Airport trips account for a significant portion of rides and are, on average, 2.5 times longer than non-airport trips. Since 2022, Uber has grown zero-emission vehicle trips on its platform to account for over 10% of all pickups and drop-offs at the 50 largest airports in the U.S. and Canada, resulting in approximately 122 thousand tons of CO2 emissions avoided. Comfort Electric and Uber Green, its low and zero-emission products, are now available at over 75 airports in the region. In 2023, the company launched its “Green Curb” program, partnering with airports to accelerate vehicle electrification by enhancing driver charging access, elevating–and promoting–the experience for green product users by lowering prices for riders. Uber has also invested in technology features like Rematch dispatching, which reduces miles driven per airport trip, and has implemented queueing solutions for drivers charging at airports.

Hertz became the first car rental company in the U.S. to commit to setting science-based targets following the Science Based Targets initiative Corporate Net Zero Standard in November 2021. In October 2021, Hertz and Uber announced the largest expansion of EVs on a mobility platform in North America and one of the largest globally. As of June 2022, 15,000 unique Uber drivers have used Tesla vehicles provided by Hertz to log more than four million electric trips and 30 million miles, an estimated 10,000 metric tons of CO2.

The Premier Restaurant Group, a MAC One company, is the operator of 16 restaurants and bars at Chicago's Midway International Airport. The company embraces all that is sustainable. In fact, all of their concessions have been reviewed and rated under the Sustainable Airport Manual rating system and were one of the first to do so.

Sweet Beginnings, LLC along with the City's Department of Family Support Services and the North Lawndale Employment Network (NLEN) made it possible for O'Hare International Airport to be the first major on-airport apiary in the U.S. The partnership with the NLEN provides valuable job experience to ex-offenders and other disadvantaged persons in the North Lawndale community- not only in beekeeping, but also in collecting and processing honey for the production of candles, soaps, and skincare products.

This airport project expands HMSHost’s food donations by getting the majority of airports onto their food donation program. A comprehensive food donation program embodies the triple bottom line. First, food waste is the largest non-recycled contributor to municipal waste streams. Food waste also accounts for large amounts of use of fresh water, fossil fuels and other resources so any reduction has a positive environmental impact. Second, there is a positive impact on the community.
