Microsoft has revealed plans to accelerate its fights against the company’s own carbon footprint.

CNET reports that amid growing anxieties around climate changes effects - and the limited time left to act - Microsoft has ramped up its own efforts to curb its impact on the environment.

The tech giant revealed yesterday that it was speeding up plans to move its data centres to 100 per cent renewable energy, aiming for 75 per cent by 2023 - 5 per cent more than originally planned.

Microsoft is also raising its internal carbon fee from $8-to-$10 to $15 per metric ton for all business divisions. The levy was introduced in 2012 to encourage more financially (and ethically) responsibility for carbon emissions.

"The magnitude and speed of the world's environmental changes have made it increasingly clear that we must do more, and today Microsoft is taking steps to do just that," said president and chief counsel Brad Smith in a statement.

"We're taking action to put our own house in order, while increasingly addressing sustainability challenges around the globe by engaging our strongest assets as a company - our employees and our technologies."
