Carbon credit tenders and RFPs
Public bodies buy carbon credits more often than most suppliers expect. National governments buy them to meet tax or compliance rules, regional governments retire them against their own operational emissions, and development agencies buy them on behalf of programmes that have promised a climate-neutral outcome. The notices are usually short and specific: a volume in tonnes, a vintage window, a standard such as Verra or Gold Standard, sometimes a project type or host region, and a delivery date for retirement in a named registry.
What separates a winning bid is rarely price alone. Buyers increasingly score the integrity of the credits: additionality, permanence, the risk of reversal, co-benefits, and whether the project carries a recognised quality label. Some notices ask for removal credits only, others for avoidance credits from a specific sector such as cookstoves or forestry. Read the eligibility section before the price schedule, because a perfectly priced offer of the wrong credit type is scored as non-compliant.
This page tracks open tenders whose own text mentions carbon credits or emission reduction credits, matched on the notice rather than on a sector label. Developers, brokers and retailers with inventory to sell, and advisers who help buyers write these specifications, are the readers it is built for.

Frequently asked
Who buys carbon credits through public tenders?
National and regional governments, public agencies offsetting their own operations, development agencies and multilateral programmes. Corporate buyers run private requests for proposals as well, but those are rarely published on public portals.
What does a carbon credit tender usually ask for?
A volume in tonnes of CO2 equivalent, an accepted standard and registry, a vintage range, sometimes a project type or host region, evidence of retirement, and a price per tonne. Many add quality criteria such as permanence, additionality and co-benefits.
Can a small project developer bid?
Often yes, if the volume is modest or the tender is split into lots. Where the volume is large, developers usually bid through a broker or a consortium that can aggregate supply and carry the delivery risk.
