IHG Journey to Tomorrow Hotels
For corporate travel programs operating under CSRD, SECR, or voluntary GRI reporting frameworks, the IHG Hotels & Resorts portfolio offers one of the more defensible chain-wide sustainability narratives. IHG's Journey to Tomorrow 2030 strategy commits the group to science-based emissions targets, water stewardship in high-risk locations, and waste reduction across more than 6,000 properties. For travel managers, the relevant question is not the chain's headline pledge but whether individual properties carry third-party certification that will survive an audit. This guide breaks down what an IHG booking actually delivers in ESG terms — and how to document it.
What an ESG-certified hotel actually means
An ESG-certified hotel is not one that publishes a sustainability page. It is a property holding a current, third-party-audited certification against a recognised standard:
- BREEAM — building-level assessment covering energy, water, materials, land use, and management. Common across European new-builds and refurbishments.
- LEED — USGBC framework with Certified, Silver, Gold, and Platinum tiers based on prerequisites and credits across energy, water, indoor environmental quality, and site selection.
- Green Key — operational certification under the Foundation for Environmental Education, with 13 criteria areas reviewed annually and on-site audited every three years.
- EarthCheck — science-based benchmarking and certification, particularly strong in APAC, requiring year-on-year performance data on energy, water, and waste.
For sustainability reporting, only the certification number, issuing body, and validity date belong in your audit file — not the brand's marketing claims.
IHG hotels and brands that meet the bar
The IHG portfolio is uneven by design — some brands embed sustainability at the brand standard level, others rely on property-level initiative.
- Six Senses — IHG's always-on sustainability brand. Every property operates an Earth Lab, dedicates 0.5% of operating profit to a Sustainability Fund, and most carry EarthCheck or equivalent certification. Six Senses Douro Valley, Six Senses Ibiza, and Six Senses Fiji are commonly cited audit-ready properties.
- Kimpton — boutique brand with a growing LEED footprint, including Kimpton Hotel Palomar Phoenix (LEED Gold) and several LEED-certified properties in the US Pacific Northwest.
- voco — newer conversion brand with brand-standard sustainability commitments including reduced single-use plastics and linen reuse, with Green Key certifications appearing across European properties.
- InterContinental — flagship properties such as InterContinental London – The O2 hold Green Tourism Gold, and several APAC properties carry EarthCheck.
- Holiday Inn and Holiday Inn Express — variable; LEED-certified new-builds exist in North America, and Green Key adoption is accelerating across the European estate.
Always confirm certification at the property level rather than the brand level. Cross-reference with our Green Key hotels and EarthCheck hotels directories before approval.
How IMPT documents the carbon offset for audit
Certification covers the property; it does not address the residual emissions of the stay itself. IMPT closes that gap with per-booking carbon accounting:
- Per-booking offset record — every reservation generates a stay-specific emissions calculation (kg CO₂e) based on property location, room nights, and a recognised methodology aligned with the GHG Protocol Scope 3 Category 6 (Business Travel).
- Retirement serial number on request — offsets are retired from verified registries (Verra, Gold Standard), and the unique retirement serial is available for inclusion in your audit file.
- GRI 305 alignment — output formats map to GRI 305-3 (Other indirect GHG emissions) and support CSRD double-materiality disclosures.
This documentation pairs cleanly with property-level certification evidence — see our guidance on audit documentation for the full file structure your sustainability officer should maintain.
Book and document on IMPT
If your travel policy directs bookers toward IHG properties, filter to those carrying current third-party certification, then layer per-stay offsetting with retirement serials attached to the booking record. The result is an evidence trail that withstands both internal audit and external assurance.
