1 Biofuel
Airline companies have begun experimenting with carbon-neutral biofuels. These fuels can cut carbon emissions, but they have yet to be mass-produced for use.
2 Traffic control
New precision-based navigation systems will allow airlines to fly more directly to their destination, using satellite signals. Shorter flights mean less fuel burned–and fewer emissions.
3 Efficiency
New plane designs, like Boeing’s Dreamliner, get more miles to the gallon. Airlines are also trying to go light–every 5.5 lb. of weight reduced saves a ton of carbon emissions per year.
A NEW CLASH
The latest ugly police encounter with African Americans to go viral unfolded in the Dallas suburb of McKinney, where officer Eric Casebolt arrived “out of control,” in the words of his chief, to a complaint about a June 5 pool party at a private subdivision. Casebolt waved his gun at a group of teenage boys, then shoved a bikini-clad 14-year-old girl already complying with his orders onto the ground. A white partygoer recorded it all unmolested, and Casebolt resigned four days later.
