ESRS E1: climate change

Climate is the topic every CSRD report covers in most depth, and ESRS E1 is where the numbers investors, banks and customers look for sit: emissions, targets, energy use and the transition plan. The 2026 revision trimmed and reorganised it rather than changing its purpose. This guide explains what ESRS E1 requires, what the revision changed, works through a manufacturer's key disclosures, and covers the link to IFRS S2 and the timing.

Short answer

ESRS E1 is the climate change standard of the European Sustainability Reporting Standards, which companies in scope of the CSRD apply when climate change is material, as it is for almost every company. In the revised ESRS, adopted in 2026 and mandatory from financial year 2027, ESRS E1 has 11 disclosure requirements: the transition plan for climate change mitigation; identification of climate-related risks and scenario analysis; resilience; policies; actions and resources; targets; energy consumption and mix; gross scope 1, 2 and 3 greenhouse gas emissions; GHG removals and carbon credits; internal carbon pricing; and anticipated financial effects. The revision keeps scope 3 and both scope 2 methods mandatory, lets companies choose any of the GHG Protocol's consolidation approaches, removes the energy intensity and GHG intensity per net revenue metrics, and requires scenario analysis only where a company has carried it out. In this guide's example, a manufacturer reports a 20% cut in scope 1 and 2 emissions against a 2030 target of 42%.

Key facts at a glance, as set out in this guide.

What does ESRS E1 require?

ESRS E1 covers climate change mitigation, adaptation and energy. Its disclosure requirements in the revised standard are:

RequirementWhat it covers
E1-1 Transition plan for climate change mitigationWhether the company has a plan, its compatibility with limiting warming to 1.5 degrees, decarbonisation levers, investment and locked-in emissions
E1-2 Climate-related risks and scenario analysisHow physical and transition risks are identified, and scenarios used where the company has run them
E1-3 ResilienceHow resilient the strategy and business model are to climate change
E1-4 PoliciesPolicies on mitigation, adaptation and energy
E1-5 Actions and resourcesKey actions by decarbonisation lever and the money and people behind them
E1-6 TargetsEmission reduction targets, gross and absolute, with base years; see net zero targets
E1-7 Energy consumption and mixEnergy used, split between fossil, nuclear and renewable sources
E1-8 Gross scopes 1, 2 and 3 GHG emissionsScope 1, scope 2 location-based and market-based, and significant scope 3 categories
E1-9 GHG removals and carbon creditsRemovals in the company's operations and value chain, and credits bought or cancelled
E1-10 Internal carbon pricingCarbon prices used in decisions, and what they cover
E1-11 Anticipated financial effectsAssets and revenue exposed to physical and transition risks, and climate opportunities

A company that concludes climate change is not material must explain that conclusion in detail. See double materiality explained.

What did the 2026 revision change in ESRS E1?

  • Scenarios: scenario analysis is reported only where the company has carried it out, but the resilience assessment remains.
  • Transition plan: a plan not compatible with 1.5 degrees can be reported if the company says so transparently, and financial resources can be given as ranges.
  • Targets: prescribed target years and five-yearly updates were dropped, but targets must still be gross and absolute, set before removals, carbon credits or avoided emissions, and consistent with the inventory.
  • Emissions boundary: companies can use the GHG Protocol's financial control, operational control or equity share approach (see organisational boundaries), instead of the original standard's combined approach.
  • Fewer metrics: energy intensity and GHG intensity per net revenue were removed, and anticipated financial effects can be given as ranges, with phase-ins.

Scope 3 remains mandatory where climate is material. See the revised ESRS.

ESRS E1 in practice: a manufacturer's key disclosures

An EU manufacturer in scope from 2027 drafts its E1 disclosures. Its base year is 2023, with scope 1 and market-based scope 2 emissions of 12,000 tonnes, and its target is a 42% cut by 2030, gross, without counting carbon credits.

Scope 1 and 2 emissions against the 2030 target (tonnes CO2e)Scope 1 and 2 emissions against the 2030 target (tonnes CO2e)12,0002023 base year9,6002026 actual6,9602030 targetReported emissionsTarget
Targets under ESRS E1 are gross, before carbon credits.

In 2026, scope 1 and 2 emissions are 9,600 tonnes, down 20%, on track for the 2030 target of 6,960 tonnes. It reports scope 2 on both methods, and scope 3 of 98,000 tonnes across its significant categories, led by purchased steel, estimated partly with the spend-based method, and the use of its products. Energy use is 60,000 MWh, 35% renewable. It bought carbon credits to support a forest project, which it reports under E1-9 separately from its emissions and does not count towards its target. Its transition plan names its levers, heat pumps, renewable electricity contracts and lower-carbon steel, with the capital expenditure behind each. See the 15 scope 3 categories and location-based and market-based scope 2. See climate transition plans.

What are anticipated financial effects?

E1-11 asks for the financial effects a company expects from material physical and transition risks and from climate opportunities, such as the carrying amount of assets exposed to flooding, revenue from activities facing carbon costs, and revenue from low-carbon products. The figures should be consistent with the assumptions in the financial statements, such as those used in impairment testing. See current and anticipated financial effects, connected information and climate risk in impairment testing.

How does ESRS E1 compare with IFRS S2?

The two were designed to be largely interoperable. Both require scope 1, 2 and 3 emissions under the GHG Protocol, a transition plan where one exists, climate resilience and financial effects. Differences remain: ESRS E1 requires market-based scope 2 as well as location-based, energy data and carbon credit details, and it sits within double materiality, so it also covers impacts. A company reporting under both maps the extra datapoints rather than preparing two sets of figures. See IFRS S2.

When does the revised ESRS E1 apply?

The revised standards apply to financial years beginning on or after 1 January 2027. For 2026 reports, companies can use the original ESRS, the revised standards, or the original standards with selected reliefs. Companies newly in scope after the Omnibus start with 2027, and non-EU groups follow from 2028. See the CSRD for non-EU companies.

Yes. Significant scope 3 categories must be reported where climate change is material.

Can carbon credits count towards ESRS E1 targets?

No. Targets are gross, set before removals, carbon credits or avoided emissions; credits are reported separately.
