The arena, home to the city's incoming NHL franchise and WNBA's Storm, will be powered 100% by renewable electricity and seek to achieve a zero carbon footprint. Amazon founder and CEO Jeff Bezos broke the news Thursday on Instagram.

NHL Seattle CEO Tod Leiweke said in an interview Thursday that the arena aims to produce zero waste, will source food locally and reduce all plastics by 2024.

He said the team had long been looking into increasing "sustainability" within the arena, but added that the Amazon deal takes things to a different level.

'We were talking about Amazon and talked about community," Leiweke said. "And they came back and said, 'Look, the No. 1 community cause for us and what we believe in most is climate and Jeff's commitment to the climate pledge.' And we came away inspired."

What resulted, he said, was something NHL Seattle, the Oak View Group (OVG) arena developer and Amazon all felt could give the city something bigger to believe in during these trying times.
