Decarbonisation UK Business

Decarbonisation UK business is governed by the framework set out in the UK Industrial Decarbonisation Strategy published by DESNZ, the UK Emissions Trading Scheme (ETS) operated by the Environment Agency, and the Climate Change Levy administered by HMRC. The Climate Change Committee provides the statutory monitoring under the Climate Change Act 2008, with annual progress reports identifying the compliance gap between planned and actual emissions trajectories. Heavy industry accounts for a meaningful share of UK emissions per DESNZ data, with the Industrial Energy Transformation Fund (IETF) providing the grant funding stream for capital investment in decarbonisation projects.

The UK Industrial Decarbonisation Strategy sets the policy framework

The UK Industrial Decarbonisation Strategy, published by DESNZ (formerly BEIS), sets out the policy framework for reducing UK industrial emissions by 2035 and reaching the legislated 2050 net zero target. The strategy covers the heavy industry sectors most challenging to decarbonise (cement, steel, chemicals, refining, glass), the carbon capture, usage and storage (CCUS) clusters being developed, and the hydrogen economy roadmap. The strategy is supported by the IETF grant scheme, the Industrial Clusters Mission, and the broader Net Zero Strategy. The Climate Change Committee provides independent monitoring of progress under the Climate Change Act 2008.

The strategy places policy emphasis on demand-side measures (energy efficiency, materials substitution), supply-side measures (low-carbon energy, electrification, hydrogen), and removals (carbon capture, nature-based solutions). The DESNZ Energy Trends publication provides the quarterly data on UK energy use and emissions intensity by sector, with the data feeding into Climate Change Committee progress assessments.

The UK ETS is the primary carbon pricing mechanism

The UK Emissions Trading Scheme is the UK's primary carbon pricing mechanism, operated by the Environment Agency on behalf of the four UK administrations under the Greenhouse Gas Emissions Trading Scheme Order 2020. The scheme covers electricity generation, aviation, and energy-intensive industrial installations above the relevant emissions thresholds. Operators must hold allowances equal to their reported annual emissions, with the cap on allowances reducing over time to drive the decarbonisation trajectory. The UK ETS replaced UK participation in the EU ETS following the EU exit and is broadly aligned with the EU ETS in scope and design.

The UK ETS auctions allowances regularly, with the auction price providing the operational carbon price for affected sectors. The Environment Agency publishes the annual scheme reports covering verified emissions, allowance allocations, and surrendered allowances. The Authority (the joint body representing the four UK administrations) sets the policy framework for the scheme, including the cap trajectory.

The Climate Change Levy taxes industrial energy use

The Climate Change Levy (CCL) is an HMRC-administered tax on industrial and commercial energy use, applying to gas, electricity, LPG, and solid fuels supplied to non-domestic users. The mechanism is set out in Schedule 6 of Finance Act 2000 and HMRC CCL guidance. The CCL operates alongside the UK ETS, with installations within the ETS scope having a different CCL treatment to those outside. Energy-intensive industries can secure reduced CCL rates through Climate Change Agreements (CCAs), which require commitments to specific energy efficiency improvements in exchange for the reduced rates.

The CCL rates are set annually and published in HMRC's rates and thresholds publication. The mechanism predates the UK ETS and continues to apply alongside it, providing a baseline carbon price signal for sectors not covered by the ETS. HMRC compliance activity in this area focuses on accurate measurement and reporting of taxable energy supplies.

The Industrial Energy Transformation Fund supports capex investment

The Industrial Energy Transformation Fund (IETF) provides grant funding for industrial energy efficiency and decarbonisation projects in qualifying sectors, with the funding administered by DESNZ. The fund operates through competitive phases, with each phase having specific eligibility criteria, sector focus, and total funding allocation. The qualifying sectors include cement, steel, chemicals, glass, ceramics, food and drink, and other energy-intensive industries. The fund covers feasibility studies, engineering studies, and capital deployment, with grant rates varying by phase and project type.

The IETF sits alongside the wider DESNZ funding landscape, including the Net Zero Hydrogen Fund, the CCUS Infrastructure Fund, and the Industrial Decarbonisation Challenge funded through UKRI. The funds collectively provide the public capital intended to unlock private investment in industrial decarbonisation infrastructure, with the OBR scoring the cost in its forecasts.

The ETS2 expansion will broaden carbon pricing scope

The UK ETS Authority has consulted on the expansion of the ETS to cover additional sectors, including waste incineration and certain non-CO2 greenhouse gases, broadening the scope of carbon pricing in the UK economy. The expansion mirrors developments in the EU, where the EU ETS2 is being introduced to cover buildings, road transport, and small industry. The UK consultation process and the eventual scope of expansion are central to the medium-term decarbonisation framework. The Environment Agency and the Authority have published consultation responses and policy statements on the expansion timeline.

Waste incineration is the most material early addition under consideration, given the rising volume of UK waste incineration capacity and the associated emissions profile. The scheme expansion would bring incineration operators into the carbon pricing framework, with structural implications for the waste sector and the broader circular economy framework.

The Climate Change Committee tracks the compliance gap

The Climate Change Committee (CCC) is the statutory independent advisor under the Climate Change Act 2008, with the remit to assess progress against the legislated carbon budgets and the 2050 net zero target through annual progress reports. The CCC's Progress Report to Parliament identifies the compliance gap between the planned emissions trajectory and the policies in place, sector by sector. The reports have consistently identified policy gaps in the industrial decarbonisation framework, particularly around clarity on the CCUS deployment pathway, the hydrogen production roadmap, and the demand-side measures needed to deliver the cement, steel, and chemicals transition.

The CCC's assessments are non-binding on government, but the Climate Change Act 2008 requires government to respond to the CCC's recommendations through annual policy statements. The compliance gap is the central metric for assessing whether existing policy commitments will deliver the legislated targets, with the OBR using the CCC framework in its fiscal risk reports.

Carbon Border Adjustment Mechanism will reshape UK ETS interaction with trade

The UK has consulted on the introduction of a Carbon Border Adjustment Mechanism (CBAM), aligned with the EU CBAM, to apply a carbon price equivalent on imports of carbon-intensive goods from jurisdictions with weaker carbon pricing. The UK CBAM would cover the same products as the EU CBAM in its initial scope (cement, iron and steel, aluminium, fertilisers, hydrogen, electricity), with effective implementation announced for January 2027. The mechanism is intended to prevent carbon leakage as the UK ETS cap tightens. The Treasury consultation responses and the eventual legislation will set the operational rules.

The CBAM has been politically contentious because of its trade implications. UK manufacturers welcomed the level playing field it provides against imports from lower-cost jurisdictions, while importers raised concerns about the administrative burden and the compatibility with WTO rules. The Treasury Committee has heard evidence on the design choices.

What is decarbonisation UK business policy?

UK industrial decarbonisation policy is set out in the DESNZ Industrial Decarbonisation Strategy, the UK Net Zero Strategy, and the legislated 2050 net zero target under the Climate Change Act 2008. The operational levers are the UK ETS, the Climate Change Levy, sector-specific grant funding (IETF, NZHF, CIF), and the Climate Change Agreements framework.

What is the UK industrial decarbonisation framework?

The framework combines carbon pricing (UK ETS, CCL), grant funding (IETF and related schemes), regulation (carbon reporting under SECR, CBAM at the border), and statutory monitoring (Climate Change Committee). The Climate Change Act 2008 provides the legislated targets and the statutory monitoring infrastructure.

How does the business decarbonisation strategy connect to net zero?

The UK Industrial Decarbonisation Strategy is the sector-specific policy framework for reducing industrial emissions on the trajectory to net zero by 2050. Industrial emissions are one of the harder-to-abate sectors, with the strategy focused on CCUS, hydrogen, and electrification as the main supply-side levers and energy efficiency and materials substitution as the demand-side levers.

What is the net zero business strategy at sector level?

Sector-level net zero business strategies are typically based on the Streamlined Energy and Carbon Reporting (SECR) framework for large UK companies, the TCFD recommendations adopted by FCA-regulated entities, and the broader sustainability disclosure requirements being phased in by Treasury. The Climate Change Committee's sectoral analyses provide the policy benchmark for assessing private sector strategies.

What is the Climate Change Levy?

The Climate Change Levy is an HMRC-administered tax on industrial and commercial energy use, applying to gas, electricity, LPG, and solid fuels supplied to non-domestic users. The rates are set annually. Reduced rates are available for energy-intensive industries through Climate Change Agreements (CCAs).

What is the UK ETS coverage?

The UK ETS covers electricity generation, aviation operators, and energy-intensive industrial installations above the relevant emissions thresholds. Operators must hold allowances equal to their reported annual emissions. The cap on allowances reduces over time to drive the decarbonisation trajectory, with the Environment Agency administering the scheme.
