- Delta Air Lines CEO Ed Bastian said the company is going "fully carbon neutral" starting March 1.

Delta Air Lines CEO Ed Bastian told CNBC on Friday the company is going "fully carbon neutral" starting March 1.
"It's a big challenge and it's a big commitment," Bastian said on "Squawk Box."
Delta is committing at least $1 billion over the next decade to reduce environmental impact, focusing on clean technological investments for engines and carbon removal, he added.
"There's no greater challenge that I know of that we need to be investing in and innovating in as environmental sustainability," he said.
The company, which has made environmentally conscious moves in the past, will still rely on jet fuel.
"We will continue to use jet fuel for as far as the eye can see," Bastian said. "We'll be investing in technologies to reduce the impact of jet fuel, but I don't ever see a future where we'll eliminate jet fuel from our footprint."
Bastian stressed the company won't rely on carbon-offset programs, though it has purchased some in the past.
"Carbon offsets are not the solution, we need to be investing in projects that make a difference," he said. "That's not really helping our planet."
Airlines account for roughly 2% of global carbon dioxide emissions, and many have set plans to achieve carbon-neutral growth from 2020. Delta's announcement on Friday is the largest such commitment.
Delta's move comes at a time when many companies are reducing their environmental footprint to combat climate change.
In January, Microsoft unveiled an ambitious green plan aimed at making the company "carbon negative" this decade. By 2050, the company hopes to have removed as much carbon dioxide from the atmosphere as it's emitted since being founded in 1975.
BlackRock, with more than $7 trillion in assets under management, will put "sustainability at the center of our investment approach," from portfolio construction to launching new investment products that screen fossil fuels, Fink wrote.
