Climate change

The energy sector is central to efforts to combat climate change

Promoting sustainable development and combating climate change have become integral aspects of energy planning, analysis and policy making. Energy accounts for two-thirds of total greenhouse gas, so efforts to reduce emissions and mitigate climate change must include the energy sector.

Driven by higher energy demand in 2018, global energy-related CO2 emissions rose to a historic high

Driven by higher energy demand in 2018, global energy-related CO2 emissions rose 1.7% to a historic high of 33.1 Gt CO2. While emissions from all fossil fuels increased, the power sector accounted for nearly two-thirds of emissions growth. Coal use in power alone surpassed 10 Gt CO2, mostly in Asia. China, India, and the United States accounted for 85% of the net increase in emissions, while emissions declined for Germany, Japan, Mexico, France and the United Kingdom.
