American Express Global Business Travel has expanded its partnership with sustainability specialist Chooose to enhance its reporting capability for hotel emissions.

The TMC announced at the Global Business Travel Association (GBTA) annual convention in Denver that its clients will have access to more precise hotel emissions data reporting provided by Chooose, starting in the third quarter of 2025.

Amex GBT VP of global sustainability Nora Lovell Marchant told BTN that this accommodation emissions data is not available at the time of booking but is accessible for post-travel reporting.

Chooose will feed Amex GBT hotel emissions data from hotel sustainability consulting consortium Greenview, explained Lovell Marchant, which includes city-level reporting across more than 240 metropolitan areas.

This data is collected from the Cornell University¡¯s Hotel Sustainability Benchmarking Index, which anonymises data sourced from thousands of hotels worldwide, based on the Hotel Carbon Measurement Initiative (HMCI), after hotels submit data to non-governmental organisations (NGOs).

Emissions are reported based on factors such as hotel location and service tier, among others, but they are not provided to the property level, added Lovell Marchant.?

Amex GBT initially partnered with Chooose to?offer airline emissions information at the point of booking.

John Sturino, SVP of product and engineering at Amex GBT, added: "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."
