Global carbon market size 2018-2021
The value of the global carbon market soared 164 percent in 2021 to a record high of 760 billion euros. This growth was mainly due to an increased demand for carbon permits, which culminated in surging prices. Carbon trading is the purchase and sale of credits that allow a company or entity, such as a power plant, to emit a certain amount of carbon dioxide. The European Union Emission Trading System is the largest carbon market based on value, and accounted for roughly 90 percent of the global market size in 2021.
