CSRD / ESG
disclosure for shipping.

The Corporate Sustainability Reporting Directive (CSRD) and the underlying European Sustainability Reporting Standards (ESRS) — which shipping entities fall in scope, the ESRS E1 (climate) and ESRS E2 (pollution) environmental disclosure requirements the regime imposes, and the practical first steps shipowners and ESG leads should take before the next reporting cycle.

Where this fits

A reference page for shipping’s CSRD exposure — not a replacement for counsel.

CSRD / ESG sits inside Astrabe’s broader regulatory-compliance mandate, alongside the EU ETS phase-in, Med ECA, CII & EEXI, and HKC / IHM. This page is the working reference for the entity-scope test, the ESRS E1 / E2 environmental disclosure ladder, and the first steps shipowners should take under the new regime.

Entity scope

Three categories of shipping entity the CSRD captures.

CSRD does not regulate vessels directly — it regulates the corporate entity on whose books the vessels sit. The directive cascades from EU-listed parents to vessel-owning non-EU groups and to large non-listed EU companies, so the entry condition is corporate structure and footprint, not flag or tonnage. The three categories below cover practically every commercial shipping entity the regime reaches.

Category 01

EU-listed EU companies with vessels on the books.

Any undertaking whose securities are admitted to trading on an EU-regulated market and which has one or more EU/EEA subsidiaries or branches — the parent is in scope from the first reporting year following admission, irrespective of how many vessels the corporate group ultimately owns. The directive travels through the corporate chain to consolidated subsidiaries that own or charter vessels.

Category 02

EU-listed non-EU groups with significant EU activity and EU-controlled vessel-owning subsidiaries.

Non-EU parent groups whose securities are listed on an EU-regulated market, where the group has significant EU activity and at least one EU/EEA subsidiary that owns, charters, or operates vessels on a regulated route. The non-EU parent reports on its EU activity at consolidated level, with vessel-owning subsidiaries in scope on the same disclosure ladder as their EU-listed peers.

Category 03

Large non-listed EU companies that own or charter vessels.

Large undertakings meeting two of the three EU size thresholds — more than 250 employees, more than €50 million turnover, more than €25 million balance-sheet total — that own or charter commercial vessels from an EU establishment. Yacht and recreational tonnage fall outside the same size test, but a large EU shipowning group whose fleet touches commercial or offshore trades comfortably exceeds the threshold.

ESRS E1 — climate

What the climate disclosure standard asks of a fleet.

ESRS E1 is the climate-change disclosure standard under CSRD. It binds the reporting entity to disclose its governance, strategy, targets, and metrics on climate transition, along with the greenhouse-gas inventory that underwrites the disclosure. For a shipping entity, those four blocks translate into a fleet-level emissions disclosure ladder (Scope 1 / 2 from fleet operations and shore power, Scope 3 from value-chain activity) and a climate-transition plan that holds up to ESRS scrutiny.

ESRS E1
Governance — climate oversight at board and management level.
Disclosure of how climate-related impacts, risks, and opportunities are overseen by the administrative, management, and supervisory bodies of the reporting entity — board-level responsibility, committee structure, management competence on climate, and reporting lines into the disclosure cycle. For a shipowner group, the governance block is read against how fleet decarbonisation decisions actually flow through the parent board and the operating subsidiaries.
ESRS E1
Strategy — climate risks, opportunities, and the transition plan.
Disclosure of climate-related risks and opportunities for the business, the resilience of strategy and the financial planning underpinning it, and — for entities subject to ESRS E1 — a climate transition plan. A shipowner’s transition plan is read against IMO mid-term measures, the EU ETS surrender obligation, fleet-renewal cadence, and the bunker procurement slate (VLSFO, bio-blends, LNG, methanol, ammonia).
ESRS E1
Targets — measured, science-based, tracked through the disclosure cycle.
Disclosure of measurable, time-bound targets on climate mitigation and adaptation, with the baseline year, scope, and methodology stated. Fleet decarbonisation targets — absolute emissions, intensity per nautical mile or per transport work, or per vessel class — fit here, provided the baseline and methodology match what the entity reports in the rest of the standard and in adjacent regulatory returns (CII, DCS, MRV).
ESRS E1
Metrics — Scope 1, Scope 2, Scope 3, and intensity per transport work.
Disclosure of GHG emissions on the Scope 1 / 2 / 3 split, energy consumption, and the intensity metric tied to transport work (per nautical mile, per deadweight-ton-mile, per TEU-mile). For shipping, Scope 1 covers vessel fleet emissions, Scope 2 shore-purchased electricity, and Scope 3 the value-chain emissions the entity is asked to disclose under ESRS E1 paragraph 65 (charterer-borne, cargo-borne, capital-good-borne, fuel-supply-borne emissions).

ESRS E2 — pollution

What the pollution disclosure standard asks of a shipping entity.

ESRS E2 covers pollution to air, pollution to water, and pollution of soil. For a shipping entity it speaks directly to the documentary chain the operator already runs: stack-and-machinery emissions, the bunker slate, ballast and bilge discharge records, hazardous-substances inventories, and the contractual machinery around them. The E2 ladder reads against the same evidence chain that feeds Med ECA, EU ETS, CII and the IHM regime — only the disclosure conduit changes.

ESRS E2
Pollution to air — SOx, NOx, PM, and the bunker-slate disclosure.
Disclosure of air pollutants — SOx, NOx, particulate matter, and the precursors already regulated by MARPOL Annex VI. For shipping, ESRS E2 reads against the same BDN / fuel-switch / scrubber evidence chain that feeds the Med ECA, the EU ETS surrender obligation, and the DCS return — and asks how that chain is surfaced in the parent-entity sustainability statement.
ESRS E2
Pollution to water — ballast, bilge, and discharge records.
Disclosure of pollutant emissions to water, including ballast-water management, bilge discharge, anti-fouling systems, and the operational discharge records the operator maintains. The E2 water block mirrors the documentary discipline charterers and port authorities already read against in the BALLAST WATER CONVENTION and the regional discharge frameworks — the CSRD disclosure simply routes that chain into the sustainability statement.
ESRS E2
Microplastics — operational losses from fleet and yard handling.
Disclosure of microplastic emissions the entity generates in its own operations — primarily from wear on anti-fouling systems, from cargo-handling losses, and from yard and recycling operations. For a shipowner, this is the disclosure of where the entity’s operations generate microplastic emissions along the asset life — newbuild, operation, recycling — and how the disclosure routes into the parent-level sustainability statement.
ESRS E2
Particularly hazardous substances — the HKC / IHM cross-reference.
Disclosure of substances of concern and particularly hazardous substances the entity uses or generates in its operations — directly cross-references the IHM regime under the Hong Kong Convention. The E2 hazardous-substances block reads against the IHM the operator already maintains, and asks for it to be surfaced in the parent sustainability statement with metrics on where these substances are present, where they move, and where they end up across the asset life.

First steps

Five steps a shipowner should take before the first reporting cycle.

The directive is procedural as much as substantive: a first reporting cycle that opens late tends to surface gaps in the data chain rather than gaps in the rule itself. The five steps below reflect the typical sequence of work that goes into a CSRD-ready disclosure for a shipping entity — from the data inventory that feeds the standard, through materiality scoping, monitoring plan alignment, value-chain disclosure, and the disclosure controls that hold the statement up to ESRS audit.

Step 01

Build the ESRS-aligned data inventory.

Start with the data the standard asks the entity to disclose — Scope 1 / 2 / 3 emissions, energy consumption, pollutant emissions to air and water, microplastics, hazardous substances, and the intensity metrics by transport work. The inventory is mapped against what the entity already reports under EU ETS MRV, the DCS return, CII, and the IHM, so the CSRD disclosure reads off an existing evidence chain rather than a parallel one.

Step 02

Run the double-materiality assessment.

Run the double materiality test — impact materiality (how the entity’s operations affect climate and pollution) and financial materiality (how climate and pollution affect the entity’s cash flows and asset values). For a shipping entity, the assessment reads against fleet-renewal cadence, EU ETS exposure, the bunker procurement slate, IMO mid-term measures, and the disclosure ladder the EU-regulated parent already runs in adjacent returns.

Step 03

Reconcile the monitoring plan with the disclosure.

Reconcile the existing Monitoring Plan under EU ETS with the ESRS E1 disclosure the parent sustainability statement will publish. The Monitoring Plan and DCS return already capture the underlying emissions data — the CSRD disclosure routes that data, plus the Scope 3 and intensity metrics the Monitoring Plan does not capture, into the sustainability statement on a single chain.

Step 04

Map the value-chain disclosure ladder.

Map the upstream and downstream value chain the ESRS E1 Scope 3 disclosure requires — charterer-borne emissions, cargo-borne emissions, capital-goods emissions, and the bunker-supply emissions feeding the fleet. The mapping should be consistent with how the entity reports to charterers under CII clauses, how bunker purchasing teams price the BDN, and how the freight contracts surface the disclosure obligation.

Step 05

Bring disclosure controls up to ESRS audit standard.

The sustainability statement is audited at limited-assurance level from year one and moves to reasonable assurance at a later stage. The disclosure controls — segregation of duties, source-to-report traceability, evidence retention, version control on standard texts — need to be at the same level the audited annual accounts already operate. For most shipowners, the gap sits in discovery and version management rather than in raw data collection.
