Understanding carbon markets in 2026: what buyers need to know
The argument about whether to buy carbon credits is largely settled. The argument about what counts as a credible credit is not — and in 2026 that distinction is where most of the value sits.
By Terra Verde
Carbon markets entered 2026 with a quieter problem than the one that dominated the previous five years. Scandal and integrity questions no longer stop corporates from participating; they now decide which credits those corporates are willing to touch, and at what price.
Two markets have emerged
The voluntary market has split in two. High-integrity avoidance credits from established methodologies still clear at modest prices. Removals, and anything carrying a strong integrity label, trade at a significant premium and often on multi-year contracts rather than spot.
For a buyer, that means the credit is no longer the whole product. Delivery certainty, methodology durability and the credibility of the project developer are now priced in.
Article 6 is now operational, not theoretical
Bilateral agreements under Article 6 of the Paris Agreement have moved from signing ceremonies to implementation. For African projects this matters in two ways:
- Corresponding adjustments create a second, compliance-grade route to market.
- Host-country authorisation becomes a live approval process with its own political economy.
A project that could sell into the voluntary market in 2022 may need a different legal structure to sell under Article 6 today. Buyers are asking for the authorisation trail, not just the registry entry.
What credible buyers actually ask
In diligence, the questions we see most often are unglamorous:
- Who holds the land rights, and for how long does the carbon right run?
- How was additionality demonstrated, and what happens if the counterfactual changes?
- What share of revenue reaches the communities who protect the resource?
- What is the leakage story across the surrounding landscape?
- Who verified, under which standard, and what were the findings?
None of those questions is answered by a broker's one-page summary. They require project documentation that was written to survive scrutiny.
The implication for African supply
Zimbabwe and its neighbours sit on substantial nature-based supply that the market has largely under-served, because the hard part is not the carbon — it is the measurement, the tenure and the benefit-sharing.
Developers who invest in those three things are now being rewarded with contracts. Those who treat them as paperwork are finding the market closed to them.
If you are buying, the discipline is to ask the unglamorous questions before the price conversation. If you are developing, the discipline is to build the answers before anyone asks.
