A Sector Under Mounting Pressure
Tourism's environmental footprint is concentrated unevenly across its value chain. Aviation accounts for roughly 40% of the sector's carbon footprint, while accommodation contributes about 21%, with hotels alone responsible for 1% of global CO2 emissions, and ground transport and on-site activities make up the remainder. To stay aligned with Paris Agreement pathways, tourism emissions need to decline by more than 10% annually, a rate current growth trends make increasingly difficult to reach, and hotels specifically are being asked to cut carbon intensity per room by 66% by 2030 and 90% by 2050.
Regulation has hardened around these numbers. Since 2022, ESG reporting has shifted from a voluntary exercise to a legally enforceable obligation in major markets, with the EU CSRD requiring double materiality assessments and value chain disclosure, and the ReFuelEU Aviation regulation mandating a rise in sustainable aviation fuel blending from 2% in 2025 to 70% by 2050. Capital markets have followed this shift: hotels with strong ESG standards attract 3-9% price premiums, and major operators including Accor and IHG have issued sustainability bonds to fund low-carbon retrofits.
Yet sustainable aviation fuel represented only 0.53% of global jet fuel in 2024, despite production doubling year on year, illustrating how far implementation still lags ambition even where capital and regulation are aligned.

Three Forms of the Sustainability Gap
The say-do gap in consumer demand
Consumer demand data reveals the clearest version of the sustainability gap. 92% of travelers say they are willing to consider sustainable travel options, yet only 56.9% have actually chosen one, and just 21% say they would pay up to 5% more for a sustainable trip. This is not simple hypocrisy. Confusion about what qualifies as genuinely sustainable, skepticism about greenwashing, and price sensitivity all suppress conversion from stated intent to booking behavior. For operators, this means marketing sustainability credentials alone will not shift revenue. Pricing and product design have to make the sustainable choice the easier, clearer, and more competitively priced one, rather than leaving conversion to a traveler's willingness to research and pay more.
An assurance gap undermines credibility
Disclosure quality has not kept pace with disclosure volume. While adoption of frameworks like GRI, TCFD, and CDP has accelerated across the sector, only 18% of hospitality companies have validated science-based targets, and just 52% of top hospitality firms carry any independent assurance on their sustainability data, most of it at the limited rather than reasonable level. As CSRD and ISSB standards push the sector toward reasonable assurance, unaudited claims become a regulatory and reputational liability rather than a marketing asset, particularly as the EU Green Claims Directive and similar rules begin targeting misleading sustainability claims directly.
The franchise model limits operational control
Ownership structure compounds the gap. IHG's portfolio expansion produced a 7.2% increase in total carbon emissions since 2019 despite per-room intensity improvements, a direct consequence of an asset-light, franchise-heavy growth model in which brand-level targets do not translate automatically into franchisee-level action. Voluntary incentive programs can nudge owner behavior, but they cannot substitute for operational control. This matters because franchise and management-agreement models dominate global hotel growth, meaning decarbonisation commitments made at headquarters routinely outpace what happens on the ground.

What Leaders Should Do Now?
Move from disclosure to assurance
Leaders should treat independent, reasonable-level assurance on ESG data as a near-term requirement rather than a future compliance milestone, since regulatory timelines under CSRD and ISSB are compressing the runway to get there.
Redesign the sustainable choice, not just the message
Closing the say-do gap requires pricing, product bundling, and default options that make the sustainable choice the path of least resistance for guests and corporate travel buyers, rather than an opt-in premium dependent on a traveler's willingness to research and pay more.
Build franchisee and supplier accountability into governance
For asset-light and franchise-driven groups, emissions targets set at the corporate level need matching mechanisms, such as green finance terms and franchise agreement clauses, that extend accountability to independent owners and suppliers rather than stopping at brand-level reporting.

Conclusion
The gap between what hospitality and tourism companies claim and what they can verify is no longer just a reputational concern. It is increasingly a financial one, shaping access to capital, insurance costs, and regulatory exposure.
The operators that close this gap first, through assured data, structural accountability, and products that make sustainability the default rather than the exception, will be the ones setting the terms of competition in the decade ahead.

Frequently Asked Questions
What is the sustainability gap in hospitality and tourism?
It is the widening distance between hospitality and tourism companies' sustainability commitments and their verified operational and financial performance against those commitments.
Why do most travelers not choose sustainable travel options despite saying they want to?
Confusion about what qualifies as sustainable, skepticism about greenwashing, and price sensitivity keep actual bookings well below stated intent, with only 56.9% of travelers having chosen a sustainable option despite 92% expressing interest.
How much of tourism's carbon footprint comes from aviation versus hotels?
Aviation accounts for roughly 40% of tourism's carbon footprint, compared with about 21% from accommodation, and hotels alone are responsible for 1% of global CO2 emissions.
Does ESG performance actually affect hotel financial results?
Yes, hotels with strong ESG standards command 3-9% pricing premiums and superior occupancy compared with non-certified properties.
Why is the franchise hotel model a challenge for decarbonisation?
Franchise and asset-light structures separate brand-level sustainability targets from operational control, since independent owners, not headquarters, manage day-to-day energy, waste, and emissions decisions.
