Bridging the Emissions Gap – A UNEP Synthesis Report

This technical document outlines how far the current commitments and pledges of developed and developing nations can take the world in terms of achieving the 2°C limit or less, and the gap that remains between ambition and reality. It first reviews and summarizes the latest scientific studies of the gap. It then tackles the  question – How can the gap be bridged? – by examining the question from different vantage points: from that of global integrated assessment models, from bottom-up studies of individual economic sectors, and from published work on the mitigation potential in international aviation and shipping emissions.
