Greenhouse Gases

Greenhouse gases, and CO2 in particular, have risen to the top of the list of the energy sector's environmental impacts, as the source of human-made climate change. For more than a decade, the IEA has worked on efficient and effective climate mitigation policies for the energy sector, with work ranging from emissions trading, to energy efficiency policy and technology RD&D.

The IEA also publishes global annual statistics on CO2 emissions from fossil fuel combustion and monitors sector-level evolution in energy use and associated CO2 emissions, all critical information to identify policy priorities.
