Emission gap report 2020-21

The report was published by United Nations Environment Programme (UNEP). The report It informs that the 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.

Important points in report

• Following an unprecedented drop of 5.4 % in 2020, global carbon dioxide emissions are bouncing back to pre-COVID levels, and concentrations of GreenHouse Gases (GHGs) in the atmosphere continue to rise.
• New mitigation pledges for 2030 show some progress, but their aggregate effect on global emissions is insufficient.
• As a group, G20 members are not on track to achieve either their original or new 2030 pledges.
• The long-term net-zero emissions pledged by 50 countries, covering more than half of global emissions show large ambiguities.
• At the end of the century global warming is estimated at 2.7°C if all unconditional 2030 pledges are fully implemented and 2.6°C if all conditional pledges are also implemented.
• The current atmospheric carbon dioxide (CO2) concentrations are higher than at any time in the last two million years.
• From 2010 to 2019, GHG emissions grew by 1.3 % per year on average.
