Heather Goldstone, chief communications officer at the Woods Hole Research Center, spoke with Boston Public Radio on Thursday about Jeff Bezos' new $10 billion Earth Fund. Bezos is the CEO of Amazon, a company that emitted 44.4 million metric tons of carbon dioxide in 2018. He pledged that the fund will help combat climate change.

"There's been some mixed thought about this, it's really unclear what this fund actually will be," Goldstone said. "I think it's this pressure to demonstrate 'What are you doing?' in this space and if in fact we're looking at a $10 billion investment in solutions oriented research and deployment, that can only be a good thing."

Hundreds of Amazon workers have criticized the company for it's work with oil and gas companies.

"That's another caveat with [Bezos' pledge] — is this genuine or an attempt to quiet that internal discontent?" Goldstone said. "This is a sign that there is strong pressure in the right direction."
