Carbon prices are not one market. A regulated EU allowance, a UK ETS (UK Emissions Trading Scheme) allowance, a CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation) eligible emissions unit and a voluntary biochar removal credit can all be described as "carbon prices", but they mean different things. Use this guide to separate the main price signals, read them correctly, and choose the right next explainer.
Carbon credit ranges, CORSIA eligibility and ETS allowance prices move over time, so old figures can quickly become misleading. Treat the price map below as a starting point and check current market quotes before making procurement or investment decisions.
Indicative voluntary carbon credit guide via The Carbon Workbench. Always check current market quotes before making procurement or investment decisions.
Carbon price map
The first step is to separate allowance prices from credit prices. Allowances are usually part of a regulated cap-and-trade system. Credits are project-based units issued for emissions reductions, avoidance or removals. They are not automatically interchangeable.
| Price signal | What it represents | Who uses it | Best Planet Brief guide |
|---|---|---|---|
| Voluntary carbon credits | Project-based credits from avoidance, reduction or removal projects. | Companies, brokers, climate contribution buyers and sustainability teams. | Carbon credit prices in 2026 |
| EU ETS (European Union Emissions Trading System) allowances | Regulated allowances used by covered European emitters under cap-and-trade. | Power, industry, aviation, analysts and compliance teams. | EU ETS explained |
| UK ETS allowances | Regulated UK carbon allowances used by covered UK installations and sectors. | UK compliance teams, industrial firms and policy watchers. | EU ETS vs UK ETS |
| CORSIA eligible units | Carbon units that may be eligible for aviation compliance under ICAO (International Civil Aviation Organization) rules. | Airlines, brokers, project developers and aviation market analysts. | CORSIA credit prices |
| Internal carbon prices | Prices companies use internally for budgets, investment appraisal or shadow pricing. | Finance, sustainability, procurement and strategy teams. | Business offsetting guide |
Why there is no single carbon price
Carbon pricing is a family of markets and policy tools. The EU ETS price is created by a regulated cap on emissions and allowance supply. A voluntary carbon credit price is shaped by project type, standard, vintage, buyer trust and the claim a buyer wants to make. A CORSIA eligible unit price is shaped by aviation-specific eligibility rules and demand from airlines.
This is why headline comparisons can mislead. A cheap voluntary credit may not be low-quality, but low price should trigger more due diligence. A high-priced engineered removal may offer durability, but it may not suit every buyer or budget. A regulated allowance price can be useful context, but it is not a replacement for a voluntary credit price.
Voluntary credit price bands
Voluntary carbon credits are usually priced by project type and perceived quality rather than by one central exchange price. The ranges below are directional categories, not live quotes. Use them to understand why buyers can see such different prices for something that is still described as one tonne of carbon dioxide equivalent.
| Segment | Typical project types | Why prices differ | Buyer caution |
|---|---|---|---|
| Low-cost avoidance | Some renewable energy, REDD+ (reducing emissions from deforestation and forest degradation) and older vintages. | Large supply, older methodologies, buyer scrutiny and lower perceived scarcity. | Check additionality, baseline assumptions, vintage and claims language carefully. |
| Higher-quality avoidance and reduction | Cookstoves, methane capture, efficient appliances and some community projects. | Co-benefits, monitoring evidence, health outcomes and stronger buyer demand. | Ask for project documentation, monitoring reports and retirement evidence. |
| Nature-based removals | Reforestation, afforestation, improved forest management and some blue carbon. | Removal value, land constraints, permanence risk and biodiversity value. | Check buffer pools, reversal risk, land rights and long-term monitoring. |
| Engineered removals | Biochar, enhanced weathering and direct air capture. | Durability, scarcity, measurement confidence and early-stage supply. | Check delivery risk, methodology maturity and whether the tonne has been issued or is only contracted. |
| CORSIA-linked supply | Eligible emissions units approved for a relevant CORSIA phase. | Eligibility rules, programme approval, host-country authorisation and airline demand. | Do not assume a normal voluntary credit is CORSIA eligible. |
How to use this guide
For a quick price sense, start with the embedded Carbon Workbench guide above. For procurement or public claims, use the deeper guides. A buyer should understand the unit type, project type, standard, vintage, registry record, retirement status and the claim the unit will support before treating the price as meaningful.

Buyer checklist before relying on a price
- Is the unit an allowance, a voluntary credit, a CORSIA eligible emissions unit or an internal shadow price?
- Is the credit a reduction, avoidance or removal?
- Which standard, methodology and registry issued it?
- What is the vintage, and does it match the reporting or claim period?
- Is the price for issued units, forward delivery or an indicative broker quote?
- Does the quote include retirement, registry fees, due diligence or transaction costs?
- Is the unit suitable for the public claim being made?
- Has the data been reviewed recently enough for the decision being made?
Update cadence
Carbon price context changes quickly. The figures and references on this page should be checked regularly, especially when there are major CORSIA eligibility decisions, ETS policy updates or material changes in voluntary carbon market pricing.
For future automation, the ideal setup is a small scheduled job that checks source pages, records the latest review date, flags stale sections and updates a simple "last reviewed" note when the page has been checked.

Bottom line
A carbon price only makes sense when you know the market, unit type, rules and claim behind it. Use the price map above, then follow the linked explainers to test whether the quoted tonne is credible, current and suitable for the decision you are making.
