How Delta will cut its carbon footprint

Ed Bastian, Delta Air Lines’ C.E.O., will announce this morning an ambitious plan to become the first U.S. airline to go carbon neutral. The company pledges to spend at least $1 billion over the next decade to buy emission offsets and invest in more efficient planes, new fuel sources and carbon-capture technologies.

The bulk of its money is most likely going toward offsets, because the industry will be reliant on fossil fuels for the foreseeable future. (After all, Elon Musk hasn’t proposed building electric planes just yet.)

Andrew’s take: This is a huge step that will probably generate public good will for Delta and put pressure on other airlines, many of which probably can’t afford similar programs. But the sustainability of buying offsets for a decade is an open question. Also, what constitutes an offset and how to measure and meaningfully track their progress will be a challenge. And what happens when the economy sags, or Mr. Bastian is no longer C.E.O.? Will the program survive?
