Which Regulations Apply to Your Manufacturing Business?

1

Do you operate combustion or industrial processes above 20MW thermal input?

Yes → UK ETS applies. You must hold a GHG permit, submit annual verified emissions reports, and surrender allowances.

2

Do you employ 250+ staff or have £44m+ turnover and £38m+ balance sheet?

Yes → ESOS Phase 4 applies (qualification December 2026). SECR likely applies if UK-incorporated.

3

Do you export steel, aluminium, cement, chemicals, or fertiliser to the EU?

Yes → Your EU customers face EU CBAM obligations. They will require installation-level embedded emissions data from you.

4

Are you listed on the London Stock Exchange Main Market?

Yes → UK SRS S1 & S2 mandatory from January 2027. Scope 1-3, climate risks, transition plans.

5

Do you handle 50+ tonnes of packaging material per year?

Yes → Packaging EPR (pEPR) applies. You must report packaging data and pay disposal fees to the scheme administrator.

The Challenge

Why Manufacturers Can’t Afford to Wait

Carbon costs, supply chain disclosure pressure, and overlapping regulations are converging on UK manufacturing.

Carbon Cost Exposure

UK ETS allowance prices are rising as the cap tightens through 2040. Every tonne of unabated Scope 1 emissions is a direct cost — and the trajectory is legislated upward. Manufacturers with energy-intensive processes face material margin erosion.

Scope 3 Supply Chain Data

OEM and retail customers increasingly demand Scope 3 emissions data as part of procurement. Without credible, product-level carbon data, manufacturers risk losing contracts to competitors who can provide it.

Regulatory Overlap

UK ETS, SECR, ESOS, UK SRS, and pEPR create overlapping reporting demands. Without an integrated data architecture, compliance teams waste resources producing similar data in different formats for different regulators.

CBAM Downstream Risk

If you export CBAM-covered goods to the EU, your customers must report your embedded emissions. Inability to provide installation-level data means they pay default rates — and may switch suppliers.

Manufacturing ESG: Frequently Asked Questions

Which UK ETS sectors cover manufacturing?+
UK ETS covers manufacturing installations carrying out regulated activities above specified thresholds, including combustion above 20MW thermal input, metals processing (iron, steel, aluminium), mineral processing (cement, glass, ceramics), chemicals production, and paper and pulp. Operators must hold greenhouse gas emissions permits, submit verified annual emissions reports, and surrender UK ETS allowances to cover their emissions.
How does ESOS Phase 4 differ from Phase 3 for manufacturers?+
ESOS Phase 4 introduces mandatory action plans and progress reporting, moving beyond the audit-only approach of previous phases. Qualifying manufacturers must develop actionable energy efficiency plans with identified measures, estimated costs, expected savings, and implementation timelines. Progress against Phase 3 recommendations must also be reported. The qualification date is December 2026, with the compliance deadline in June 2027.
What Scope 3 categories matter most for manufacturers?+
For most manufacturers, the material Scope 3 categories are: Category 1 (purchased goods and services, including raw materials), Category 4 (upstream transport and distribution), Category 11 (use of sold products, significant for energy-consuming goods), and Category 12 (end-of-life treatment). Under UK SRS S2, Scope 3 is required on a comply-or-explain basis from January 2027 for listed companies. Supply chain pressure from large customers also drives demand.
How does EU CBAM affect UK manufacturers that export to the EU?+
EU CBAM does not directly regulate UK manufacturers, but it creates strong indirect pressure. Your EU-based customers must declare the embedded emissions in CBAM-covered goods they import. If you cannot provide actual installation-level emissions data, they must use higher default values, increasing their costs. This makes you less competitive compared to suppliers who can provide actual data. Covered products include steel, aluminium, cement, chemicals, fertilisers, electricity, and hydrogen.
Can UK ETS data be reused for SECR and UK SRS reporting?+
Yes, and this is the recommended approach. UK ETS verified emissions data for Scope 1 can feed directly into SECR disclosures and UK SRS climate metrics. However, boundary differences must be managed: UK ETS covers specific installations, while SECR and UK SRS cover the corporate entity. Energy consumed in non-ETS operations (offices, fleet, smaller sites) must be captured separately. An integrated data architecture significantly reduces compliance cost and inconsistency risk.
Does RSustain provide UK ETS verification or ESOS audits?+
No. RSustain provides advisory services only. UK ETS verification must be performed by a UKAS-accredited verification body, and ESOS audits must be led by an ESOS lead assessor. RSustain helps manufacturers prepare for both by designing monitoring plans, building evidence architectures, conducting pre-verification walk-throughs, and optimising data collection processes. This preparation typically reduces verification time and cost.
What is the UK CBAM and how does it differ from EU CBAM?+
The UK CBAM, established through the Finance Act (No. 2) 2025, applies from January 2027 to imports of CBAM-covered goods into the UK. It operates independently from the EU CBAM but covers similar product categories. UK manufacturers importing raw materials (e.g., steel for fabrication) may face UK CBAM obligations. The key difference is timing: EU CBAM definitive phase is live from January 2026, while UK CBAM starts a year later.
