Facebook has promised to use only wind and solar energy to power its global tech operations in a major drive to cut its emissions by the end of the decade.

The world’s largest social media group said it plans to cut the greenhouse gas emissions from its energy-intensive data centres by using only renewable power by the end of 2020.

The tech titan raised its clean energy ambition after beating its target to support 50pc of its facilities with renewable energy by 2018 a year early.

By cleaning up its energy use Facebook hopes to slash its greenhouse gas emissions to a quarter of where they are today.

Technology giants are increasingly taking up the global fight against climate change to combat their growing carbon footprint of their data centres.

Last year 62pc of Facebook’s total greenhouse gas emissions were due to data centres alone, most of which are found on the west coast of the US in Oregon.
