An alliance of first-mover governments, international organisations, and businesses from the food, agriculture, fertilizer, sustainable fuels, and manufacturing sectors has united at COP30 in Brazil to accelerate scale adoption of low-emission ammonia-based fertilizers through the Low-Emission Ammonia Fertilizer (LEAF) Initiative.
Nitrogen fertilizers are essential to global food security, supporting the harvests that feed communities worldwide. Yet conventional ammonia-based fertilizer production accounts for 510 million t of greenhouse gas emissions globally – a footprint comparable to Brazil’s or Germany’s total annual emissions. Reducing these emissions while maintaining essential nutrient supply and safeguarding food security and affordability requires a comprehensive, industry-wide effort underpinned by strong public-private collaboration.
The LEAF Initiative is designed to operationalise global efforts advancing collaborative action, particularly the Breakthrough Agenda, as well as the COP30 Plans to Accelerate Solutions and bilateral partnerships such as the one between the governments of the United Kingdom (UK) and Brazil. These global initiatives identify core areas for collaboration, all of which are addressed by the COP30 LEAF Initiative and its dedicated Public-Private Action Statement, launched on 8 November 2025, at COP30.
The LEAF Initiative has been championed by the Hydrogen Council and partners, including Breakthrough Agenda, United Nations Industrial Development Organisation (UNIDO), PepsiCo, 3Degrees Low-Emission Fertilizer Alliance, Rocky Mountain Institute, Centre for Green Markets Activation, World Business Council for Sustainable Development, International Fertilizer Association, Mission Possible Partnership, Hydrogen Europe, Ammonia Energy Association.
The Public-Private Action Statement identifies three key priorities for collective action:
- Accelerate large scale investments by closing the cost gap and activate demand.
- Boost investor confidence and reduce transaction costs through standards and market-based mechanisms.
- Advance public-private collaboration on policy frameworks and financial instruments.
The Action Statement remains open for endorsements by 20 November, COP30 Thematic Day for Agriculture, Food Systems and Food Security, Fisheries, and Family Farming.
To support this initiative, the Hydrogen Council published the Roadmap to Scale Low-Emission Ammonia Fertilizers, in collaboration with key agri-food stakeholders and McKinsey & Company. The roadmap provides insights into market fundamentals and analytics supporting the key priority actions.
Jim Andew, PepsiCo Chief Sustainability Officer, said: “The global food system is at an inflection point where scaled investment, enabling policies and collective action are needed to transform agricultural systems, build resilience and safeguard long-term food security. At COP30, PepsiCo is proud to support the LEAF Initiative in advancing the adoption of low-emission fertilizer solutions as a means of decarbonising agriculture while continuing to prioritise support for farmers to do what’s best for their farms, their livelihoods, and the planet.”
Petra Schwager, Chief of the Climate and Technology Partnership (CTP) Division, UNIDO, commented: “UNIDO recognises the vital role of low-emission ammonia fertilizers in building resilient and sustainable agrifood systems. UNIDO is proud to support the Public-Private Action Statement, helping countries decarbonise fertilizer production while improving food security and promoting sustainable industrial development. In particular, through technical assistance, policy advisory and capacity-building tailored to national contexts – especially in developing countries where access to affordable fertilizers remains a critical challenge. UNIDO is committed to scaling up these efforts and invites partners to collaborate in making low-emission fertilizers a cornerstone of resilient, decarbonised food systems.”
Ivana Jemelkova, CEO of Hydrogen Council, added: “COP30 is all about walking the talk, which is why we are proud to convene the LEAF Initiative with first movers across energy and food systems. It is strong alliances like these that turn ambition into impact through concrete joint action plans – creating lead markets for clean hydrogen and low-emission solutions that drive sustainability, security, and resilience.”
