The UN Environment Emissions Gap Report 2017 presents an assessment of current national mitigation efforts and the ambitions countries have presented in their Nationally Determined Contributions, which form the foundation of the Paris Agreement.
The emissions gap in 2020 is the difference between emission levels in 2020 consistent with meeting climate targets, and levels expected in that year if country pledges and commitments are met. As it becomes less and less likely that the emissions gap will be closed by 2020, the world will have to rely on more difficult, costlier and riskier means after 2020 of keeping global average temperature increase below 2°C. If the emissions gap is not closed, or significantly narrowed, by 2020, the door to many options limiting the temperature increase to 1.5°C at the end of this century will be closed.
This report shows that the estimated emissions gap in 2020 for a “likely” chance of staying below the 2°C target is large, but it is still technically possible to close this gap through concerted and rapid action.
There have been an increasing number of statements from some in the scientific community and other commentators that meeting the 2°C warming goal is now beyond reach.
