JetBlue plans to offset carbon dioxide emissions on all its domestic flights as of July, the carrier announced. With its partner, Carbonfund.org, JetBlue estimates it will add offsets to between 15 billion and 17 billion pounds of emissions per year. JetBlue has worked with Carbonfund.org over the past decade to "balance customer flying during specific times of the year," and the carrier estimates it has offset more than 2.6 billion pounds of emissions since 2008. Offset projects that JetBlue plans to support include forest conservation projects, landfill gas capture programs and the development of solar and wind farms. JetBlue CEO Robin Hayes said in a statement that the offsets are "preparing our business for the lower-carbon economy that aviation, and all sectors, must plan for." In addition, JetBlue this year will begin using a lower-carbon fuel, produced from waste and residue raw materials, on flights from San Francisco.
