The World Bank has released its annual report “State and Trends of Carbon Pricing 2023”, which provides an updated overview of existing and emerging carbon pricing instruments around the world, including international, national and sub-national initiatives.

The World Bank has been tracking carbon markets for around two decades and the annual State and Trends of Carbon Pricing report is now in its tenth year. When the first report was published a decade ago, only 7% of global emissions were covered by either a carbon tax or an ETS. Today, as highlighted in the 2023 report, almost a quarter of global greenhouse gas emissions (23%) are now covered by 73 instruments. An ETS places a limit on the amount of greenhouse gas emissions – it allows emitters with lower emissions to sell their extra emission units (or “allowances”) to higher emitters, thereby establishing a market price for emissions. A carbon tax, meanwhile, directly sets a price on carbon by defining a tax rate on emissions.

While the uptake of ETS and carbon taxes is on the rise in emerging economies, high-income countries still dominate. New instruments were implemented in Austria and Indonesia, as well as in subnational jurisdictions in the United States and Mexico. Australia is scheduled to recommence carbon pricing with a rate-based ETS due to start in July 2023 and countries including Chile, Malaysia, Vietnam, Thailand and Türkiye continue to work towards implementing direct carbon pricing.

Issuances and retirements of carbon credits fell slightly compared to 2021. Macroeconomic conditions, criticism of carbon credits and offsetting, and bottlenecks in issuance are among the causes of this slight slowdown over the past year. However, the report finds promising signs of cooperation between countries on carbon markets under the Paris Agreement framework.

The report reiterates that carbon pricing is an important tool to raise revenue, direct international financial flows, and drive innovation. As part of a broader policy package, these policies can help deliver on broader sustainability and development goals. For instance, many of the World Bank’s core climate diagnostics, the Country Climate and Development Reports, highlight the potential for direct carbon pricing policies to support countries on their development journeys.

The “State and Trends of Carbon Pricing” report was launched at Innovate4Climate, the World Bank Group’s flagship climate action event held this year in Bilbao, from May 23 to 25. Now in its seventh year, the I4C conference promotes a global dialogue between the public and private sectors, showcasing the opportunities and innovations for low-carbon, resilient development, and fostering exchange of knowledge to promote investments in transformative climate-smart solutions.
