How the estimates were built: data sources, modelling approach and validation steps.
Research approach
A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.
The size was built upward from the tonnes of allowances auctioned and traded under each national and regional emissions trading system, the tonnes of voluntary and mechanism credits issued and retired on registries, and the realised price per tonne by instrument and project type. Exchange volumes, auction clearing prices and over-the-counter premiums were applied to each tonne to give value by market type, region and channel. The build was then compared with disclosed trading, compliance-cost and offset-purchase figures from listed energy groups, exchanges and corporate buyers. Where the two disagreed, the volume or price assumption in the build was corrected; the disclosed figures were not averaged into the estimate. The inputs that move the result most are auction volumes, secondary-market allowance prices, retirement volumes by vintage and the discount on lower-integrity credits.
The four stages
The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.
What the build rests on, and what checks it
The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.
- Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
- Realised pricing by tier and channel, rather than one blended average applied across the whole market
- Take-up and frequency: how much of the addressable base buys, and how often it repeats
- Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
- Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
- Trade and customs flows, where the product crosses borders in a separately recorded form
Data sources
Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.
- Commercial and product leadership at the companies that supply the market
- Procurement and specification leads at the organisations that buy it
- Distributors, integrators and channel partners, where the market is served indirectly
- Regulatory and standards specialists, where approval governs what can be sold at all
- Company filings, annual reports and investor disclosure
- Government statistics, customs records and regulatory registers
- Trade association output and standards-body publications
- Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Discussions targeted the roles that set or observe prices and volumes: compliance and sustainability heads at regulated emitters, carbon trading desk managers at energy and commodity companies, project developers, registry and verification body representatives, brokers and exchange staff, and procurement leads at corporate buyers of offsets and removals. Sampling emphasised Europe, where the deepest allowance market sits, and Asia Pacific, where national trading systems are expanding, with added coverage of North America and of host countries for mechanism-based credits in Latin America, Africa and Southeast Asia. The discussions were used to test price assumptions, pipeline volumes and expectations on policy timing; they did not supply the estimate itself.
Desk research rested on registry and auction data: the European Union Transaction Log and EU ETS auction results published through the European Energy Exchange, UK ETS auction notices, the joint California and Quebec auction results, RGGI auction reports, China national ETS trading data from the Shanghai Environment and Energy Exchange, and the Korea Exchange emissions market. Voluntary supply was drawn from the issuance and retirement records of the Verra Registry, the Gold Standard Impact Registry, the American Carbon Registry, the Climate Action Reserve and Puro.earth. Policy sources included Paris Agreement Article 6 supervisory body documents, the EU CBAM regulation and ICAO CORSIA decisions, alongside annual reports and sustainability disclosures of listed buyers and traders.
Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.
Forecasting
The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.
The forecast is built by projecting traded volumes and realised prices separately for each market type. Allowance volumes follow announced caps, the phase-out of free allocation and the entry of new sectors and countries; prices follow marginal abatement cost and scheduled cap reductions. Voluntary and mechanism volumes follow project pipelines, corporate purchasing commitments and the pace at which host countries authorise transfers. Pricing for lower-integrity credits is normalised for the drop in demand seen after quality concerns surfaced. For the forecast to hold, major systems must tighten on schedule, new national systems must launch in the years planned, and quality standards must stabilise so that buyers return to the voluntary market.
Triangulation and validation
No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.
Outputs were back-tested against recorded traded value growth for the historical years, and the model was checked for whether it reproduces the direction of the post-2022 voluntary slowdown alongside the rise in allowance values over the same period. Segment shifts, such as the move toward removals and toward Asia Pacific, were reviewed with experts who work in trading and project development. Sensitivities were run on allowance price paths, issuance timing for mechanism credits, the pace of free allocation phase-out and the share of retired credits that meet integrity benchmarks. Each regional and segment series was confirmed to sum to the scope total in the base and final years.
Confidence and limitations
Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.
Estimates are firmest for compliance allowances in Europe, North America and China, where auction results and exchange volumes are public. They are weaker for over-the-counter voluntary trades, where prices are rarely disclosed, and for forward and offtake arrangements, which are privately contracted. Mechanism-based credits and tokenized instruments rest on thin reporting and early rules, so their ranges are wide. Structural risks that would force a revision include a change in EU or Chinese cap trajectories, delays in host-country authorisation, and a loss of buyer confidence in credit quality. A band of ten to fifteen percent around the base-year total is reasonable.
