Brazil and the United Kingdom (UK) jointly announced a non-binding declaration at COP30 to improve fertilizer use efficiency in support of food security, environmental protection, and climate goals. The initiative aims to reduce emissions and nutrient pollution while maintaining agricultural productivity, particularly in emerging economies. WRI highlighted that fertilizer production and mismanagement are a critical mitigation lever, as they contribute significantly to GHG emissions and water pollution. The declaration encourages collaboration on policy reform, innovation, and investment to support improved nutrient management practices. While it signals growing recognition of fertilizers as a strategic nexus linking climate mitigation, food systems, and nature protection, its impact will depend on follow-through through national policies, financing mechanisms, and implementation at the farmer level.
