Facing climate change

Greenhouse gas (GHG) emissions are a reality in the airline industry, but hot air doesn't have to be. JetBlue believes in communicating transparently about climate change in order to educate our customers and crewmembers.

We are actively reducing our GHG emissions through new engine technology, flying techniques, and know biofuels will be an important part of even more reductions in the future.

Just the facts, ma'am

  • Almost all climate scientists agree that GHG emissions are raising the average temperature of the earth. Anytime a fossil fuel is burned, GHGs such as carbon dioxide (CO2) are released. These gases trap heat in the atmosphere, altering the climate in ways that can impact almost every aspect of the way we live – from the beautiful places we love to visit to global agriculture and farming.
  • Air travel is one of many human activities that emit GHGs. But, contrary to popular belief, air travel actually accounts for only a minority percentage of total global GHG emissions – and there are ways to offset.

How we're making a difference

Our GHG emissions from every year of JetBlue's existence are publicly reported, and we have committed to meeting the International Air Transport Association (IATA)opens in a new window targets for GHG emission reductions. View emissions reportsopens in a new window.


We are part of the industry pledge to:

  • improve fuel efficiency 1.5% per year from 2009 to 2020
  • target a cap on net aviation CO2 emissions from 2020 (carbon-neutral growth);
  • and reduce net aviation CO2 emissions of 50% by 2050, relative to 2005 levels.

  • Our emissions intensity has dropped steadily since 2009 as our operations have become increasingly efficient. View sustainability reportsopens in a new window
  • We have added Sharklets – curved extensions to the wing that provide greater aerodynamic lift and improve fuel efficiency by roughly 3 percent.

  • We were the only airline to sign the American Business Act on Climate Pledge, and as a part of that researched and developed our renewable jet fuel commitment.

Renewable jet fuel

Renewable jet fuel is an important element for reducing aviation's impact on the global climate. Renewable jet fuel refers to jet fuel that can be produced from biological resources and can be replenished naturally and quickly (thus 'renewable'). When compared to traditional petroleum-based Jet-A, it significantly reduces emissions and environmental impact. Renewable jet fuel is chemically equivalent to conventional Jet-A and has no impact on performance or safety.

JetBlue is partnering with SG Preston, a bioenergy company, to purchase renewable jet fuel made out of biomass that does not compete with food supply. Each year for ten years, we will be purchasing 33 million gallons of blended renewable jet fuel (made of 30% renewable and 70% traditional fuel).With SG Preston, we're creating a fuel supply that has the ability to benefit our bottom line and lower CO2 emissions by up to 50% per gallon before it is blended.
