A quarter of the global GHG emissions comes from coal combustion. This is evident from an updated version of a flow chart showing the global greenhouse gas emissions. The flow chart shows, from beginning to end, where greenhouse gases come from and how much of each gas ends up in our atmosphere. It was created in a collaboration with ASN Bank and Ecofys.
The previous update of the GHG flow chart used data for 2010 while the current version uses data from 2012. In that period, the global greenhouse gas emissions grew from 48,629 megatonnes in 2010 to 51,840 megatonnes in 2012.
The flow chart shows which sectors contribute to global greenhouse gas emissions the most and what the sources of their emissions are. The World GHG Emissions Flow Chart was originally launched in 2000 by the World Resources Institute. Since then, the flow chart has become one of the most commonly used charts to provide insights into greenhouse gases and climate change.
