The interactions between mitigation policies could hinder China’s progress toward carbon neutrality by limiting the space for effective policy implementation. Policymakers should emphasize optimizing the combination of these policies to ensure efficient decarbonization.

Achieving sustainable agriculture requires a comprehensive understanding of nitrogen fertilizer production, particularly ammonia. This study shows that low-carbon approaches, such as carbon capture, electrolysis and bioprocessing, can reduce emissions but face cost, resource and reliance challenges. Decentralized production can lower emissions, costs and import dependency, boosting productivity in the global south, but demands policy support.

Land-based carbon dioxide removals are critical for meeting the low-warming targets, yet their availability is limited when avoiding excessive risks to sustainability. Scenario-based analysis suggests that they should only be used to compensate for emissions from hard-to-abate sectors and overshoot.

Calcite has a higher carbon dioxide uptake efficiency and lower cost than dunite, and it is a preferable material for enhanced benthic weathering as a carbon dioxide removal method, according to an analysis that combines laboratory incubation, benthocosm experiment, and numerical box model.

Climate change has negatively impacted grassland productivity in Africa. Climate-smart technologies such as forage grass, legume, and herb mixtures could enhance grassland productivity and resilience, offering a sustainable solution for African pasture-based livestock systems.
