Beginning today, Hopper will be the first travel-booking app to offer free carbon dioxide (CO₂) emissions offsets on behalf of our customers for every flight and hotel purchased in the app. Guided by the EPA’s Center for Corporate Climate Leadership Emission Factors report, for every booking made on Hopper, the travel-booking app will donate the funds to plant four trees per flight sold and two trees per hotel room sold in partnership with Eden Reforestation Projects. An SGS Forest Management certified 501c3 non-profit, Eden has planted over 265 million trees across formerly deforested areas in Madagascar, Indonesia, Kenya, and Mozambique since its inception in 2005. Recent research led by the lab of Professor Tom Crowther at the Swiss university ETH Zürich has quantified the impact that global forest restoration can have on the environment, finding that it is “one of the most effective carbon drawdown solutions to date,” with “the potential to store an equivalent of 25% of the current atmospheric carbon pool." With the implementation of Hopper Trees, we expect to see at least six million trees planted in 2020 in an effort to offset CO₂ emissions from the flights and hotels booked on Hopper this year. We are excited to take this step toward a more sustainable future, and we are pleased to see that we are aligned with our customers in viewing this commitment as a priority as well.
