Delta Airlines announced earlier this month plans to be the first global airline that is completely carbon neutral, according to WABE in Atlanta.

Delta CEO Ed Bastian laid out an ambitious timeline for making it happen.

“We’ve committed, starting March 1, to fully offset our emissions — the footprint we create from our jet fuel and other emissions — our carbon footprint as an airline. We’ll be making investments. We estimate it’s going to be about a billion dollars over the next decade.”

That money will fund developments in technology, allowing Delta to increase its planes’ efficiencies while reducing fuel consumption.

To offset the CO2 its jets will still produce, Delta says it will invest in forestry, wetland restoration and grassland conservation, among other things.
