Enhanced Policy Scenarios for Major Emitting Countries

Analysis of current and planned climate policies, and selected enhanced mitigation measures

Published: 30/04/2015

This report provides an overview of projected greenhouse gas emissions in 13 major emitting countries/regions (Australia, Brazil, Canada, China, the European Union, India, Indonesia, Japan, Mexico, the Russian Federation, South Korea, Turkey, and the United States). Ecofys & NewClimate Institute, IIASA and PBL estimated the impact of current, planned and a selection of enhanced policies up to 2030. In 2010, these countries/regions were responsible for about 65% of global greenhouse gas emissions.

In all the countries/regions considered, significant further reductions are possible through a selection of policy enhancement measures that are in line with national priorities. By replicating ‘best-in-class’ policies or progressing to identified benchmarks, it is possible to significantly enhance current efforts so that all countries/regions considered here would achieve or overachieve their pledges by 2020.

Looking only at 13 major emitting countries/regions, the enhanced policy scenarios in this report could reduce emissions by 6.1 GtCO2e by 2030, compared to under current policies. By 2020, reductions of up to 2.3 GtCO2e below what can be expected from current policies would be possible.
