How Much Do Carbon Offsets Cost in 2026?

Carbon offsets typically cost from a few pounds to £40+ per tonne of CO₂e in 2026, depending on project type, certification, vintage and co-benefits. Renewable-energy credits sit at the low end; nature-based removal and Gold Standard projects with strong community benefits command premiums. There is no single “price of carbon” — you are buying a specific project's tonnes.

What drives the price

• Project type. Avoidance (renewables, cookstoves) is usually cheaper than removal (reforestation, afforestation), and engineered removals are far more expensive again.
• Standard. Gold Standard's mandatory SDG co-benefits typically price above comparable Verra credits.
• Vintage. Recent vintages generally cost more than older ones, because buyers increasingly discount credits issued under superseded methodologies.
• Co-benefits & location. Jobs, health, biodiversity and high-demand geographies all add premium.
• Volume. Larger purchases improve per-tonne pricing, though rarely as much as buyers expect below a few thousand tonnes.

Why the range is so wide

The spread between the cheapest and most expensive tonne is more than a hundredfold, and it is not a market failure — it reflects genuinely different products sharing a single unit of account. A tonne avoided by a renewable project that was probably going to be built anyway, a tonne removed by a forest that must now be protected for decades, and a tonne captured and stored geologically are all “one tonne” on paper, and nothing alike in cost of production.

Very roughly, and treating any published range with caution because prices move:

• Low single-digit pounds — older-vintage avoidance credits, typically renewables. Cheap, legitimate, and the weakest story to tell your stakeholders.
• Roughly £5–£20 — the broad middle: cookstoves, forest protection, community projects, recent vintages.
• £20–£40+ — nature-based removals, strong verified co-benefits, premium standards and geographies.
• Far higher — engineered removals such as direct air capture, generally bought by companies with specific durability commitments.

The cheap-credit trap

A price well below the going rate for that project type is not a bargain; it is a question. Usually the answer is an old vintage, a superseded methodology, a project type whose baselines have been challenged, or — worst case — no registry at all. The cost of a credit you cannot evidence is not the price you paid; it is the cost of retracting the claim later. See are carbon offsets greenwashing? for how those retractions play out.

Budgeting it properly

Start from your measured tonnes (use the CO₂ calculator), decide the split between avoidance and removal, and price the portfolio rather than hunting for a single number. A workable approach for a first programme:

1. Measure the footprint and identify what you can genuinely reduce this year.
2. Decide the residual tonnage you intend to compensate.
3. Choose a mix — for example a majority of mid-range credits with a deliberate share of removals, increasing that share over time.
4. Get quotes per project and standard, not a blended headline rate.
5. Budget the reporting time as well as the credits — someone has to file the documentation.

One planning note that catches people out: if your emissions repeat annually, so does the cost. A one-off purchase buys a one-off claim.

What you get with Evertreen

Evertreen quotes per project and standard — Verra and Gold Standard — retires credits in your name with documentation, and can blend in geolocated tree planting from £1.5 per tree for visible, growing removal alongside the audited tonnes.

That combination is usually the best value per pound of communication as well as per tonne: the credits balance the books, the trees give your staff and customers something to look at. The trade-off is set out in tree planting vs carbon offsets, and supplier due diligence in how to choose a carbon offset provider.

Frequently asked questions

How much does 1 tonne of CO₂ offset cost? Commonly from a few pounds for avoidance projects to £40+ for premium removal and co-benefit projects. Project type, standard and vintage decide the figure.

Why are some credits so cheap? Lower-cost project types and older vintages, which is legitimate — or missing certification, which is a red flag. Ask which one applies before you buy.

Are prices rising or falling? They move with demand, scrutiny and supply, and the market has become two-tier: high-integrity removals and premium co-benefit credits hold their value, while questioned project types have fallen. Budget against the tier you intend to buy.

What does it cost to offset a flight? A long-haul return trip of roughly 2–3 tonnes per passenger costs somewhere between a modest and a meaningful sum depending entirely on the credit type you choose — the tonnage is the easy part, the quality decision is not.

Is tree planting cheaper than buying credits? They are different products. Trees, from £1.5 each with Evertreen, build long-term removal and engagement; credits deliver audited tonnes now. Many businesses budget both.

Should I buy the cheapest credits available? Only if you can evidence them. Optimise for what survives an audit, then for price within that set.

Do I need to buy every year? If the emissions recur, yes. A single purchase covers a single year's residual tonnes, and multi-year commitments often price better.
