The Intergovernmental Panel on Climate Change (IPCC) is gathering over 150 experts in Rome, Italy, this week to begin work on the 2027 Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture, Utilisation, and Storage (CDRT-CCUS).
The first meeting of authors of the Methodology Report is taking place from April 14 to 16, 2026, at the headquarters of the Food and Agriculture Organisation (FAO) in Rome.
The 2027 Methodology Report on Carbon Dioxide Removal Technologies and Carbon Capture, Utilisation, and Storage will equip governments with a robust, up‑to‑date scientific foundation for estimating CO₂ emissions and removals from these technologies.
“This Methodology Report will serve as a fundamental reference for transparent and consistent reporting on climate action, strengthening the scientific basis for mitigation policies,” said Takeshi Enoki, the Co-Chair of the IPCC Task Force on National Greenhouse Gas Inventories (TFI).
The CDRT-CCUS Methodology Report will provide comprehensive guidance on a wide range of carbon dioxide removal and storage approaches, from CO₂ capture, utilisation, and long‑term storage to emerging land‑based and coastal solutions. It will offer updated scientific methods for assessing technologies such as direct air capture, soil and biomass-based removals, coastal ecosystem approaches, and the production of durable CO₂‑derived materials.
“Together, these updates will strengthen countries’ ability to consistently estimate and report emissions and removals across the full spectrum of methods covered by the IPCC guidelines,” said Mazhar Hayat, the other TFI Co-Chair.
The IPCC Task Force on National Greenhouse Gas Inventories is responsible for developing and improving internationally agreed methodologies and tools for estimating and reporting greenhouse gas emissions and removals by signatories of the United Nations Framework Convention on Climate Change (UNFCCC) and its Paris Agreement.
As other IPCC reports, this Methodology Report will be prepared through a structured and transparent IPCC process, with four Lead Author meetings where the report’s content will be developed and refined in line with approved guidance.
It will undergo two formal review stages, first by experts and then by governments and experts jointly, before the final approval by IPCC member governments at the end of 2027.
