Our Eco-Skies CarbonChoice program provides customers with the opportunity to reduce the carbon footprint associated with their air travel through the purchase of carbon offsets. Our corporate customers can take advantage of a similar program, with the option to purchase carbon offsets for both cargo shipments and business travel. Available through our partnership with Conservation International, the carbon offsets allow participants to support projects designed to help reduce greenhouse gases and provide social and economic benefits to communities around the world. Learn more about calculating your carbon offsets.

How the program works

After you calculate the carbon footprint of your travel using our carbon calculator, you will have the option to donate to one of Conservation International’s carbon reduction projects. Conservation International will invest your contribution in the selected project through the purchase of carbon offsets, which represent a certain amount of reduction in greenhouse gases.

CarbonChoice for businesses and cargo

CarbonChoice gives our corporate customers the ability to track and offset the emissions associated with their business travel and freight shipments on United.

Community-based forest conservation in Peru:

Your support for Conservation International's Alto Mayo Forest Carbon Project in northern Peru helps to protect a critical watershed for more than 240,000 people and many threatened species found nowhere else on Earth. The project also provides jobs for local families and incentivizes new approaches to farming that support rather than undermine native forests. This project is an independently verified REDD+ carbon offset project registered under the Verified Carbon Standard (VCS).

Carbon offset program FAQs

  • Carbon offsetting is a process designed to alleviate the impact of greenhouse gas emissions that result from the use of fossil fuels by reducing emissions from another source. Through this process, United customers now have the opportunity to offset the carbon emissions resulting from their travel by making tax-deductible charitable contributions to a variety of independently reviewed and certified environmental projects focused on forest conservation, renewable energy and avoided deforestation.

    After you book your flight, you will be given the option to calculate your emissions and offset your carbon, or you can simply visit our carbon offset website and enter either your itinerary information or a dollar amount that you’d like to contribute.

  • The calculations we use are based on actual fuel consumption of the United Airlines fleet. Calculations are based on a comprehensive carbon footprint of our flight operations, specific to routes, planes utilized, load factors, assumed passenger weight and actual fuel use. The carbon calculator only assigns the emissions associated with individual passenger travel and does not include other emissions generated by cargo transport, crew travel, etc.

    Calculations represent the CO2 emitted during fuel combustion and do not account for upstream CO2 emissions from fuel production, refinement and transportation by oil companies. While upstream emissions are difficult to measure precisely, some estimates suggest that they account for approximately 16% of a fuel’s total life cycle CO2 emissions.

  • A tonne (t) or metric ton (M/T), also referred to as a metric tonne, is a measurement of mass equal to 1,000 kilograms. 1 tonne = 1.102 U.S. tons, or 2,204 pounds.

  • We've worked with Conservation International since 1998 as part of its Business & Sustainability Council, a community of companies committed to leveraging their business experiences and resources to protect nature for the benefit of humanity. In more than 30 countries, CI addresses the root causes of climate change by protecting carbon-rich ecosystems; harnessing nature-based solutions to buffer climate change impacts; advising on policies to support climate resilience; and developing financial instruments to magnify our efforts.
