Amazon has announced a pledge to invest $2 billion in clean energy companies “whose products and services will facilitate the transition to a zero carbon economy.” The company is setting up a dedicated venture investment program with an initial backing of $2 billion to specifically invest in clean energy companies. The new venture fund builds on previous climate change efforts by Amazon, which include a $100 million climate venture fund, renewable energy projects, and an overall plan to run on 100% renewable energy by 2025. In September of last year, Amazon committed to ordering 100,000 electric delivery vehicles from Rivian, an electric vehicle upstart it’s also invested in.

The $2 billion fund, the Climate Pledge Fund as it’s named, will invest in multiple industries, including energy generation, manufacturing and materials, food and agriculture, transportation and logistics. Amazon also says it’ll seek opportunities to involve other companies in the venture fund.

“The Climate Pledge Fund will look to invest in the visionary entrepreneurs and innovators who are building products and services to help companies reduce their carbon impact and operate more sustainably,” Amazon CEO Jeff Bezos said in a statement. “Companies from around the world of all sizes and stages will be considered, from pre-product startups to well-established enterprises. Each prospective investment will be judged on its potential to accelerate the path to zero carbon and help protect the planet for future generations.”
