After that interaction, he was inspired to start Travalyst (“travel” and “catalyst”), a nonprofit that provides people booking travel with emissions and other sustainability data so they can consider the lowest impact options. The aim is to help make a dent in the industry’s carbon footprint; tourism makes up about [11%](https://www.bloomberg.com/news/articles/2022-11-14/how-tourism-can-hit-net-zero-by-2050-an-unrealistic-but-not-impossible-solution "undefined") of global greenhouse gas emissions. Travalyst worked with Google to create the Travel Impact Model, a free, publicly available methodology [launched in 2022](https://travalyst.org/news/travalyst-launches-standardised-way-to-calculate-carbon-emissions-for-air-travel/ "undefined") that predicts per-passenger CO2 emissions produced by upcoming flights. Travalyst’s coalition of partners, representing a combined market value of $3 trillion, includes top tech companies used by tourists like Booking.com, Expedia Group, Mastercard, Skyscanner, Tripadvisor and Visa. On Sept. 12, Travalyst announced that its flight emissions data has appeared in [65 billion searches](https://travalyst.org/news/flight-emissions-data-shown-in-over-65-billion-searches-worldwide/ "undefined") worldwide. Prince Harry has stressed that sustainable travel also means travel that boosts local economies and supports tourism businesses that hire local talent. He summed up Travalyst’s mission at its fifth anniversary celebration on Sept. 24 during Climate Week: “As I sought solutions to some of the world's most pressing conservation challenges, I quickly realized just how profound an impact the travel and tourism industry has…together we are proving that travel can be a force for good. So let’s continue this journey together and make sure that travel benefits everyone everywhere.” ```json [{"@context":"https://schema.org","@type":"Article","@id":"https://time.com/collections/time100-climate-2024/7172552/prince-harry-climate/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/collections/time100-climate-2024/7172552/prince-harry-climate/"},"headline":"TIME100 Climate 2024: Prince Harry, Duke of Sussex","datePublished":"2024-11-12T11:23:03.000Z","dateModified":"2026-03-03T00:41:52.229Z","description":"Find out why Prince Harry, Duke of Sussex was selected for the list.","url":"https://time.com/collections/time100-climate-2024/7172552/prince-harry-climate/","keywords":["climate","list","TIME100 Climate"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt11831e80c5f3fdbc/698a9c179862f5812489cb25/Titans_Prince_Harry_Duke_of_Sussex.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Olivia B.
