World Bank Group

For the last few years, the World Bank has published the “State and Trends of Carbon Pricing.” Their most recent report was published in May 2023. Every year this report is an up-to-date overview of existing and emerging carbon pricing instruments around the world, including international, national and subnational initiatives. It also investigates trends surrounding the development and implementation of carbon pricing instruments and some of the drivers seen over the past year. Specifically, this includes the use of carbon taxes, emissions trading systems, and crediting mechanisms. Key topics covered in the 2023 report include how governments have responded to the global energy crisis, uptake of ETSs and carbon taxes in emerging economies, and progress in carbon markets and supporting frameworks, including implementation of Article 6 of the Paris Agreement. The World Bank has also created a Carbon Pricing Dashboard which shows a map and key statistics on carbon pricing initiatives around the world.

UN Environment Programme

For over a decade, the UN Environment Programme (UNEP) Emissions Gap Report has provided a yearly review of the difference between where greenhouse emissions are predicted to be in 2030 and where they should be to avoid the worst impacts of climate change. The most recent report was published in November 2023 and presents the latest data on the expected gap in 2030 for the 1.5°C and 2°C temperature targets of the Paris Agreement. Predicted 2030 greenhouse gas emissions must fall by 28% for the Paris Agreement 2°C pathway and 42% for the 1.5°C pathway. As things stand, fully implementing unconditional Nationally Determined Contributions (NDCs) made under the Paris Agreement would put the world on track for limiting temperature rise to 2.9°C above pre-industrial levels this century. Fully implementing conditional NDCs would lower this to 2.5°C.

International Carbon Action Partnership

The International Carbon Action Partnership (ICAP) is an international forum for governments and public authorities that have implemented or are planning to implement emissions trading systems (ETS). ICAP facilitates cooperation between countries, sub-national jurisdictions and supranational institutions that have established or are actively pursuing carbon markets through mandatory cap-and-trade systems. ICAP’s “Emissions Trading Worldwide: Status Report 2023” provides a detailed picture of the latest developments in emissions trading, with infographics, updated detailed factsheets on the world’s carbon markets and comprehensive articles by ETS policymakers and practitioners from around the world. ICAP’s website can be found here.

Ecosystem Marketplace

Ecosystem Marketplace, an initiative of the non-profit organization Forest Trends, was initially created to improve transparency and price discovery in the voluntary carbon markets. Since 2006, their team has distributed annual surveys to its network of project developers, investors, retailers and brokers to collect confidential information about their voluntary carbon offsets transactions. Their latest report includes data from over 160 respondents, representing credits from 1,530 projects and over 130 project types traded worldwide. The overall value of the voluntary carbon market remained relatively steady in 2022, at just under $2 billion.

Our World in Data

Our World in Data (OWID) is a scientific online publication that focuses on large global problems such as poverty, disease, hunger, climate change, war, existential risks and inequality. Its mission is to present “research and data to make progress against the world’s largest problems.” The web publication contains interactive data visualizations (charts and maps) on global warming and greenhouse gas emissions.
