© OECD/IEA 2013Four measures to keep the 2 °C target alive National efforts in this decade need to buy time for an internationalagreement, expected to come into force in 2020 Measures to 2020 should meet key criteria: Significant near-term emissions reductions No harm to countries’ economic growth Reliance only on existing technologies and proven policies Significant national benefits other than climate change mitigation Our 4-for-2 °C Scenario proposes four measures that meet thesecriteria

© 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
