Share of global GHG emissions covered by carbon pricing instruments 2005-2024
Carbon pricing instruments covered almost 13 billion metric tons of carbon dioxide equivalent as of April 2024, representing around 24 percent of global GHG emissions. The share of global GHG emissions covered by carbon pricing mechanisms, like carbon taxes and emissions trading systems, has increased considerably since 2005, the year the EU ETS became the world's first major carbon market.
