There were 75 carbon pricing mechanisms in operation worldwide as of April 1, 2024, covering roughly 13 billion metric tons of carbon dioxide equivalent. These comprised 39 carbon tax initiatives and 36 Emissions Trading Systems (ETS). 13 ETS were national initiatives, while 23 were sub-national initiatives, such as the RGGI in the U.S. The only regional ETS in place was the EU ETS. The number of operating carbon pricing mechanisms has increased considerably in recent years.

The share of global greenhouse gas emissions covered by a direct carbon price are calculated based on direct carbon pricing instruments in operation. The calculation of emissions coverage by carbon pricing instruments is based on official government sources, though these do not necessarily factor in exemptions and/or emissions thresholds.
