Gold Standard has published PARC, its first biochar carbon removal methodology. Credits are based on carbon expected to stay stored for at least 200 years, with a stricter 1,000-year claim requiring additional analysis. The methodology sets a five-to-one storage threshold, meaning projects must store five units of CO2 for every unit of activity emissions before any credits are issued. PARC introduces three compliance tracks based on production scale: distributed kilns under one tonne per day, mechanised units handling 1-15 tonnes per day, and industrial facilities above 15 tonnes per day. Each track has specific monitoring requirements, but eligibility and durability rules are uniform. Gold Standard has not yet announced when projects can begin registering under the methodology.
