ESRS E3 for Energy & Utilities Companies: 2026 Compliance Guide
- →Energy & Utilities companies in ESRS E3 scope must report on ESRS modules E1, E2, E3, E4, S1, S3, G1. Average sector readiness is only 52%.
- →Key compliance risks: Direct GHG emissions (Scope 1) and Water use (E3).
- →CBAM also applies to this sector — embedded carbon reporting required from 2026.
Which ESRS E3 requirements apply to Energy & Utilities?
Electricity generators, gas distributors, renewable energy producers and utilities.
For ESRS E3 compliance, Energy & Utilities companies must report on the following ESRS topical standards where material: E1, E2, E3, E4, S1, S3, G1. The double materiality assessment will determine which of these modules require full disclosure.
Average compliance readiness across the Energy & Utilities sector is currently 52% — significantly below the threshold needed for a clean assurance opinion. Most companies in this sector have work to do before their reporting deadline.
Key ESG risks for Energy & Utilities companies
ESRS E3 requires Energy & Utilities companies to disclose impacts, risks and opportunities across all material topics. The most commonly material topics for this sector are:
Direct GHG emissions (Scope 1)
Water use (E3)
Biodiversity impact (E4)
Just transition (S)
Energy & Utilities companies that fail their double materiality assessment risk under-reporting material topics. Auditors pay particular attention to this sector's direct ghg emissions (scope 1).
Scope 3 emissions for Energy & Utilities
Scope 3 emissions are typically the largest part of a Energy & Utilities company's carbon footprint. The most material Scope 3 categories for this sector are categories 1, 3, 4, 11 under the GHG Protocol.
For ESRS E3 compliance under ESRS E1-5, you must:
1. Screen all 15 Scope 3 categories 2. Report on material categories with documented methodology 3. Set Scope 3 reduction targets for material categories 4. Obtain third-party assurance over your Scope 3 data
ESGMaster automates Scope 3 calculation for Energy & Utilities companies using DEFRA 2026 emission factors.
Start with a spend-based Scope 3 screening across all 15 categories. This identifies which categories are material without requiring detailed activity data — you can then focus detailed calculation effort where it matters most.
ESRS E3 compliance roadmap for Energy & Utilities
Phase 1 — Assess (Months 1–3) Determine your ESRS E3 scope status, complete a double materiality assessment, and run a gap analysis against ESRS E1, E2, E3, E4, S1, S3, G1.
Phase 2 — Collect (Months 4–9) Build data collection processes for all material ESRS metrics. For Energy & Utilities, focus on direct ghg emissions (scope 1) data first — it is typically the hardest to collect and the most scrutinised by auditors.
Phase 3 — Report (Months 10–12) Draft your ESRS E3 report, engage third-party assurance, implement XBRL tagging, and file with your national authority.
ESGMaster compresses this timeline by automating Phases 1 and 2 — delivering your gap analysis in 8 seconds and your draft report in hours.

Which ESRS modules must Energy & Utilities companies report on?
Based on typical Energy & Utilities business models, the most commonly material ESRS modules are E1, E2, E3, E4, S1, S3, G1. However, you must conduct your own double materiality assessment — the final list depends on your specific operations and value chain.
What Scope 3 categories matter most for Energy & Utilities?
The most material Scope 3 categories for Energy & Utilities companies are categories 1, 3, 4, 11 under the GHG Protocol. Category 1 is typically the largest source of emissions in this sector.
How long does ESRS E3 compliance take for a Energy & Utilities company?
From zero to first ESRS E3 report typically takes 12–18 months for Energy & Utilities companies. The biggest time bottlenecks are Scope 3 data collection and third-party assurance provider engagement. ESGMaster reduces the data collection phase to weeks rather than months.
