Carbon credits for what’s technically the same unit — one tonne of CO₂e — can sell anywhere from a couple of dollars to several hundred. That range confuses a lot of first-time buyers, but the price differences track real, identifiable factors, not just marketing.
Project Type Drives Most of the Spread
The single biggest driver of price is whether a credit represents avoidance or removal. Avoidance credits (methane capture, renewable energy, forest protection) tend to be cheaper because the underlying projects are more established and higher-volume. Removal credits (reforestation, soil carbon sequestration, direct air capture) tend to be significantly more expensive, because the technology and project types are newer, lower-supply, and in some cases still capital-intensive to build out. Direct air capture in particular can run into the hundreds of dollars per tonne, reflecting its early-stage cost curve.
Certification Standard and Vintage
Credits certified by different standards — Verra, Gold Standard, Climate Action Reserve, Puro.earth — aren’t perfectly interchangeable in the market. Gold Standard credits, for instance, often carry a premium because the standard requires demonstrated co-benefits beyond carbon, such as biodiversity or community impact. A credit’s “vintage” (the year the emission reduction actually occurred) also affects price — more recent vintages typically sell at a premium over older ones sitting unsold in a registry.
Retail vs. Wholesale Markets
Buying a single credit through a retail platform costs more per tonne than buying in bulk on the wholesale/institutional market, where large buyers negotiate directly with project developers or brokers. Retail pricing bundles in the cost of verification, portfolio curation, retirement processing, and customer-facing infrastructure — the same reason a bag of coffee costs more per cup at a café than buying beans wholesale.
Co-Benefits Add a Premium
Projects that deliver measurable benefits beyond carbon — clean cookstoves that also reduce indoor air pollution, forest projects that support local community livelihoods, or projects verified against the UN Sustainable Development Goals — often command higher prices than a bare-minimum carbon-only project, because buyers are effectively paying for the additional verified impact.
What This Means When You’re Buying
Price alone isn’t a reliable signal of quality, but unusually cheap credits are worth double-checking — extremely low prices often mean avoidance-only, lower-scrutiny projects, or in some cases, credits from a registry with weaker verification standards. The more useful question isn’t “is this expensive or cheap” but “what specifically does this price include” — which registry, which project type, and whether retirement is handled and documented.
Coffset’s carbon footprint calculator shows the tonnage you need to offset, and credits purchased through Coffset are priced against a curated, Verra- and Gold Standard-certified portfolio, with the retirement and serial number included rather than sold separately.
