Global Carbon Project The Global Carbon Project is an international research initiative that quantifies global carbon dioxide and methane sources, sinks, and budgets. It provides annual assessments that inform climate science, connect observational networks, and guide international negotiations, contributing to work by Intergovernmental Panel on Climate Change, United Nations Framework Convention on Climate Change, and national research programs. The Project convenes scientists across observational networks, model intercomparison projects, and assessment bodies to produce datasets used by agencies such as National Aeronautics and Space Administration, National Oceanic and Atmospheric Administration, and the European Commission.
Overview
The Project synthesizes observations from atmospheric monitoring networks like Global Atmosphere Watch, ocean programs such as the Global Ocean Observing System, and terrestrial inventories from institutes including Food and Agriculture Organization and International Institute for Applied Systems Analysis. It integrates outputs from model consortia such as the Coupled Model Intercomparison Project and the Atmospheric Chemistry and Climate Model Intercomparison Project, and engages with satellite missions like OCO-2, Copernicus Programme, and Sentinel satellites. Outputs feed assessments by World Meteorological Organization and scenario analyses by groups behind the Shared Socioeconomic Pathways.
History and Organization
Founded in 2001 under initiatives linked to Earth System Science Partnership and later associated with Future Earth, the Project brought together researchers from Commonwealth Scientific and Industrial Research Organisation, Scripps Institution of Oceanography, CSIC, Centre National de la Recherche Scientifique, and universities including University of East Anglia and MIT. Governance has involved steering committees with representatives from International Council for Science and regional research centers such as Asian Pacific Network. Leadership and working groups coordinate annual budget reports, with secretariat support from partner institutions like Global Change SysTem for Analysis, Research and Training and national programs including Australian Research Council.
Research Activities and Methodologies
The Project combines multiple methodologies: atmospheric inversion techniques used by groups at NOAA, bottom-up inventories following guidelines of Intergovernmental Panel on Climate Change and IPCC National Greenhouse Gas Inventories Programme, ocean carbon measurements aligned with the Global Ocean Ship-based Hydrographic Investigations Program, and terrestrial carbon flux studies using eddy-covariance networks like FLUXNET. It employs data-assimilation frameworks from European Centre for Medium-Range Weather Forecasts and model benchmarking approaches from the Model Intercomparison Project on the climatic response to CO2 perturbation community. Remote sensing inputs derive from missions such as Terra (satellite), Aqua (satellite), and Jason-3, while isotopic fingerprinting methods connect to laboratories at Max Planck Institute for Biogeochemistry and Lawrence Berkeley National Laboratory.
Major Findings and Reports
Annual Global Carbon Budgets produced by the Project document trends in fossil fuel emissions, land-use change, and natural sinks, showing persistent increases in emissions reported by agencies including BP (energy company) and national statistical offices. Reports highlight contributions of cities and regions referenced in analyses by C40 Cities Climate Leadership Group, and link to economic assessments from institutions like the International Energy Agency and World Bank. Findings have clarified roles of tropical forests studied in work by Amazon Cooperation Treaty Organization and peatlands examined by United Nations Environment Programme, and have quantified ocean uptake trends relevant to research at Scripps Institution of Oceanography and Woods Hole Oceanographic Institution.
Impact and Influence on Policy
The Project’s datasets are used in negotiations at Conference of the Parties to the UNFCCC and inform national commitments under the Paris Agreement. Its work underpins policy briefings for bodies such as the European Parliament and ministries including United States Department of Energy and Ministry of Environment and Forests (India). Non-state actors—Climate Action Network, World Resources Institute, and corporations tracked by Carbon Disclosure Project—also use the Project’s outputs for reporting and target-setting, influencing carbon accounting standards and emissions trading discussions involving entities like the European Union Emissions Trading System.
Collaborations and Funding
The Project collaborates with networks and institutions including International Geosphere-Biosphere Programme, Global Carbon Atlas, and regional centers such as Asia-Pacific Network for Global Change Research. Funders and supporting agencies have included national research councils like the National Science Foundation, philanthropic organizations such as the Gordon and Betty Moore Foundation, and multilateral entities like the European Commission. Partnered projects span observational consortia, model intercomparison initiatives, and synthesis centers including Potsdam Institute for Climate Impact Research.
Criticisms and Challenges
Critiques directed at the Project include uncertainties in bottom-up inventories emphasized by analysts at Organisation for Economic Co-operation and Development and challenges reconciling atmospheric inversions from different groups such as LSCE and Met Office. Debates persist about attribution of land-use emissions referenced by Forest Stewardship Council advocates and the representation of emissions from complex economies studied by International Monetary Fund. Technical challenges include sparse observations in regions represented by institutions like African Academy of Sciences and reconciling satellite retrieval biases raised by teams at Jet Propulsion Laboratory.
