The emissions gap report : Are the Copenhagen accord pledges sucient to limit global warming to 2° C or 1.5° C?
The emissions gap report : Are the Copenhagen accord pledges sucient to limit global warming to 2° C or 1.5° C? A preliminary assessment / Kelly Levin, Murray Ward. UNEP, 2012, 55 p.
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.(© UNEP)

Presentation (© UNEP) :
Climate change represents one of the greatest challenges but also an inordinate opportunity to catalyze a transition to a low-carbon, resource efficient Green Economy. This report informs governments and the wider community on how far a response to climate change has progressed over the past 12 months, and thus how far the world is on track to meet wider goals. The pledges associated with the Copenhagen Accord of 2009 are the point of departure for this report. What might be achieved in terms of limiting a global temperature rise to 2ºC or less in the 21st century and in terms of setting the stage for a Green Economy? And what remains to be done – what is the gap between scientific reality and the current level of ambition of nations?… more
