Under the International Programme for Action on Climate (IPAC), The Climate Action Monitor provides an overview of countries’ greenhouse gas emissions, emissions targets, climate-related hazard impacts and climate policy action.
Launched in 2021 at the OECD Ministerial Council Meeting and overseen by the OECD Environment Policy Committee and its Working Party on Environmental Information (WPEI), IPAC tracks progress towards achieving net‑zero greenhouse gas emissions and building a more resilient economy by 2050. To this end, IPAC equips governments with an indicator dashboard and analytical reports to evaluate and assess climate action using official and validated data. While coverage is still evolving, the priority is to develop a coherent set of indicators to support the transition to net zero.
IPAC builds on OECD research and develops new datasets and indicators in collaboration with organisations such as the International Energy Agency, the International Transport Forum, the Nuclear Energy Agency, and the UNFCCC, to capture the environmental, economic, and social dimensions of climate impacts and government responses.
