Buying carbon credits used to mean phoning a broker and hoping for the best. In 2026 the process is far more transparent — if you know the route. Here’s how to buy carbon credits properly, whether you need one tonne or one hundred thousand.
Step 1: Know what you’re offsetting
Measure before you buy. Businesses should quantify Scope 1 and 2 emissions (and ideally material Scope 3); individuals can use a reputable footprint calculator. You can’t buy the right amount of anything until you know the number, and serious buyers reduce what they can first — credits are for what remains.
Step 2: Choose your route to market
Retail marketplaces suit small buyers: platforms list verified projects, show prices per tonne, and retire credits in your name at checkout. Brokers and traders suit mid-size purchases, sourcing credits to a quality spec and negotiating price. Direct deals with project developers suit large corporates — often multi-year offtake agreements that fund projects upfront in exchange for future credits at a fixed price. Exchanges offer standardized contracts for institutional volumes.
Step 3: Set your quality bar
This is where buyers get burned. Insist on: a recognised standard (Verra, Gold Standard, or an ICVCM-approved methodology); an independent rating (agencies now score projects the way Moody’s scores bonds); a recent vintage; and clear treatment of additionality and permanence. Decide your mix of avoidance credits (cheaper, fund conservation) and removals (pricier, increasingly required for credible net-zero claims).
Step 4: Expect these prices
In 2026, budget roughly: $6 for average REDD+ avoidance credits, $22 for reforestation, $25–80 blended per tonne for a quality corporate portfolio, $177 for biochar, and $500+ for direct air capture. If a seller offers “verified” credits at $2, the discount is telling you something.
Step 5: Retire and document
A purchase means nothing until the credit is retired — permanently cancelled in the registry with your name on the retirement record. Get the serial numbers and the registry link. That record is your proof for auditors, customers, and regulators, and it’s the difference between offsetting and simply owning paper.
Common mistakes to avoid
Buying on price alone; treating credits as a substitute for cutting emissions; claiming carbon neutrality on unretired credits; ignoring vintage; and buying from resellers who won’t disclose the underlying project. Every one of these has produced a public greenwashing story — don’t join the list.
The bottom line
Buying carbon credits well is a procurement discipline like any other: define the spec, vet the supplier, verify delivery. Do those three things and your money funds real climate work.
