Inc. boosted its role as the world’s biggest corporate buyer of green power with a series of deals to help slash the company’s carbon footprint.

Agreements to buy renewable energy are an increasingly popular way for big companies to cut emissions. Amazon will use the power from wind farms, solar parks and batteries to run its global operations.

“Many parts of our business are already operating on renewable energy, and we expect to power all of Amazon with renewable energy by 2025 -- five years ahead of our original target of 2030,” Jeff Bezos, Amazon’s chief executive officer, said in an emailed statement. The company has committed to having net-zero emissions by 2040.

As of June last year, Amazon sourced about 42 per cent of its global energy needs from renewables.

The series of deals in the U.K., Sweden, Spain, the U.S. and Canada will add more than 1.5 gigawatts of capacity to Amazon’s network of green power supplies. In total, the company will source enough renewable energy in Europe to power the equivalent of more than two million homes a year.

All of the projects are new developments that will take a couple years to start generating power. They include 350 megawatts from a wind farm off the coast of Scotland, 258 megawatts of power from a wind farm in northern Sweden and 100 megawatts of solar power in California with an additional 70 megawatts from an attached battery facility.

The terms of deals weren’t disclosed, nor were the owners of the renewables projects.
