- This publication aims to assess the following questions: are countries' pledges of action collectively consistent with and, if implemented, likely to achieve the 2°C and 1.5°C 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.
