed to ensure propagation of the carbon price signal.
Compensating those groups affected by rising electricity prices (driven by the carbon price) may achieve better outcomes than preventing the price rise.
Improved integration of ETSs and complementary energy policies can ensure each set of policies meets its their respective objectives.

© OECD/IEA 2014
Type I and Type III metrics for the electricity sector
To achieve the 2DS, the average emissions intensity of new generation must be lower than that of natural gas before 2020, and only 10% of today’s levels after 2020.

Japan has some of the cleanest and most efficient coal plants in the world, and most are installed with flue gas technologies for SO2 and NOx.
South Korea is gradually moving towards a more efficient power fleet by upgrading and replacing the existing plants with the new and more efficient ones.
China currently has the fastest installation rate of flue‐gas desulphurisation (FGD) and selective catalytic reduction (SCR) anywhere in the world.

Keep coal use below 65% of TPES by 2015
Cap coal consumption at 10 Mt by 2017 (a 13 Mt reduction)
Reduce power capacity by one‐third
Ban construction of new oil refining, steel, cement and thermal power plants
Reduce cement production by 50%
Upgrade 300 polluting firms in 2014
Regional measures: Beijing
© OECD/IEA 2014
China’s air pollution controls can lead to significant GHG reductions, provided that they are structured to achieve these dual objectives
Areas for consideration:
‐ Emissions shifting to unregulated/remote regions
‐ Ambitious syngas developments are significantly more energy‐ and carbon‐intensive
Continued improvement of air quality statistics, accounting, and enforcement measures will be needed
Some strategic considerations

GHG standards for new power plants
Uniform national standards for coal and gas
Coal units would need CCS; NGCC meets the standard already
GHG standards for existing power plants
State‐specific carbon intensity goals
Projected to reduce emissions by 30% in 2030 relative to 2005
Built around the application of four “building blocks”
Will allow use of market mechanisms such as cap‐and trade
Regulating GHGs from electric power plants
© OECD/IEA 2014
Some quick take‐aways from the U.S. GHG regulations
Standards for new power plants are likely to have little effect on US GHG emissions
By 2020, power sector emissions will already have declined 13% since 2005; thus, standards expected to reduce emissions an additional 17% over the following decade
In 2030, natural gas would be the dominant fuel (33%), but coal would still produce a significant share of electricity (31%)
CO2 intensity of US electricity generation projected to fall 19% from its 2012 fleet‐wide rate, i.e. to that of typical NGCC plant
Mobile source rules for new cars and trucks are also important and may yield more reductions by 2030
