Belém Declaration on Fertilisers

Joint Brazil–UK ministerial call to action on fertilisers

Today, 19 November 2025, the UK and Brazil have announced a global call to action on fertilisers, furthering our partnership on fertilisers to tackle their environmental impact and embrace their economic opportunities.

The Belém Declaration on Fertilisers, launched at COP30 in Brazil this year, urges for more to be done to enhance nutrient use efficiency and reduce emissions from fertiliser production as a key pathway to delivering climate goals, protecting and restoring nature, and ensuring food security for all in an equitable and just manner.

The need for international collaboration is clear. The 2025 Breakthrough Agenda report chapter on fertilisers published by the International Energy Agency (IEA) in collaboration with the Climate Champions Team suggested 4 key pillars to focus on:

• standards and certification
• demand creation
• finance and investment
• research and innovation

Under the Global Climate Action Agenda at COP30 this year, the UK has also collaborated on a Plan to Accelerate Fertiliser Solutions to assess actions already underway, identify gaps, promote acceleration of those actions and coordinate across organisational barriers to deliver change.

The UK is committed to working with partners to champion the critical role of sustainable agriculture and food systems. Together, we aim to mobilise greater action into nature-positive, climate-resilient agricultural solutions, ensuring that feeding the world does not compromise our climate, ecosystems, or future generations.
