Carbon Horizon Signs Agreement with DelAgua to Deploy 210,000 Clean Cookstoves in Uganda
Carbon Horizon is pleased to announce that it has signed an investment agreement with DelAgua for the purchase and distribution of 210,000 clean cookstoves in Uganda. Carbon Horizon is the exclusive investor in the project, which is to be registered under Verra’s Verified Carbon Standard (VCS) as the DelAgua Clean Cooking Grouped Project in Uganda (VCS4278).
The project is expected to generate millions of Verified Carbon Units (VCUs), quantified under Verra’s VM0050 methodology - the latest and most rigorous cookstove methodology available. These credits are expected to be eligible for use under Phase II of CORSIA, the International Civil Aviation Organization’s global scheme requiring airlines to offset emissions growth from international flights, which becomes mandatory for participating states from 2027.
About the Project
The cookstoves will be manufactured by BURN Manufacturing, one of Africa’s largest producers of clean cooking technology, and distributed by DelAgua across rural Uganda. DelAgua will manage the full project lifecycle: stove procurement, last-mile distribution, household education, usage monitoring, and credit issuance through Verra.
The project’s registration under VM0050 ensures that credit quantification reflects the best available science on cookstove emissions reductions, including updated fuel consumption baselines, field-level tests, and conservative crediting assumptions designed to avoid over-issuance.
Why This Matters for CORSIA
CORSIA is entering a critical period. Phase I is underway, and with Phase II set to bring mandatory participation for the majority of international aviation activity, demand for eligible emissions units is expected to grow substantially. However, the supply of credits that meet CORSIA’s stringent eligibility requirements, including host country authorisation under Article 6 of the Paris Agreement, registration under an approved methodology and independent verification, remains limited.
DelAgua is one of very few project developers to have already secured CORSIA eligibility tags for its credits across multiple African markets, with over 4.7 million credits recently approved for use under Phase I. Their operational track record, having delivered over two million stoves to more than nine million people across Rwanda, The Gambia and Sierra Leone, gives Carbon Horizon confidence in their ability to execute at scale in a new market.
This investment positions Carbon Horizon to supply millions of high-integrity, CORSIA-eligible credits into a market where credible supply will be one of the defining constraints of the coming decade.
Impact Beyond Carbon
The 210,000 cookstoves deployed through this project will reach over one million people in rural Uganda. Each stove replaces traditional cooking methods that rely on burning wood or charcoal on open fires - a practice linked to severe indoor air pollution, deforestation, and significant time burdens, particularly on women and children. By using substantially less wood and producing far less smoke, the improved stoves directly reduce household air pollution while easing pressure on Uganda’s forests.
Looking Forward
This agreement represents Carbon Horizon’s largest single project investment to date and a significant step in building a portfolio of CORSIA-aligned credit supply. As the aviation industry prepares for the compliance obligations ahead, partnerships like this one, grounded in proven methodology, operational credibility, and measurable impact, are exactly what the market needs.
We look forward to sharing further updates as the project progresses from manufacturing through to distribution and first credit issuance.
