The International Energy Agency has issued a report charting four climate-wise steps countries can take to make a difference in greenhouse-gas emissions by 2020:
- Targeted energy efficiency measures in buildings, industry and transport account for nearly half the emissions reduction in 2020, with the additional investment required being more than offset by reduced spending on fuel bills.
- Limiting the construction and use of the least-efficient coal-fired power plants delivers more than 20% of the emissions reduction and helps curb local air pollution. The share of power generation from renewables increases (from around 20% today to 27% in 2020), as does that from natural gas.
- Actions to halve expected methane (a potent greenhouse gas) releases into the atmosphere from the upstream oil and gas industry in 2020 provide 18% of the savings.
- Implementing a partial phase-out of fossil fuel consumption subsidies accounts for 12% of the reduction in emissions and supports efficiency efforts.

© OECD/IEA 2013Key messages Despite encouraging steps in some countries, global emissionskeep rising and the scientific evidence of climate change increases Early national action is required while negotiating towards aglobal deal in Paris in 2015 that then comes into force by 2020 Four measures can stop emissions growth by 2020 and keep the2°C target alive, without harming economic growth There is a need for parallel action to deploy critical low-carbontechnologies at scale after 2020, including CCS The energy sector must adapt to climate change, both in theresilience of its existing assets and in future investment decisions
