Reducing Your Carbon Footprint: Practical Ways to Live More Sustainably

United Airlines’ environmentally friendly efforts lessen the impact on local U.S. communities.

United Airlines is reducing its environmental footprint across airports in the United States. The carrier combines passenger comfort with a clear commitment to sustainability, aiming to cut greenhouse gas emissions by 50 percent by 2050. To reach that goal, United implements a range of initiatives at several major U.S. hubs.

Los Angeles International Airport
A signature element of United’s sustainability work at LAX is its investment in biofuels. Made from renewable materials such as agricultural residue and municipal waste, these fuels helped power the first U.S. commercial flight using renewable biofuel in 2011. Since 2016 United has also been the first airline to use biofuel regularly for scheduled flights from Los Angeles, demonstrating a long-term dedication to lower-emission operations.

San Francisco International Airport
United operates from Terminal 3 at SFO, one of the nation’s more environmentally conscious terminals. Terminal 3 holds LEED Gold certification and incorporates solar panels and terrazzo flooring produced from recycled glass. The terminal design maximizes natural light and offers open views, creating a lighter, more sustainable airport environment for travelers.

Chicago O’Hare International Airport
United’s collaboration with biofuel producer Fulcrum BioEnergy includes plans to build a Chicago-area plant. When operational, the facility is expected to produce roughly 33 million gallons annually, about half of which would be jet fuel. That production not only helps lower the airline’s carbon emissions but also diverts waste from landfills and supports local jobs, with hundreds of construction positions and long-term employment projected.

Denver International Airport
At Denver, United partnered with Certifiably Green Denver to enhance both United Club locations at DEN. Both clubs earned the Certificate of Environmental Excellence after upgrades that improved energy efficiency and expanded composting and recycling practices. Travelers continue to enjoy United Club amenities while benefiting from the facilities’ reduced environmental impact.

Houston George Bush Intercontinental Airport
United has been transitioning ground support equipment to electric power across its network. While 39 percent of the airline’s ground equipment is electric systemwide, IAH stands out with about 74 percent electrification. Increasing electric ground operations reduces emissions and fuel consumption, improving air quality for airport employees and passengers.
