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 2021. 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 how they could accelerate the delivery of long-term mitigation goals. Specifically, this includes the use of carbon taxes, emissions trading systems and crediting mechanisms. International cooperation on carbon pricing and the status of work surrounding Article 6 of the Paris Agreement is also canvassed. The World Bank has also created a Carbon Pricing Dashboard which shows a map and key statistics on carbon pricing initiatives around the world.
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 December 2020 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. According to the report, in order to limit the temperature rise to 1.5°C, global emissions must drop rapidly to 25 Gt CO2e by 2030; however, based on current commitments under the Paris Agreement, emissions are on track to be 56 Gt CO2e in 2030, over twice what they should be. A summary of the report can be found here.
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 2021” provides a comprehensive snapshot of the latest developments in emissions trading around the world. Articles from policymakers and government advisors present insights on the newly launched Chinese national ETS and UK ETS as well as system reviews and reforms in the EU ETS, the Regional Greenhouse Gas Initiative (RGGI), New Zealand, and the Republic of Korea. Their website can be found here.
Echosystem Marketplace, an initiative of the non-profit organization Forest Trends, was initially created to improve transparency and price discovery in the voluntary carbon markets, as there is no centralized system for transacting voluntary carbon credits. 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. In 2020, they published two installments of their “State of the Voluntary Markets” report. The first installment discussed key insights and findings garnered from their annual survery. The second installment presented additional market data such as how voluntary carbon offset market participants price both core carbon and additional attributes (e.g., project types, co-benefits, location, vintage).
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.
