Summary
Details
- Denmark
Legally binding for:
Businesses using taxable fuels and process energy are subject to CO2 taxation rules.
Non-ETS industrial emitters and energy users where carbon pricing is applied via taxes rather than allowances.
Certain uses may be excluded or treated differently (for example, space heating and district heating treatment differ from process uses in some frameworks).
Transitional compensation, deductions, or relief mechanisms may apply depending on sector, use and policy design.
ETS-covered emissions are generally handled through allowance compliance rather than a parallel full CO2 tax, but boundary rules must be tested carefully.

What’s Required
Denmark’s Green Tax Reform increases carbon pricing pressure through corporate CO2 taxation, particularly for emissions outside the EU ETS and certain fuels used in industrial processes.
Key requirements include:
Payment of CO2-related taxes on relevant fuels and processes, with rates that increase gradually toward 2030.
Differentiation between ETS-covered activities and non-ETS activities, with separate compliance logic depending on coverage.
Reporting and documentation duties tied to tax calculation bases (fuel use, process use, emissions factors, and eligible deductions/reliefs).
Mechanisms may include compensation, transitional arrangements, and targeted incentives (for example, support or tax treatment linked to carbon capture investments).
Important Deadlines
From 2025: CO2 tax changes begin applying to covered fuels/processes for in-scope businesses.
2025–2030: phased increases and evolving rules require annual review of tax position, relief eligibility, and documentation readiness.
Ongoing: maintain records to support tax reporting and withstand audits.
Current Status
Green tax reform measures are active policy instruments and continue to shape Denmark’s pathway toward meeting national climate targets, with a multi-year implementation horizon.
Penalties for Non-Compliance
Tax reassessments, interest, and administrative penalties for underpayment or incorrect reporting.
Increased audit exposure when documentation of fuel use categorisation and eligibility for relief is weak.
Potential reputational risk where tax non-compliance overlaps with climate claims or reporting commitments.
Examples of Known Violations
Misclassification of fuel use to obtain a lower CO2 tax burden.
Claiming relief or deductions without evidence or eligibility.
Underreporting taxable consumption due to weak metering or allocation controls.
