SUSTAINABILITY / SECTOR LENSES
Energy & Utilities
Grid decarbonisation, renewable energy procurement, ESOS compliance, and the energy transition. A sector undergoing structural transformation at scale.
In brief
The energy sector sits at the centre of the decarbonisation transition. For energy producers and utilities, the framework is primarily regulatory and market-driven: CfD auctions for new renewable capacity, Ofgem regulation for grid operations, and decarbonisation targets embedded in licence conditions. For corporate energy consumers — which includes most organisations of any scale — the obligations are ESOS audits, SECR reporting, and increasingly the voluntary commitments (RE100, EP100, EV100) that signal transition strategy to investors and customers.
Scope 2 emissions reduction through renewable energy procurement is often the fastest and lowest-cost sustainability action available to a corporate. The credibility question is additionality: a Power Purchase Agreement with a new renewable generator is fundamentally different from purchasing REGO certificates from existing generation.
The framework landscape
Mandatory energy audit every four years for UK organisations with 250+ employees, or turnover above €50M and balance sheet above €43M. Covers buildings, transport, and industrial processes. Phase 3 compliance deadline June 2024. Action Plans now required — not just audits.
Annual mandatory energy and carbon reporting in the directors' report for large UK companies. Covers Scope 1, Scope 2, and at least one Scope 3 category. Includes an intensity metric. Applies to companies meeting two of three criteria: 250+ employees, £36M+ turnover, £18M+ balance sheet.
Corporate commitment to source 100% of electricity from renewables. Over 400 member companies. The dominant voluntary energy commitment globally. Signatory to major institutional procurement frameworks. Key question: additionality — PPA-backed renewables are significantly more credible than REGO certificates alone.
Commitment to double energy productivity within 25 years — getting twice as much economic output per unit of energy. Complements RE100 by focusing on demand reduction rather than just supply switching.
Commitment to transition fleets and enabling infrastructure to electric by 2030. Relevant for organisations with significant vehicle fleets or car parks. Connects to Scope 1 emissions reduction for transport.
UK government auction mechanism for renewable energy generators. Sets a guaranteed strike price for electricity generation. The primary route for new renewable energy investment in the UK. Relevant for energy producers, not consumers.
Two methods: location-based (grid average) and market-based (contractual instruments: PPAs, REGOs). Market-based method allows renewable energy procurement to reduce reported Scope 2 emissions. RE100 requires market-based accounting.
Proposed on 2 June 2026: a 535 MtCO2e cap for 2038 to 2042, roughly an 87% cut on 1990 levels, with Parliamentary approval expected by 30 June. The long-term decarbonisation trajectory that energy producers and large consumers now plan against.
The SBTi recalibrated its near-term Absolute Contraction Approach (29 April 2026): near-term reduction rates are now base-year and timeline-calibrated, effectively halving the near-term bar for new target-setters. A genuine reduction in the barrier to setting a credible science-based target.
Climate disclosure is arriving at different speeds across jurisdictions. California's CARB SB 253/261 sets a Scope 1 and 2 reporting deadline of 10 August 2026, and Japan's FSA is mandating ISSB-aligned reporting from financial year-ends in March 2027. Energy groups operating across borders must report regardless of which way any single government moves.
Where organisations typically start
Corporate energy consumers
ESOS compliance is the immediate mandatory obligation for qualifying organisations. SECR reporting follows for large companies. From there: a Scope 2 reduction strategy through renewable energy procurement (PPA or REGO, with additionality considerations) typically delivers the fastest measurable carbon reduction. RE100 signals commitment to the market.
Energy producers & developers
CfD auction strategy determines investment planning. Grid connection capacity and timing is the primary operational constraint. Community benefit requirements and local planning engagement are increasingly significant for large-scale projects.
