REgional Carbon Cycle Assessment and Processes’, Phase 2 (RECCAP-2) is coordinated by the Global Carbon Project, and collects and synthesises regional data for 14 large regions of the globe with a requirement of harmonisation sufficient to be able to scale these budgets to the globe and to compare different regions.
Key policy-relevant challenges for the scientific community and objectives of the RECCAP-2 project are to:
- Improve quantification of anthropogenic greenhouse gas emissions and their sources;
- Develop robust observation-based estimates of changes in carbon storage and greenhouse gas emissions and sinks by the oceans and terrestrial ecosystems, distinguishing whenever possible anthropogenic vs. natural fluxes and their driving processes;
- Gain science-based evidence of the response of marine and terrestrial regional GHG budgets to climate change and direct anthropogenic drivers.
