Greenhouse Gas Removal (GHG-R)
The focus of the Flagship Destination is to remove gigatons of carbon dioxide and carbon dioxide equivalents from the atmosphere per year by mid-century through an integrated approach that will support the development of needed technological, governance, financial, and other societal innovations, including addressing equity and justice issues.
To prevent global warming above 1.5 degrees as outlined in the Paris Agreement, we not only need to reduce greenhouse gas emissions, we need to proactively remove carbon from the atmosphere. Reaching this goal will require experts in policy, technology, nature-based solutions, and other areas working together globally.

2024 Projects
In March 2024, the GHG-R Flagship selected its initial 16 projects spanning terrestrial, oceanic, direct GHG removal, and monitoring, reporting, and verification (MRV) sub-categories. The projects are high-risk/high-reward approaches with a range of readiness from scoping to scale-up advancement. The projects embrace innovation and novel technologies for GHG-R at the gigaton scale.
