  • Each new offset project option has verified emissions reduction impacts that align with and advance United Nations Sustainable Development Goals.
  • Customers can access Delta’s upgraded carbon calculator and offset the impact of their flights through and the Fly Delta app.
  • With all air travel worldwide accounting for two percent of the planet’s greenhouse gas emissions, carbon offsets reduce CO2 in the atmosphere and add to Delta’s leading work to lessen the impact of flying on the environment.  

Customers who choose to offset their travel using the upgraded carbon calculator with Delta fund projects across the planet that use natural climate solutions and make a measurable difference in the atmosphere. These projects restore ecosystems and address deforestation, in addition to supporting local communities by offering job opportunities and economic growth.

Whether traveling for business or pleasure, customers now have more – and easier – ways to join Delta in its work to fly more sustainably. Starting this month, Delta customers will be able to use the global airline’s upgraded carbon calculator to choose from four new carbon offset project options – each of which has verified emissions reduction impacts that align with United Nations Sustainable Development goals.

Delta led the U.S. aviation industry by launching the first carbon offset program in 2007, in addition to purchasing more than 12 million offsets since 2012 to achieve carbon-neutral growth ahead of CORSIA, the scheme that will limit international emissions to 2019/2020 levels. Now, the world’s most reliable airline is boosting its commitment with an updated tool that will also be available for the first time via the “More” tab in the Fly Delta app.

“We’re a global airline whose business is connecting people to each other and the world. Critical to that mission is caring for the environment,” said Alison Lathrop, Delta's Managing Director - Global Environment, Sustainability and Compliance. “Through thorough research and a careful selection process, we’ve chosen effective projects that our customers can feel comfortable and confident about when offsetting the footprint of their travels.”

How to offset travel for a solo traveler, large groups or companies

The calculator provides an option to enter single flight data, in addition to uploading bulk flights for events or travel for a larger group. Customers can either type origin and destination airports or upload a travel spreadsheet. Click “Calculate CO2 emissions” and, after that, “Offset now.” You’ll be able to read about four projects you can choose to support.

For example, the calculator shows an Atlanta-Los Angeles roundtrip flight covers 3,882 miles with an impact, for one person, of 0.508 metric tons of CO2. Offsetting the impact of that round trip ranges from $3.30 to $5.08, depending on the project chosen.

How do offsets help the environment? Jet fuel accounts for two percent of global greenhouse gas emissions. Carbon offsets reduce the CO2 in the atmosphere, helping to mitigate the impact of greenhouse gases. Each offset has a verified emissions reduction and advances United Nations Sustainable Development Goals.

Delta’s offsetting partners that measurably mitigate the impact of greenhouse gases:


This initiative will protect a critical part of the Cardamom Mountains Rainforest in Cambodia, one of the most important conservation locations on the planet. The Project will support 21 villages in an effort to nurture biodiversity and create alternative livelihoods.


Part of an initiative that has been protecting Kenyan forests since 2006, this megaproject addresses human-wildlife conflict on a large scale—it is estimated to reduce more than a million metric tons of CO2e per year.


Located on the Caribbean coast of Guatemala, this project protects the Mesoamerican Biological Corridor. These diverse ecosystems—an important source of income for local families—have suffered years of deforestation from farms and cattle ranches.


Over 90,000 farmers have planted, maintained, and monitored over 19 million live trees in Kenya, and Uganda—trees that are already reducing erosion, enriching soil, and providing sustainable environments and livelihoods for the TIST farmers as well as their families and communities.

Since 2005, Delta has reduced its jet fuel consumption, leading to an 11 percent decrease in emissions as Delta works toward its long-term goal of reducing emissions by 50 percent by 2050. Delta is also investing in new, more fuel-efficient aircraft to optimize the use of jet fuel. The carbon calculator is the airline’s latest way of allowing customers to join Delta in making an impact by investing in climate action as well as local communities.

Most recently, Delta invested $2 million in a feasibility study of a sustainable aviation fuel (SAF) production facility and flew its first of 20 carbon-neutral delivery flights using SAF and carbon offsets this summer. Delta is the only U.S. airline to voluntarily cap its carbon emissions at 2012 levels by purchasing over 12 million verified offsets and has removed a variety of single-use plastic items on board, from amenity kits and from Delta Sky Clubs.
