The EU emissions trading system has decarbonised covered industry by more than 30% while its output grew by more than 60%.

Omissions

• The claimed '>60% output growth' figure could not be verified for ETS-covered industry in any source found. The comparable well-known EU figure is that the EU economy (GDP) grew by roughly 60% since 1990 — a different entity, scope and period from the ETS emissions cut, which begins in 2005.
• The confirmed decline in ETS stationary-installation emissions (about 51% between 2005 and 2024) is explicitly 'largely driven by the decarbonisation of the power sector', so attributing a '>30% decarbonisation' to industry specifically is not clearly supported by the sources found.
• Causal attribution is debated: peer-reviewed and think-tank analyses estimate the ETS's causal effect on emissions at roughly 14–16% relative to a no-policy counterfactual — lower than the raw emissions decline, which also reflects other factors.
• No single source was found stating both figures together; the two numbers appear to combine different metrics and reference periods.
