UK Carbon Credit Sector Valued at £1.2 Billion

UK carbon pricing reform takes shape for 2027

The UK government has confirmed major changes to domestic carbon pricing that will reshape compliance costs and reporting duties for thousands of businesses. These reforms, scheduled for 2027, will merge the current UK Emissions Trading Scheme with a broader Carbon Border Adjustment Mechanism. For SMEs in manufacturing, logistics, and construction, the shift represents both a compliance challenge and a competitive pressure point.

Carbon pricing already affects around 1,000 UK installations directly. However, the planned expansion will pull in businesses through supply chain obligations and import duties. Companies that currently operate outside the regulated sphere will need to understand how these mechanisms work. More importantly, they will need to assess whether their cost base remains viable when carbon costs are embedded throughout their supplier network.

This development sits within a wider policy push towards net zero by 2050. The government sees carbon pricing as a market tool to drive emissions reductions without direct mandates. For businesses, the practical effect is that carbon becomes a line item in procurement decisions, tender evaluations, and long term investment planning. The commercial consequences are already visible in sectors like steel, cement, and chemicals, where European competitors face similar pressures.

How the 2027 carbon pricing changes will work

The UK Emissions Trading Scheme currently covers power generation, energy-intensive industries, and aviation. Installations receive or purchase allowances that permit them to emit one tonne of carbon dioxide equivalent per allowance. At the end of each compliance year, they must surrender enough allowances to cover their verified emissions. Prices fluctuate based on market demand, with recent trading showing allowances at around £40 to £50 per tonne.

From 2027, the government will introduce a Carbon Border Adjustment Mechanism alongside the existing scheme. This mechanism will apply carbon costs to imported goods from countries with weaker climate policies. The stated aim is to prevent carbon leakage, where production shifts to jurisdictions with lower environmental standards. In practice, this means importers will pay a charge based on the embedded emissions in products like steel, aluminium, cement, fertilizers, and hydrogen.

The European Union is implementing a similar system, with its Carbon Border Adjustment Mechanism beginning a transitional phase in October 2023. The UK version will likely follow comparable principles, requiring importers to declare emissions and purchase certificates to cover the carbon content of goods. Notably, the system will account for any carbon price already paid in the country of origin, avoiding double taxation. However, the administrative burden falls on UK importers, who must verify foreign emissions data and maintain detailed records.

For businesses, the timeline matters. The government has indicated that 2027 remains the target date, but detailed regulations are still being drafted. Transitional arrangements may apply, particularly for smaller importers or specific product categories. Businesses that import affected goods should begin assessing their exposure now, because supply chain adjustments take time. Similarly, UK exporters need to monitor how their products will be treated in the EU system, as differential treatment could affect competitiveness.

Direct cost impacts on manufacturing and logistics

Manufacturing businesses face the most immediate financial consequences. Companies that produce steel, cement, ceramics, glass, or chemicals already participate in the UK Emissions Trading Scheme. For them, the 2027 changes will tighten allowance allocations and reduce free permits. This shift increases direct costs, because businesses must purchase more allowances at market prices. A cement plant emitting 100,000 tonnes annually could see costs rise by several million pounds if free allocation drops by 50 percent.

Importers will feel the impact through the Carbon Border Adjustment Mechanism. Businesses bringing in steel beams, aluminium components, or cement from countries without comparable carbon pricing will pay a levy. The exact rate will depend on the embedded emissions and the carbon price in the UK market at the time. For construction firms that rely on imported materials, this adds a new variable cost that must be factored into project budgets and fixed price contracts.

Logistics and freight companies encounter indirect effects through fuel costs and supply chain complexity. While road transport fuel is not directly covered by the emissions trading scheme, hauliers will see cost increases from suppliers who are covered. Additionally, the administrative requirements for verifying emissions data on imported goods will add compliance work. Larger logistics providers may absorb this through existing systems, but smaller hauliers could struggle with the reporting burden.

The competitiveness question is particularly acute for businesses competing with European firms. If UK carbon prices diverge significantly from EU prices, cost differences will emerge. UK manufacturers exporting to the EU will need to navigate the EU Carbon Border Adjustment Mechanism, while EU manufacturers selling into the UK will face the UK system. Businesses operating in both markets will need to track two sets of rules, two sets of allowances, and two sets of reporting requirements.

New compliance and reporting obligations

Compliance with the expanded carbon pricing system requires verified emissions data. For installations already in the UK Emissions Trading Scheme, this is familiar territory. They must monitor emissions, submit annual reports, and have those reports verified by accredited bodies. The verification process follows strict standards and must be completed by independent auditors. However, the 2027 reforms will tighten the rules, particularly around free allocation and reporting deadlines.

Importers face a new compliance landscape entirely. Under the Carbon Border Adjustment Mechanism, they must declare the embedded emissions in imported goods. This requires obtaining emissions data from foreign suppliers, which can be difficult if those suppliers do not already track carbon footprints. Default values may be available for businesses that cannot obtain actual data, but defaults are typically set conservatively high, resulting in higher charges.

The reporting burden extends beyond annual returns. Importers will need systems to track shipments, verify emissions data, and purchase border adjustment certificates. These systems must integrate with customs processes, because declarations will be required at the point of import. For SMEs that import occasionally, this could mean hiring specialists or using third party services. For larger importers, it means investing in software and training staff to manage the process.

Penalties for non-compliance will mirror those in the existing emissions trading scheme. Businesses that fail to surrender sufficient allowances face fines of at least twice the market price per tonne of excess emissions. In addition, they must still purchase the required allowances, so non-compliance does not avoid the cost. For importers, failure to declare emissions accurately or purchase border adjustment certificates will likely result in similar financial penalties plus potential customs delays.

Carbon pricing developments affecting UK businesses

The UK Emissions Trading Scheme and Carbon Border Adjustment Mechanism will merge existing installations with new import obligations from 2027. Businesses in manufacturing, logistics, and construction should assess their exposure now. Importers must prepare for emissions verification and certificate purchases. UK manufacturers will see reduced free allowances and higher direct costs. Compliance systems need to track verified emissions data and integrate with customs processes. Penalties for non-compliance include fines and mandatory allowance purchases. European and UK systems will operate in parallel, creating dual reporting requirements for cross border traders. Default emissions values will apply where actual supplier data is unavailable, typically resulting in higher costs.

Managing carbon costs in procurement and tenders

Procurement strategies will need to account for carbon pricing as a permanent cost factor. Buyers should begin requesting emissions data from suppliers now, before it becomes a compliance requirement. This is particularly important for imported goods, where foreign suppliers may not currently track carbon footprints. Early engagement gives suppliers time to implement monitoring systems and provide accurate data, which can reduce costs compared to using default values.

Tender processes for public sector contracts already incorporate carbon considerations through policies like Procurement Policy Note 06/21. This government guidance requires suppliers to publish carbon reduction plans and report emissions. As carbon pricing expands, private sector buyers are likely to adopt similar approaches. Suppliers that can demonstrate lower emissions will have a competitive advantage, because their products will carry lower carbon costs. This creates an incentive to invest in efficiency improvements and low carbon processes.

Long term supply agreements present both risks and opportunities. Fixed price contracts signed before 2027 may not account for carbon border adjustment costs, leaving buyers or suppliers exposed to unexpected expenses. Contracts should include clauses that address how carbon costs will be allocated if regulations change. Conversely, buyers who lock in supply from low carbon sources now may benefit from cost stability as carbon prices rise.

We work with SMEs to integrate carbon considerations into procurement decisions and supply chain management. Our sustainable procurement support helps businesses assess supplier emissions, request appropriate data, and build carbon costs into sourcing strategies. For public sector suppliers, we provide guidance on meeting PPN 06/21 requirements and preparing carbon reduction plans that satisfy tender criteria. These steps are not just about compliance. They are about protecting margins and securing competitive positions in a market where carbon costs are becoming embedded in every transaction.

Businesses should also consider how carbon pricing affects product design and material choices. Substituting high carbon materials with lower carbon alternatives can reduce exposure to both the emissions trading scheme and border adjustment charges. For example, specifying recycled steel instead of virgin steel reduces embedded emissions and therefore carbon costs. Similarly, sourcing cement with supplementary cementitious materials lowers the carbon content compared to traditional Portland cement. These decisions require collaboration between procurement, technical teams, and suppliers, but the cost savings can be significant.

Where to find official guidance and updates

The Department for Energy Security and Net Zero publishes detailed information on the UK Emissions Trading Scheme, including current allowance prices, compliance deadlines, and regulatory updates. Their guidance documents explain how the scheme operates and what obligations apply to covered installations. Businesses can access this information at the UK Emissions Trading Scheme collection on GOV.UK.

Information on the Carbon Border Adjustment Mechanism is still emerging as the government drafts detailed regulations. HM Revenue and Customs will administer the border adjustment system, so their guidance will be critical for importers. Businesses should monitor HMRC announcements for updates on implementation timelines and reporting requirements. In addition, the Department for Energy Security and Net Zero provides policy updates and consultation opportunities.

For businesses that need to understand how European rules will interact with UK regulations, the European Commission publishes comprehensive materials on the EU Carbon Border Adjustment Mechanism. This is particularly relevant for UK exporters who sell into EU markets. The EU CBAM information page provides technical guidance and implementation updates.

Our compliance services support businesses in navigating carbon reporting requirements and preparing for regulatory changes. We help SMEs understand what data they need to collect, how to verify emissions with suppliers, and how to integrate carbon considerations into business planning. We also provide training through SBS Academy on carbon accounting, Scope 3 emissions, and supply chain carbon management. These resources are designed to give businesses practical skills they can apply immediately, rather than abstract policy knowledge.
