UK Carbon Border Adjustment Mechanism: What It Means for Your Business

In 2023, the UK Government announced plans to introduce a carbon border tax from 2027, known as the UK Carbon Border Adjustment Mechanism (UK CBAM). This policy aims to prevent carbon leakage (the practice of shifting emissions-intensive production to countries with weaker climate policies) by ensuring that imported goods are subject to a comparable carbon price as those produced domestically under the UK Emissions Trading Scheme (UK ETS). Ultimately, the goal is to drive global reductions in industrial emissions and support the transition to a low-carbon economy.


What is the UK CBAM?


The UK CBAM will apply to imported goods in emissions-intensive industries. Starting in 2027, businesses importing iron, steel, aluminium, ceramics, cement, fertilisers, glass and hydrogen into the UK will be required to:


  • Mandatory Disclosures: Submit reports detailing the carbon emissions embedded in their products (embodied carbon). The UK CBAM will require reporting to detail the Scope 1 (direct emissions from production), Scope 2 (indirect emissions from purchased electricity), and select precursor product emissions embodied in imported products.


  • Levy Payments: Pay a levy based on the carbon pricing of the exporting country.


If the exporting country has little to no carbon pricing, UK importers will be subject to a higher tax rate. This initiative encourages businesses to source materials from suppliers with strong carbon policies, incentivising sustainable production methods.


How Will it Work?


The UK CBAM will require importers to report and pay for the emissions embedded in their products at the UK ETS carbon price. If a foreign producer has already paid a carbon price in the country of manufacture, this may be deducted from the payment charge under UK CBAM to avoid double taxation.


The UK Government has proposed to have four accounting periods per year to align with the standard practices used by other taxes.


How Does the UK CBAM Differ from the EU CBAM?


While both mechanisms share the same overarching objectives, there are key differences:


  • Scope of Products: The EU CBAM applies to cement, iron, steel, aluminium, fertilisers, electricity, and hydrogen, whereas the UK CBAM excludes electricity imports but also applies to additional products, such as ceramics and glass.


  • Implementation Timeline: The EU CBAM has already begun its transitional phase (October 1, 2023), requiring emissions reporting, with full financial enforcement starting in 2026. The UK CBAM, however, will take effect in 2027.


What Can Businesses Do to Prepare?


To limit exposure and ensure compliance with UK CBAM, businesses should take the following steps:


  • Assess Supply Chains: Assess your exposure to UK CBAM by reviewing your suppliers to understand where imported products and materials are being manufactured and their carbon intensity. Identify other suppliers with lower-carbon intensities.


  • Engage Key Suppliers: Work with your suppliers to encourage the adoption of low-carbon technologies and practices that will reduce the carbon intensity of manufactured materials. Consider switching suppliers and sourcing materials from UK-based companies that already comply with UK ETS, to reduce exposure.


  • Comprehensive Emissions Reporting: Ensure you have sufficient emissions accounting and reporting practices in place, to minimise disruption caused by mandatory reporting. We recommend businesses understand their Scope 1, 2 & 3 emissions to identify high-impact activities and inefficiencies within their operations and their supply-chain.

SMEs make up 99% of UK businesses, three fifths of employment, over 50% of all business revenue, are in everyone's supply chain, and are exposed to largely the same threats as large enterprises. How should they get started with cyber security? Small and Medium sized Enterprises (SME) are not immune to the threat of cyber attacks. At the very least, if your business has money then it will be attractive to criminals. And even if you don’t have anything of value, you may still get caught up in a ransomware campaign with all of your data and systems made inaccessible. Unfortunately many SMEs do not have an IT team let alone a cyber security team. It may not be obvious where to start, but inaction can have significant impact on your business by both increasing risk and reducing the confidence to address new opportunities. In this article we outline 5 key questions that can help SMEs to understand what they need to do. Even if you outsource your IT to a supplier these questions are still relevant. Some can’t be delegated, and others are topics for discussion so that you can ensure your service provider is doing the right things, as well as understanding where their responsibilities stop and yours start. Q1: What's Important & Worth Defending Not everything needs protecting equally. In your personal life you will have some possessions that are dear to you and others that you are more laissez-faire about. The same applies to your digital assets, and the start point for any security plan needs to be an audit of the things you own and their importance to your business. Those ‘things’, or assets, may be particular types of data or information. For instance, you may have sensitive intellectual property or trade secrets; you may hold information about your customers that is governed by privacy regulations; or your financial data may be of particular concern. Some of this information needs to be protected from theft, while it may be more important to prevent other types of data from being modified or deleted. It is helpful to build a list of these assets, and their characteristics like the table below:
