JetBlue has launched a programme to help corporate customers reduce business travel emissions and meet sustainability targets.
Biogen, Deloitte, ICF and Salesforce are the first customers to join the initiative.
JetBlue's Sustainable Travel Partners program offers participants sustainable aviation fuel certificates.
The carrier currently uses SAF on routes from San Francisco International Airport and Los Angeles International Airport.
JetBlue also plans to provide emissions data based on travellers' actual flights and the carrier's average fuel burn on those routes.
The airline is working to include travel emissions data into Salesforce's Net Zero Cloud tool for those in the Sustainable Travel Partners program, according to the company.
JetBlue also said it would help customers develop strategies to reduce emissions associated with their business travel, and participants would receive carbon offsetting on domestic flights operated by JetBlue.
Airlines in Europe have also launched sustainability initiatives for corporate customers with Air France-KLM unveiling its “Sustainable Aviation Fuel” programme for corporate customers a year ago.
The scheme enables customers to make an annual contribution to a Corporate SAF programme based on their estimate of travel-related CO2 emissions.
Lufthansa, meanwhile, expanded its Compensaid initiative to corporate customers last April enabling them to offset CO2 emissions from flights to help them achieve sustainability goals.
Heathrow Airport recently announced a plan to enable travellers to offset emissions by purchasing SAF via an online platform.
Some corporates, such as Microsoft, have struck deals directly with airlines to buy sustainable fuel credits to offset travel.
