Amazon boss Jeff Bezos has pledged $10billion ($NZ15.6 billion) to help fight climate change.
The world’s richest man said the money would finance work by scientists, activists and other groups.
He said: “I want to work alongside others both to amplify known ways and to explore new ways of fighting the devastating impact of climate change.”
Mr Bezos has an estimated net worth of more than $130bn, so the pledge represents almost 8% of his fortune.
He announced the pledge on his Instagram page saying:
”Climate change is the biggest threat to our planet. I want to work alongside others both to amplify known ways and to explore new ways of fighting the devastating impact of climate change on this planet we all share. This global initiative will fund scientists, activists, NGOs – any effort that offers a real possibility to help preserve and protect the natural world.
“We can save Earth. It’s going to take collective action from big companies, small companies, nation states, global organisations, and individuals.
”I’m committing $10bn to start and will begin issuing grants this summer. Earth is the one thing we all have in common – let’s protect it, together.”
