Emissions Gap Report 2021
United Nations Environment Programme
Abstract
This twelfth edition of the United Nations Environment Programme Emissions Gap Report comes during a year of constant reminders that climate change is not in the distant future. There is a fifty-fifty chance that global warming will exceed 1.5°C in the next two decades, and unless there are immediate, rapid and largescale reductions in GHG emissions, limiting warming to 1.5°C or even 2°C by the end of the century will be beyond reach. As in previous years, the 2021 Emissions Gap Report has been guided by an experienced steering committee and prepared by an international team of leading scientists, assessing all available information, including that published in the context of the IPCC reports, as well as in other recent scientific literature.
