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 is built upward from installed-base and order activity. For each product type, CDI estimates the equipment commissioned each year in power, cement, steel, chemicals and other emitting industries, the airflow capacity per installation, and the realised price per unit of capacity for each technology and configuration. Service revenue is added from retrofit cycles, filter and catalyst replacement intervals and monitoring contracts. The build is then checked against disclosed segment revenue of listed equipment suppliers and against customs data for filtration machinery and catalyst components. Where the two disagree, the unit volume or price assumption in the bottom-up build is corrected; the disclosed figures act as a check and are not averaged in.
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
Interviews target plant engineering and environmental managers at power, cement, steel and chemical sites, procurement leads who issue emission-control tenders, EPC contractors who specify and install systems, and regulatory consultants who advise on permit compliance. Supplier-side conversations cover product managers and regional sales heads at equipment makers and at component producers such as filter media and catalyst suppliers. Sampling emphasises Asia Pacific, where new industrial capacity is added fastest, North America and Europe, where retrofit and replacement demand dominates, and the Gulf region, where refining and petrochemical build-out drives orders.
Desk research rests on national emission standard registers, including the US EPA New Source Performance Standards, the Industrial Emissions Directive and its best available technique reference documents in the European Union, China's ultra-low emission standards for power and steel, and the Central Pollution Control Board norms in India. Trade flows are read from customs codes for filtering machinery (HS 8421) and catalysts. Company annual reports and filings provide segment revenue and order backlog, and industry association statistics on power, cement and steel capacity supply the demand base.
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 combines new industrial capacity additions by region, the schedule of emission limit tightening, and replacement cycles for installed equipment. Pricing follows input cost movements in steel, filter media and catalyst metals. Coal power decommissioning in mature markets is netted against growth in cement, steel, chemicals and waste-to-energy in developing economies. For the forecast to hold, enforcement of existing standards has to continue at its current intensity, permitting timelines must not lengthen sharply, and industrial investment must stay broadly on its present path. The historical base is normalised for retrofit surges that followed major standard changes.
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 growth in the historical years 2020 to 2024, checking that the modelled series reproduces the direction and rough magnitude of reported supplier revenue in those years. Segment shifts, such as the move toward multi-pollutant and catalytic systems, were reviewed with industry specialists. Sensitivities were run on regional capacity additions, the pace of standards tightening, steel and filter media input costs, and the split between retrofit and new installation. Segment, regional and country figures were reconciled to the scope total in the base year and in the last year of the forecast.
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.
The estimate is firmest for particulate control, scrubbers and fabric filters in power and cement, where supplier disclosure and installation records are fullest, and for North America and Europe. It is thinner for adsorption and thermal systems sold inside broader process packages, for mobile source equipment, and for countries that do not publish order data. A reasonable band around the base-year total is plus or minus 12 percent. Structural risks that would force a revision include delayed standards enforcement, faster closure of coal capacity than assumed, and a sharp swing in steel prices.
