About SaniTap
What does SaniTap do?
SaniTap is an impact business specialising in the development of scalable climate mitigation and adaptation projects, including high-quality carbon credit projects. We design, implement, and manage climate projects that reduce carbon emissions while delivering safe drinking water, clean cooking solutions, and long-term health and environmental benefits for low-income communities in Madagascar.
Is SaniTap a business, an NGO, or a charity?
SaniTap operates as a mission-driven impact business. We generate revenue through the sale of verified carbon credits, which enables us to scale impact sustainably while reinvesting in high-integrity climate and community projects. Our implementing partner MadAvance — co-founded by SaniTap in 2023 — is a Malagasy NGO.
Where does SaniTap operate geographically?
Our core operations are in Madagascar, where we work with local partners and communities to implement carbon projects. SaniTap Ltd is headquartered in the UK. We collaborate internationally with corporate buyers, investors, and partners seeking high-integrity carbon credits.
What types of organisations does SaniTap work with?
We work closely with corporates, financial institutions, brokers, NGOs, philanthropic foundations, and public-sector partners. Our clients include organisations looking to purchase carbon credits, develop new carbon projects, or design innovative climate finance solutions. CORSIA-obligated airlines and corporate ESG procurement teams are a core audience.
How does SaniTap differ from other carbon project developers?
SaniTap combines deep local implementation experience in Madagascar with international carbon market expertise. Our projects integrate climate mitigation or adaptation with tangible sustainable development outcomes — safe water access, reduced waterborne disease, reduced indoor air pollution — and stack integrity above the minimum: Gold Standard, gender-responsive certification, ICVCM CCP alignment, and third-party sensor monitoring on a randomised sample.
What expertise does the SaniTap team bring to carbon project development?
Our team combines decades of on-the-ground implementation experience with carbon methodology expertise, project structuring, climate finance, MRV system design, and stakeholder engagement. Co-founders Andrew Tanswell and Adriaan Mol have over 60 years of combined experience building impact ventures across Africa.
How does SaniTap work with local communities and partners?
We co-design projects with local partners and communities through our partner organisation MadAvance — a Malagasy NGO with more than 80 local staff. Stakeholder engagement runs at community, regional, and national levels, with ongoing feedback and grievance mechanisms maintained throughout the project lifetime.
Can SaniTap support organisations looking to develop their own carbon projects?
Yes. SaniTap provides end-to-end carbon project development support through our Carbon-as-a-Service consulting practice — feasibility studies, methodology selection, project design, MRV system implementation, certification support, and climate financing structuring.
Carbon Credits
What types of carbon credits does SaniTap develop and sell?
SaniTap currently develops carbon credits from clean cooking and safe drinking water projects under the Gold Standard for Global Goals. We are also developing pilot projects in nature-based carbon removal — biochar, riparian bamboo, and afforestation, reforestation and revegetation (ARR) — and in cyclone-resistant infrastructure under the Adaptation Benefits Mechanism.
Are SaniTap's carbon credits verified by recognised standards?
Yes. Our projects are developed under the Gold Standard for Global Goals — one of the world's leading carbon standards — with the optional higher-level gender-responsive certification. Credits are also aligned with the ICVCM Core Carbon Principles, and the projects are progressing toward CORSIA eligibility.
How are carbon emission reductions measured and verified?
Emissions reductions are calculated using approved methodologies — TPDDTEC v4.0 for clean cookstoves and ERSDWS v1.0 for safe water — and independently verified by accredited third-party auditors. Monitoring data is collected continuously through field operations and, on a randomly selected sample, through independent third-party sensor monitoring.
What is the Gold Standard and why does it matter?
Gold Standard is one of the world's leading carbon standards, known for rigorous requirements on environmental integrity, additionality, conservative quantification, and sustainable development. Credits issued under the Gold Standard for Global Goals are widely accepted by corporate buyers and are approved by ICAO for CORSIA programme-level eligibility.
How can organisations purchase carbon credits from SaniTap?
Organisations can purchase credits directly by contacting SaniTap's commercial team. We support spot purchases, multi-year offtake agreements, and tailored arrangements based on your climate strategy and CORSIA-pathway timing.
Can SaniTap provide long-term or forward contracts for carbon credits?
Yes. We work with buyers to structure forward agreements and long-term offtake contracts, supporting project scalability while helping organisations plan their future carbon needs around Phase 1 and Phase 2 of CORSIA.
How does SaniTap ensure the additionality and permanence of its projects?
Our projects meet strict additionality criteria — the emissions reductions would not occur without carbon finance, particularly the long-term maintenance funding that traditional aid programmes do not provide. Permanence is structural rather than buffered: a litre of water not boiled is not boiled, and a unit of biomass not burned is not burned.
Are SaniTap's carbon credits suitable for corporate net-zero or ESG strategies?
Yes. Our credits are designed for use within corporate climate, net-zero, and ESG strategies — particularly as part of high-quality, beyond-value-chain mitigation. They are well suited to organisations that need credits to survive ESG audit and external assurance.
What information and documentation is provided with each carbon credit purchase?
Buyers receive full documentation: verification reports, project description documents, monitoring reports, serial numbers from the Gold Standard registry, and supporting evidence on co-benefits and SDG impact. Sample documentation is available on request.
How does SaniTap price its carbon credits?
Pricing depends on project type, volume, contract structure, and delivery timeline. Our pricing reflects both market conditions and the true cost of high-integrity impact — including the gender-responsive certification, third-party sensor monitoring, and CORSIA pathway investment that distinguishes our credits.
SaniTap's Impact
What environmental and social impacts do SaniTap's projects deliver beyond carbon reduction?
Beyond greenhouse gas reductions, our projects improve access to clean drinking water, reduce indoor air pollution, lower the incidence of waterborne disease, protect ecosystems from deforestation, and support local livelihoods. Each project tracks measurable co-benefits across health, time-use, gender equality, and economic outcomes.
How does SaniTap measure and report its social and environmental impact?
We track impact using standardised indicators aligned with the Gold Standard for Global Goals SDG Impact framework. Indicators are gender-disaggregated where relevant, monitored continuously through field operations, and externally verified during the credit verification cycle.
How many people have benefited from SaniTap's clean water and clean cooking projects?
More than 500,000 people across low-income, climate-vulnerable communities in Madagascar have benefited from SaniTap's projects to date. The figure grows as projects scale.
How do SaniTap's projects contribute to the UN Sustainable Development Goals (SDGs)?
Our projects principally contribute to six SDGs by integrating climate mitigation and adaptation with health and development outcomes: SDG 1 (No Poverty), SDG 2 (Zero Hunger), SDG 3 (Good Health and Wellbeing), SDG 6 (Clean Water and Sanitation), SDG 13 (Climate Action), and SDG 15 (Life on Land).
How does SaniTap ensure long-term benefits for local communities?
Long-term sustainability is built into project design: local capacity building through MadAvance, water-guardian training and incentives, ongoing maintenance funded by sustained carbon revenue, and embedded governance mechanisms. The 10+ year credit issuance horizon supports the patient capital required for durable outcomes.
What safeguards are in place to avoid negative environmental or social impacts?
All projects follow the safeguards required by the Gold Standard for Global Goals and other recognised international standards: risk assessments, stakeholder consultation at multiple levels, gender safeguarding principles, ongoing grievance mechanisms, and do-no-harm provisions.
How can partners and buyers engage more deeply with SaniTap's impact initiatives?
Partners can engage through long-term carbon offtake agreements, co-developing carbon projects, or supporting our climate mitigation and adaptation innovation pilots. We welcome strategic collaborations aligned with our mission and the CORSIA-eligibility pathway.
