UK climate policy deep dive: Industrial decarbonisation
The government is actively developing strategies and policies which will impact business and investor decisions on the future of UK industry.* Major policies include the refreshed Industrial Decarbonisation Strategy (~Q4 2025/Q1 2026), Industrial Strategy (published June 2025), Strategic Spatial Energy Plan (~2026), Regional Energy Strategic Plans (~late 2027) Circular Economy Strategy (green paper expected Autumn 2025), Carbon Border Adjustment Mechanism (CBAM) (Start of 2027) and the continued development of the UK Emissions Trading Scheme (ETS), including the possible linkage with the EU ETS. These strategies follow on from the work of successive governments to drive industrial decarbonisation, including the 2021 Industrial Decarbonisation Strategy and Emission Trading Scheme (ETS).
Industrial emissions have fallen by 63% since 1990, but the industrial sector remains the third highest-emitting sector, representing 12% of the UK’s total greenhouse gas emissions in 2023 (51.8 MtCO2e). Industrial emissions reduction has been mainly driven by a decline in UK production of some of the most emissions-intensive materials. For example between 1990 and 2023 steel production fell from 17.8 Mt to 5.6 Mt. Concurrently there has been a structural shift towards higher value and less carbon-intensive industrial activity, such as pharmaceuticals and aerospace. Between 1998 and 2022, the gross value added from UK industry grew by 26% in real terms, while the energy consumption for each unit of output by value fell by 45%.
The main decarbonisation routes for industry in terms of emissions reduction by 2040 include electrification (57%), fuel switching to hydrogen (7%) or bioenergy (5%), resource and energy efficiency (7% and 6% respectively), and carbon capture and storage (CCS) (17%).
UK heavy industry and its wider supply chain is a crucial part of the UK economy, contributing £152 billion in Gross Value Added (GVA) in 2023, and supporting over 1.4 million jobs. The sector makes up around 21% of the UK’s exports, comparable to the global average of 22%. A resilient and environmentally sustainable industrial sector was recognised as crucial for supplying the UK economy in the government’s recently published Industrial Strategy.
Demand for low carbon industrial products is growing domestically and globally. The potential value of global green trade is expected to be worth £1.8 trillion by 2030, with a potential £60-170 billion market share for the UK. The UK already has a comparative advantage in one in three green products and is the eighth largest exporter of green industrial products globally. The CCC has asserted that industrial decarbonisation presents an opportunity to boost investment in industrial manufacturing and gain a competitive advantage in low-carbon production. However, UK industry is currently facing fierce international competition, particularly on energy costs, for example industrial electricity prices were almost 50% higher than in France and Germany and four times higher than the United States and Canada in 2023. Trade friction with the EU and relative lower levels of investment have also negatively impacted the sector; analysis from 2024 found that the UK has been bottom of the G7 league for investment in 24 out of last 30 years. UK Automation and artificial intelligence are also affecting labour in industrial sectors. Government policy and business action must go hand-in-hand to futureproof UK industry and ensure it can the play a vital role in UK economic security and prosperity.
*The Climate Change Committee considers industry to including the following sub-sectors: cement and lime, iron and steel, chemicals, glass and other minerals (such as ceramics), food and drink, paper, vehicles, non-ferrous metals, non-road mobile machinery, and other industry.
Key takeaways for boards
- While some decarbonisation progress has been made, policy uncertainty and chronic underinvestment are hampering the UK’s industrial competitiveness and low-carbon transition.
- All industrial businesses must soon determine their approach to decarbonisation to stay on track with the UK’s carbon delivery plans, manage their exposure to the UK ETS, attract investment and gain a competitive advantage in low carbon production. Boards and companies need the government to provide clear guidance, adequate incentives and enabling policy to drive forward investment in industrial decarbonisation.
- The government’s existing policy pipeline creates ample opportunity to address gaps and accelerate the pace of progress.
- Clear policy on infrastructure access is essential to guide investment in dispersed industrial sites. The timeline and level of access to electricity, hydrogen and CCS networks remains unclear for many industrial sites.
- Lowering electricity costs, streamlining grid connections, and protecting against carbon leakage are key to enabling industrial electrification.
- Stronger government support for efficiency and circularity, along with demand signals like green public procurement, can enhance competitiveness and strengthen the business case for low-carbon innovation and production.
With visionary government leadership and decisive investment, the UK can create an enduring ecosystem of low carbon industry. A thriving UK industrial sector could revitalise regional economies, supply the materials needed for high-growth sectors and new infrastructure, and strengthen UK exports by leveraging a low carbon competitive edge.
Board questions
- Given the evolving industrial landscape, what are the key risks and opportunities facing our business through to 2035? How is decarbonisation considered along other factors (e.g. emerging technologies, policy, supply chain and skills) to strengthen competitiveness and resilience? What are our competitors doing/offering? What does best in class look like in our sector, in the UK&I and worldwide? What local or sectoral engagement is taking place (e.g. with other businesses in geographic proximity to sites) to explore potential opportunities for collaboration and knowledge sharing around industrial decarbonisation?
- Have we set a robust strategic ambition for decarbonisation? Are we clear what a largely zero carbon economy in 2050 means for our markets, our clients, our products and our operations? Where do we want to be in 5-10 years’ time?
- What does the energy transition mean for the risks (physical, financial, transition, systemic) our business, and our clients’ businesses, are exposed to?
- What progress has been made with developing and delivering a transition plan to decarbonise the business? What are the barriers and enablers to implementation?
- Have we assessed climate related risks, and do we understand how we are integrating adaptation and resilience into our transition plan?#
- What opportunities and risk are associated with a more circularly economy? How does circularity intersect with our climate related transition planning? Are there any opportunities for our business around industrial symbiosis (an approach where businesses collaborate to share resources, including materials, energy, water, and by-products, to reduce waste and improve resource utilisation)?
- How are factors that sit outside of the business’s direct control being considered? Such as access to infrastructure, government policy, regulation and support? What does a changing geopolitical and macroeconomic environment mean for our business?
- Are we engaging fully with our supply and value chains? Could we do more to support our supply chains in addressing their Scope 1 & 2 emissions to meet our overall decarbonisation targets?
- Are we keeping pace with current (e.g. TCFD) and evolving (e.g. ISSB) regulatory demands? Are we considering how we can leverage regulation and reporting to support our strategic ambitions and enhance our market position?
- Have we mapped our policy and transition dependencies sufficiently?
- What engagement is happening with the government to inform and understand policy development?
- What are we doing to engage with our customers, suppliers and investee companies on decarbonisation? What are our clients, customers, shareholders, investors, and employees asking us about and expecting of us on carbon and climate? Is our response sufficient?
- Is our board equipped to tackle these issues – do we have the right governance structures and competencies in place? Do we have a plan for building board competency where needed?
