The emissions gap report: are the Copenhagen accord pledges sufficient to limit global warming to 2c or 1.5c

This publication aims to assess the following questions: are countries' pledges of action collectively consistent with and, if implemented, likely to achieve the 2C and 1.5C temperature goals If not, how big is the gap between emission levels consistent with these temperature goals and the emissions expected as a result of the pledges? In responding to these questions, we are confronted with a series of highly complex issues, which result from scientific and political factors.
