Capital Formation and Risk SharingTAX CREDITS AND REDUCTIONS
Lever last updated: 10 September 2026
Tax relief that rewards investment in, production of, or purchase of carbon removal.
Cost
Low to Very high
Government bears forgone revenue, refunds and administration. At an illustrative EUR200 per tonne, a 25,000-tonne production credit costs EUR5 million yearly, while ten million tonnes cost EUR2 billion.
Complexity
Low to High
A local authority can amend an existing tax reduction, while a national CDR credit may require legislation, technical eligibility, joint project review, import rules, claim systems, audits, repayment and coordination between tax and climate authorities.
Timeline
Short to Medium
From formal initiation, legislation, tax guidance and removal-verification rules may take two to five years. Investment credits can then influence financing immediately, whereas production credits change cash flow only after verified removals begin.

Overview
Governments can use tax credits to reward businesses that invest in CDR, deliver verified removals or purchase them. An investment credit covers part of eligible project costs, while a production credit pays a set amount for each verified net tonne. Credits may be refundable, paying cash when they exceed the claimant’s tax bill, or transferable, allowing sale to another taxpayer. These options can reduce construction costs, add operating revenue or stimulate purchases. Unlike grants, support is claimed through the tax system. Accelerated depreciation is covered separately because it changes when equipment costs are deducted rather than awarding a credit.
Key Considerations
Choosing between investment and production credits determines when support arrives and what it rewards. Investment credits reduce construction costs but may support equipment that never removes carbon. Production credits reward verified tonnes but provide no money while projects are built. The rate, duration, spending limit and refund or transfer rules determine which companies benefit and the public cost. Eligibility should require net removal from atmospheric or sustainable biogenic carbon, a stated storage period and repayment if stored carbon is released. Claims require project approval, evidence, audits, treatment of imports and other subsidies, and a phase-out that investors can anticipate.
Opportunities
Investment credits can reduce the capital developers must raise, while production credits can provide income for each verified tonne and buyer credits can make removals cheaper to purchase. Refundable credits can reach young companies with little tax to pay, while transferable credits can turn future tax benefits into earlier cash. Stable incentives can make projects easier to finance, broaden participation beyond established profitable firms and support repeated deployment. Greater deployment may generate learning and lower costs, but tax support does not guarantee either outcome.
Risks
An investment credit can pay for equipment that produces few removals, while a generous production credit can overpay low-cost projects. Broad eligibility may support fossil carbon capture or enhanced oil recovery, which can reduce emissions but does not remove atmospheric CO₂. Non-refundable credits may not help young firms. Sold credits often fetch less than face value. Uncapped schemes can create public costs, while abrupt repeal can strand investments made in reliance on the incentive.
Monitoring and Evaluation
Tax and climate authorities should compare public cost with new investment, operating projects and verified net removals that would not have occurred without the credit. They should examine who receives support, how much value developers lose when selling credits, failed projects, reversals and improper claims. The findings should guide changes to rates, refundability, eligibility, caps, phase-out dates and audit effort.
Stakeholder Engagement
Engagement should test whether the incentive changes investment and whether claims can be audited. Developers, suppliers and lenders explain costs and financing. Finance ministries and tax authorities use evidence to set the spending limit and claims process. Climate agencies, scientists, registries and storage regulators define qualifying removals. Tax advisers test administration, while communities and civil society examine safeguards and distribution.
Governance Levels
Tax policy is usually controlled nationally, states and provinces with taxation authority can layer targeted incentives on top. In the EU, direct Union-wide tax credits collide with national fiscal sovereignty, so the supranational role is guidance and state-aid approval rather than the credit itself.
Implementation Strategies
Governments should first choose whether to reward equipment investment or verified removals and identify the taxpayers whose decisions should change.
They should define qualifying carbon sources, lifecycle accounting, storage duration, verification and repayment after reversal.
Credit rates, refundability, transfer rules, spending caps, how credits combine with other subsidies and phase-out dates should then be set together.
Tax and climate authorities should connect claims to project records, publish results and adjust future terms when uptake, cost or integrity diverges from expectations.
Include a sunset or review clause to adjust the credit value based on market response and technology cost changes over time.
Case Studies

Belgium’s Thematic Investment Deduction
Belgium’s reformed investment deduction applies to qualifying assets acquired from 1 January 2025. It reduces taxable profit by an additional 40 per cent of investment cost for small companies and 30 per cent for larger companies in 2025, rising to 40 per cent from tax year 2027. The official environmental list covers capture, transport, permanent storage and permanent use of eligible industrial-process CO₂, including non-fossil CO₂ from biomethanisation. However, the required certificate process for this category remained unavailable in Flanders in August 2026.

United States Section 45Q tax credit
Section 45Q is an operational federal production credit. Congress expanded it in 2022, and the Internal Revenue Service now allows direct-air-capture facilities to claim USD36 for each tonne securely stored, multiplied by five when labour requirements are met. Some claimants can receive direct payment, while other businesses may transfer the credit for cash. The mechanism therefore adds income after carbon is captured and stored. The provision is not a dedicated CDR credit because fossil-source capture, carbon use and enhanced oil recovery also qualify.

Canada Carbon Capture, Utilization and Storage Investment Tax Credit
Canada's refundable investment credit became law in June 2024, following a 2021 proposal and consultation. Companies first submit a project plan for technical review, then claim approved equipment costs through their tax return. Current rates refund 60 per cent of eligible direct-air-capture equipment and lower shares for other capture, transport and storage equipment through 2035.

Colorado Industrial Clean Energy Tax Credit
Colorado enacted House Bill 23-1272 in May 2023 and made its refundable industrial credit available from tax year 2024. The law covers part of the capital cost of approved industrial improvements and expressly includes direct air capture and other carbon-removal systems. The Colorado Energy Office reserves credits after reviewing applications, and the revenue department pays any amount exceeding the claimant's tax bill. The law creates direct state-level CDR eligibility, but the wider programme covers many industrial technologies and no public evidence identifies a CDR award or delivered removal.
