CORSIA.
SaniTap is progressing its Gold Standard projects toward CORSIA eligibility — for airlines, obligated buyers, and organisations aligning voluntary purchases with the compliance frameworks that set the future floor for credit quality.
The aviation industry's offsetting scheme.
The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), established by the International Civil Aviation Organization (ICAO), is a global market-based mechanism designed to stabilise net CO₂ emissions from international aviation.
Under CORSIA, airlines must offset eligible emissions growth above defined baselines using approved, high-quality carbon credits. The scheme complements the Paris Agreement by supporting international cooperation to reduce global greenhouse gas emissions while maintaining strict environmental-integrity criteria for eligible credits.
What makes a credit CORSIA-eligible.
CORSIA eligibility requires projects to meet additional screening requirements beyond standard certification.
Additionality
Strict criteria on impact additionality — would the emissions reductions have occurred without carbon finance?
No double counting
Robust safeguards against double-counting across markets, registries, and national inventories.
Registry transparency
Issuance through transparent, audited registries with full traceability from project to retirement.
Host-country authorisation
Article 6 authorisation by the host country, where applicable — confirming a credit may transfer internationally.
Where we sit on the pathway.
SaniTap's Gold Standard-certified clean cooking and safe water projects are on the path to CORSIA eligibility. Three workstreams are active.
Government engagement
Letter of Approbation in hand from the Government of Madagascar — formal host-country support for the project pipeline. Work continues toward full Article 6 authorisation for international transfer.
Programme alignment
Aligning project documentation and monitoring systems with CORSIA-approved programme requirements, ahead of evolving ICAO guidance.
Integrity stacking
Credits already developed to the gender-responsive certification level and aligned with the ICVCM Core Carbon Principles — exceeding the minimum integrity bar.
If you're a CORSIA-obligated buyer.
