Manufacturing's Unique Position
UK manufacturers face multiple overlapping reporting requirements while managing complex supply chains. The sector's energy intensity makes it a priority for both compliance and cost reduction initiatives.
Key Reporting Requirements for Manufacturing
UK ETS
Emissions Trading System for high-energy manufacturers
- • Annual verified emissions
- • Allowance trading
- • Free allocation rules
- • Benchmarking data
Applies: Energy use >20 GWh/year
ESOS Phase 3
Energy efficiency compliance scheme
- • Energy audits
- • Efficiency recommendations
- • Senior responsible person
- • Board oversight
Deadline: 5 December 2026
SECR
Streamlined Energy & Carbon Reporting
- • Energy consumption
- • GHG emissions (Scope 1&2)
- • Energy efficiency actions
- • Intensity metrics
Threshold: £36m+ turnover
UK SRS
UK Sustainability Reporting Standards
- • Climate disclosures (S2)
- • Scope 3 supply chain
- • Transition planning
- • Physical climate risks
Expected: Large manufacturers 2027+
UK ETS Participation and Disclosure
Covered Installations
Manufacturing facilities using >20 GWh annually or producing specified volumes of:
- • Steel: >2.5 tonnes/hour crude steel capacity
- • Aluminium: >20 tonnes/day
- • Cement: >500 tonnes/day clinker
- • Lime: >50 tonnes/day
- • Glass: >20 tonnes/day melting capacity
- • Ceramics: >75 tonnes/day production capacity
- • Chemicals: Various thresholds by product
Reporting Obligations
Annual Emissions Report
Due 31 March, third-party verified
Allowance Surrender
Due 30 April following reporting year
Monitoring Plan
Detailed methodology for emissions calculation
Improvement Reports
Energy efficiency and process improvements
Disclosure Impact: UK ETS participation and carbon pricing should be disclosed in climate risk assessments under TCFD and UK SRS frameworks.
Manufacturing Supply Chain Emissions
For manufacturers, Scope 3 typically represents 80-90% of total emissions, dominated by purchased goods, services, and end-of-life treatment.
Upstream (Categories 1-8)
Raw materials, components, packaging
Machinery, equipment, buildings
Inbound logistics
Downstream (Categories 9-15)
Product energy consumption in use
Product disposal and recycling
Outbound logistics
Supplier Engagement Strategy
Tier 1 - Strategic Suppliers
Direct data collection, emissions targets, joint improvement projects
Tier 2 - Key Suppliers
Supplier questionnaires, CDP Supply Chain, sustainability requirements
Tier 3 - Other Suppliers
Spend-based estimates, sector averages, contractual sustainability clauses
Energy Intensity Metrics for SECR
SECR requires manufacturing companies to report an energy intensity metric that relates energy consumption to business activity.
Production Volume
kWh per tonne produced
✓ Most common for manufacturing
Revenue
kWh per £ turnover
⚠ Affected by pricing changes
Floor Area
kWh per m² facility
For multi-product facilities
Value Added
kWh per £ gross value added
For high-value products
Best Practice: Multiple Metrics
Leading manufacturers report 2-3 intensity metrics to provide comprehensive view:
- • Primary metric: Energy per tonne of main product (production-based)
- • Secondary metric: Energy per £ revenue (business performance)
- • Facility metric: Energy per m² for multi-site operations
ESOS Phase 3 Documentation
Critical Deadline: 5 December 2026
ESOS Phase 3 compliance deadline. Unlike previous phases, this includes mandatory energy efficiency recommendations and board-level oversight requirements.
Energy Audits
- 90% of energy use covered
- ISO 50001 route available
- Lead assessor certification
- Cost-effective recommendations
Board Governance
- Senior responsible person
- Board sign-off evidence
- Implementation monitoring
- Annual progress reviews
Documentation
- ESOS notification to EA
- Audit evidence package
- Total energy calculation
- Compliance statement
ISO 50001 Alternative Route
Manufacturing companies with ISO 50001 energy management certification can use this as evidence of ESOS compliance, reducing audit burden while demonstrating continuous improvement in energy performance.
