Greenhouse gas emissions need to decrease substantially to limit global average temperature to a maximum of 2°C warming above the preindustrial level in 2100. Emerging economies are of increasing importance in this global effort. This report assesses how ambitious emission reduction pledges of emerging economies are compared to business as usual emissions, the countries’ mitigation potential and respective efforts based on different equity principles. Furthermore, the authors compare the pledges and the identified mitigation potential of emerging economies to a global emissions pathway needed to limit global temperature increase to 2°C. The assessment includes Brazil, China, India, Mexico, South Africa and South Korea.
