CARBON & IMPACT
The data earned us the compliance market.
Most cookstove projects sell voluntary credits based on survey estimates. ACE sells Article 6 compliance credits backed by measured stove usage.
Fifteen years of operations. 100,000+ units deployed. Every cooking session logged.

ARTICLE 6 OF THE PARIS AGREEMENT
Sovereign-grade carbon, because the data holds up.
Article 6 is the Paris Agreement mechanism that enables sovereign-level transfer of verified emission reductions between countries. It is how compliance buyers meet legally binding climate obligations.
ACE's carbon programmes sit in this market - not because we talked our way in, but because our device-level monitoring produces the kind of data compliance buyers can underwrite.
CARBON INTEGRITY
Five rules we don't break.
Clean cooking carbon has a credibility problem. We built our programme around not repeating the sector's mistakes.
01
Device-level monitoring
Usage recorded for each individual stove, not estimated from samples or surveys.
02
Conservative accounting
Leakage deductions, precision discounts, and statistical validation applied to all calculations.
03
No data, no credit
If usage data is missing for a stove during a monitoring period, no emission reductions are claimed.
04
Independent verification
All emission reductions validated and verified by accredited third-party bodies.
05
Rigorous field testing
Quarterly Kitchen Performance Tests at 95% confidence / 5% precision - more rigorous than typical cookstove projects.
