It is generally accepted that greenhouse gas (GHG) emissions in the atmosphere venting from anthropogenic sources are in part responsible for global warming, one driver of global climate change. While the reality of global warming itself is still under political and scientific debate, measurements indicate that the average temperature on Earth has increased by 0.7 degrees Celsius since the start of the Industrial Revolution. To estimate the influence of and prevent dangerous interference from anthropogenic sources in the global climate system, reliable estimates of emissions and removal of GHGs from the atmosphere are required, a critical objective of the United Nations Framework Convention on Climate Change (UNFCCC). The charts and graphs below demonstrate existing data to this aim, reflecting information about the contribution of countries worldwide to GHG emissions and emissions by source.
