Charpin: As Keesup mentioned, it’s complex because it’s fragmented, but also, and very importantly, it’s not yet standardized. However, there’s been significant progress with groups emerging to help establish sustainability standards for the travel industry. For instance, Mastercard recently joined the Travalyst Coalition, which aims to bring consistent sustainability information to the mainstream to help business and leisure travelers make more conscious travel choices. Travalyst has so far focused on scaling sustainability data for aviation and accommodation such as the Travel Impact Model, which since its launch has shown flight emissions estimates to over 65 billion travelers at the point of booking.
While significant progress has been achieved with standardizing flight emission data, the hotel industry is considerably more difficult. There’s not yet a clear consensus that this given hotel has the equivalent of this specific carbon footprint. Rather, an online travel booking platform can use one measurement and a major hotel chain can use another. The push for standardization throughout the entire travel industry is more important than ever.
