Contributions of country-level net land carbon sinks to inclusive wealth 1: Kiel Institute for the World Economy, Germany; 2: Earth Systems and Global Change Group, Wageningen University & Research, Netherlands; 3: School of Public Policy, Georgia Institute of Technology, Atlanta, US; 4: Department of Geography, Ludwig Maximilian University Munich, Germany; 5: Max Planck Institute for Meteorology, Hamburg, Germany; 6: Department of Economics, Kiel University, Germany Land ecosystems, especially forests and soils, sequester substantial amounts of CO2, though this is partially offset by land-use change emissions, such as deforestation. While separating natural from anthropogenic fluxes remains challenging, the net land sink clearly contributes to climate change mitigation and thereby to inclusive wealth. Here, we estimate the country-level social cost of carbon (CSCC), reflecting climate change’s economic impact on individual countries, and combine this with recent data on land-based carbon fluxes to evaluate their contribution to comprehensive investment globally, nationally and across borders. Globally, the current net land sink provides a median value of US$454.86 billion per year (2020 prices, 66% CI -46.74 to 1,436.48). Russia contributes the most to other countries via its net land carbon sink, US$105.94 billion per year (median; 66% CI -1.44 to 311.51). The cross-border contributions must be balanced with benefits received. For example, India, despite being the sixth-largest net land carbon sink, shows a negative transboundary balance of -US$141.71 billion per year (median; 66% CI -352.35 to 5.15). However, India has the highest CSCC implying that India’s benefits from the net land sink abroad are valued higher than other countries’ benefits from India’s domestic land sink. | |
