LAND USE MITIGATION: CAN IT REALISTICALLY CONTRIBUTE TO FILL THE GAP TO ACHIEVE THE 1.5 AND 2 ºC GOALS?
Summary
The agriculture and land sectors (AFOLU) contribute approximately 24% of total GHG emissions, but also sequester about one third of annual anthropogenic emissions. While technical potentials for mitigation are high—with some estimates suggesting up to 23.8 GtCO2e yr-1 through conservation and restoration—significant uncertainties remain regarding the persistence of carbon sinks and the practical implementation of large-scale removals. Achieving Paris Agreement goals requires a combination of reducing deforestation, sustainable land intensification, and carbon dioxide removal (CDR) technologies, though these are often hindered by institutional, economic, and socio-cultural barriers rather than just technical limitations.
Key insights
- The agriculture and land sectors (AFOLU) are responsible for roughly 24% of global greenhouse gas emissions, split evenly between land use and agriculture.
- Current Nationally Determined Contributions (NDCs) from 120 countries include land-related reductions; if fully implemented, these would account for 10%-30% of total emission reductions by 2030.
- IPCC scenarios for limiting warming to 2°C and 1.5°C rely on large-scale greenhouse gas removals from the atmosphere, starting as early as the 2020s.
- Technical potential for land use mitigation is high, with some research suggesting a maximum potential of 23.8 GtCO2e yr-1 through restoration and improved management, significantly higher than previous estimates of 11.3 GtCO2eq yr-1.
- The effectiveness of land use mitigation is constrained by institutional, economic, and socio-cultural barriers, as well as uncertainties regarding the future resilience of biosphere carbon sinks.
- Carbon dioxide removal (CDR) strategies include both natural solutions, such as afforestation and soil carbon enhancement via biochar, and technological approaches like bio-energy with carbon capture and storage (BECCS) and direct air capture and storage.
