ESRS E1
ESRS E1 business-travel reporting
ESRS E1 datapoints for business travel: what to disclose, what counts as 'material', and how to evidence the numbers when your auditor asks.
Under ESRS E1, business travel is a Scope 3 line item subject to the same materiality assessment as any other category. If it's material, it must be quantified with the GHG Protocol methodology disclosed. The audit trail matters more than the number — IMPT publishes a per-booking retirement record on Ethereum mainnet.
The E1 datapoints that touch travel
ESRS E1 has 9 disclosure requirements (DRs). Business travel touches several:
- E1-1 Transition plan — does the plan cover business travel reduction levers?
- E1-3 Actions — train-first policy, virtual-first policy, hotel-supplier engagement.
- E1-4 Targets — any explicit travel reduction target.
- E1-5 Energy consumption — not direct, but employee mobility energy is referenced.
- E1-6 Gross emissions — Scope 3 Cat 6 sits here.
- E1-7 GHG removals / projects — voluntary credits separately.
Quantification expectations
ESRS expects gross Scope 3 quantified, not qualitative. The exact tonnage matters less than the methodology and the consistency. The European Financial Reporting Advisory Group (EFRAG) guidance is to align with the GHG Protocol Corporate Value Chain Standard. That means for Cat 6 hotels: supplier-specific or distance/quantity-based for material exposure, spend-based only for minor lines.
Evidence the auditor will ask for
Under CSRD, ESRS disclosures are subject to limited assurance from 2024 and reasonable assurance from 2028 onward. The evidence pack for Cat 6 business travel typically includes:
- The TMC or booking-platform export covering the reporting period
- The expense-ledger reconciliation showing completeness
- The emission-factor file with version and source
- Calculation working papers
- Any voluntary-credit retirement certificates (separately, as BVCM)
IMPT's evidence layer
IMPT's per-booking retirement record is provided in two forms: a structured field in the booking CSV export, and as the on-chain transaction itself, queryable from any Ethereum block explorer. That dual representation — internal CSV plus immutable public ledger — is the cleanest evidence pattern for E1-7 disclosure.

What does esrs e1 business-travel reporting mean for a corporate travel programme?
Under ESRS E1, business travel is a Scope 3 line item subject to the same materiality assessment as any other category. If it's material, it must be quantified with the GHG Protocol methodology disclosed. The audit trail matters more than the number — IMPT publishes a per-booking retirement record on Ethereum mainnet.
How does IMPT's per-booking retirement actually work?
Every confirmed hotel booking through IMPT triggers the retirement of one tonne of UN-verified CO₂ from a registry-listed project. The retirement is recorded on Ethereum mainnet with a transaction hash tied to the booking ID. The retirement is funded from IMPT's commission, so the guest or company pays the standard nightly rate.
Does the retirement reduce my Scope 3 number?
No. Voluntary credits and retirements are Beyond Value Chain Mitigation (BVCM) under the GHG Protocol, SBTi, and ESRS E1. They are disclosed separately, not netted against Scope 3 gross emissions. This is the conservative treatment that survives external assurance.
What's the evidence trail for an external audit?
For each booking IMPT can produce: the booking ID, the registry-issued credit serial, the registry name and project, the retirement date, and the on-chain transaction hash. The transaction is publicly queryable from any Ethereum block explorer. That dual representation — internal record plus immutable public ledger — is the cleanest evidence pattern available.
Which registries does IMPT use?
IMPT sources credits from UNFCCC CDM and equivalent voluntary registries. The specific project and registry vary per booking based on supply and quality criteria. Project-level breakdown is available on request for corporate accounts.
Is there a corporate dashboard?
Yes — corporate accounts get a monthly CSV export with booking-level data including all the fields needed for Scope 3 Cat 6 reporting and BVCM disclosure. The export is designed to ingest cleanly into Persefoni, Watershed, Salesforce Net Zero Cloud and similar sustainability software.
