Summary
This comprehensive analysis of 20 natural climate solutions across global forests, wetlands, grasslands, and agricultural lands demonstrates that nature-based conservation, restoration, and improved land management can deliver over one-third of the cost-effective climate mitigation required by 2030 to limit warming to below 2 °C. Alongside fossil fuel emissions reductions, NCS offer a robust portfolio of climate actions that simultaneously improve soil health, ecosystem resilience, water and air quality, and biodiversity. The authors acknowledge remaining uncertainties in mitigation estimates but contend the existing evidence base supports immediate global implementation.
UK applicability
The findings are relevant to UK climate and environmental policy, particularly regarding peatland restoration, woodland expansion, regenerative agriculture, and wetland creation—all identified NCS actions applicable to UK geography. However, the paper's global scope and emphasis on tropical forest conservation and large-scale agricultural transition may require contextualisation for temperate UK farming systems and smaller land parcels.
Key measures
Cost-effective climate mitigation potential (gigatonnes CO₂-equivalent); proportion of 2 °C climate stabilisation pathway achievable through NCS between now and 2030; ecosystem co-benefits including soil productivity, water filtration, flood buffering, and biodiversity habitat
Outcomes reported
The study quantified the mitigation potential of 20 natural climate solutions (NCS) actions across forests, wetlands, grasslands, and agricultural lands, demonstrating their contribution to achieving Paris Climate Agreement targets. It assessed both the carbon sequestration and emissions avoidance capacity of these interventions alongside their co-benefits for soil, water, air quality and biodiversity.
