American Express Global Business Travel announced it will be launching a major upgrade to its hotel emissions calculations and reporting in Q3 2025.
Clients will be able to customize their hotel emissions calculations with more precise data and broader global coverage. This transformation is a result of Amex GBT’s expanded partnership with Chooose, integrating their software beyond air travel emissions data to hotel stays.
The enhanced reporting capability helps customers analyze hotel-related emissions with more granularity and geographic specificity. Integrated directly into Amex GBT’s data platforms, the feature helps travel managers and analysts access standardized emissions data to support smarter, more informed decision-making.
Key updates include:
- More Choice: Clients will have the flexibility to choose from multiple emissions factor providers, including United Kingdom Department for Business, Energy & Industrial Strategy (UK BEIS) and Greenview data sets, both aligned with the industry-standard Hotel Carbon Measurement Initiative (HCMI) methodology, to match their internal reporting or compliance needs.
- Wider, More Precise Coverage: Greenview emissions factors cover approximately 250 countries and territories, 100+ states and provinces, and 240+ metro areas. Now, reporting can be done at the country, region, and city level, rather than using only national averages.
- Preferred Data Access: Calculations use a privatized Greenview Hotel Footprinting Tool (HFT) bulk data set, exclusively available to preferred Greenview Partners such as Chooose.
- Independent quality assurance: Methodologies used by Chooose to calculate greenhouse gas emissions from hotel stays aligns with HCMI reporting requirements according to an international accredited registrar and classification society.
John Sturino, SVP of Product and Engineering, Amex GBT, said: "This is about giving our clients better data, better tools, and better decision-making power. We’ve engineered this capability to deliver more granular emissions data, deeply integrated into our platforms, so customers can access the insights they need, right where they need them."
"With more accurate data, these improved hotel emissions reporting capabilities can help companies better assess their travel program’s environmental impact,” added Nora Lovell Marchant, VP of Global Sustainability at Amex GBT. "It’s part of our broader effort to provide the tools and insights that support more sustainable travel choices."
Emissions data stored within Amex GBT’s proprietary systems, including the Global Trip Record (GTR) and Data Lake, ensure clients receive consistent emissions data across their travel programs. It compliments other traveler-facing hotel sustainability tools at point of sale, such as eco badges and the ability to filter searches for hotels with EV charging stations, empowering travelers to make informed choices. This new tool also supports Amex GBT’s Consulting and Meetings & Events teams with enhanced reporting capabilities
