Knowledge & Insights.

Long-form explainers and insights on carbon credit projects, CORSIA, Gold Standard, ICVCM, and the breadth of SaniTap's work in Madagascar. Written for procurement teams, ESG buyers, project finance professionals, and anyone wanting the detail behind the headlines.

CORSIA explained for procurement and ESG teams

A structured working briefing on the Carbon Offsetting and Reduction Scheme for International Aviation — its regulatory anatomy, phasing, offset arithmetic, eligibility mechanics, and the five questions procurement teams should ask any project developer claiming a CORSIA pathway.

The path to CORSIA eligibility — what Gold Standard projects must add

Programme-level approval is a necessary but not sufficient condition. This piece dissects the delta between Gold Standard certification and CORSIA eligibility — Article 6 authorisation, vintage regimes, phase-specific criteria, and the practical workstreams a serious project developer must maintain to satisfy the CORSIA envelope.

ICVCM Core Carbon Principles in plain language

The Integrity Council for the Voluntary Carbon Market's Core Carbon Principles are the emerging integrity benchmark for voluntary credits. This is a substantive walkthrough of all ten principles — what each requires at programme and project level, how the assessment operates, and how the CCP mark interacts with other integrity frameworks buyers are converging on.

What gender-responsive carbon credits actually mean

"Gender-responsive" is a Gold Standard certification tier that goes materially beyond gender-sensitive consultation. This piece explains the three-tier framework, sets out what the higher tier substantively requires, why gender-disaggregated monitoring materially strengthens the carbon claim itself, and how the framework maps onto ICVCM Principle 9 and broader sustainable-development integrity expectations.

How safe water displaces carbon emissions — the boil-water story

Safe-water carbon credits are less intuitive than clean-cookstove credits, yet the accounting logic is rigorous. This piece walks through the counterfactual mechanics that underpin Gold Standard's ERSDWS v1.0 methodology, the epidemiology of boil-water behaviour, why fNRB matters as much here as for cookstoves, and where the audit-defensibility of the credits rests.

Methodology

TPDDTEC v4.0 — how clean cookstove credits are calculated

Gold Standard's Technologies and Practices to Displace Decentralised Thermal Energy Consumption methodology is the foundational instrument for high-integrity clean-cookstove carbon credits. This is a technical walk-through of the version 4.0 framework — baseline construction, fNRB, WBT and KPT protocols, conservative discount factors, and the verification cycle — for readers who need to interrogate what a credit actually represents.

Story

Why Madagascar — the case for action

Madagascar sits at the intersection of extreme climate vulnerability, extreme water insecurity, and an unusual carbon-integrity opportunity. This piece sets out the country-specific context — the epidemiology, the hydrology, the deforestation flux, the aid-funding gap — that makes Madagascar's climate and WASH crisis distinctive, and explains why carbon-financed intervention there is more than usually consequential.

Story

The SaniTap–MadAvance model — company speed, NGO trust

The SaniTap–MadAvance structure is deliberately different from the standard patterns in impact-and-development work. This piece explains what the model is, what it has delivered, why the pairing works structurally rather than incidentally, and what the design implies for the carbon-integrity of the projects it operates.
