The emissions gap report : are the Copenhagen accord pledges sufficient to limit global warming to 2 degrees C or 1.5 degrees C? : a preliminary assessment

Abstract

The Copenhagen Accord declared that deep cuts in global emissions are required “so as to hold the increase in global temperature below 2 degrees Celsius”. The Accord called for an assessment that would consider strengthening the long-term goal including “temperature rises of 1.5 degrees”. Since December 2009, 140 countries1 have associated themselves with the Copenhagen Accord. Of these, 85 countries have pledged to reduce their emissions or constrain their growth up to 2020.
