Emissions Gap Report 2021

November - December 2021

The heat is on in the 12th edition of an annual series that provides an overview of the difference between where greenhouse emissions are predicted to be in 2030 and where they should be to avert the worst impacts of climate change.

The Emissions Gap Report 2021 shows that new national climate pledges combined with other mitigation measures put the world on track for a global temperature rise of 2.7°C by the end of the century. That is well above the goals of the Paris Climate Agreement and would lead to catastrophic changes in the Earth’s climate. To keep global warming below 1.5°C this century, the aspirational goal of the Paris Agreement, the world needs to halve annual greenhouse gas emissions in the next eight years.

If implemented effectively, net-zero emissions pledges could limit warming to 2.2°C, closer to the well-below the 2°C Goal of the Paris Agreement. However, many national climate plans delay action until after 2030. The reduction of methane emissions from fossil fuel, waste and agriculture sectors could help close the emissions gap and reduce warming in the short term, the report finds.

Carbon markets could also help slash emissions. But that would only happen if rules are clearly defined and target actual reductions in emissions while being supported by arrangements to track progress and provide transparency.
