Operating to drive global change

We've been setting a price on carbon that is charged across the company since 2012. With the funds collected from this internal carbon tax, we have reduced energy consumption, increased our purchasing of clean energy, and invested in offset projects for the carbon we can’t reduce or replace. In 2017, Microsoft pledged to reduce its operational carbon emissions 75 percent by 2030 and is on target to achieve this goal.

Carbon principles

Our facilities

We have reduced carbon emissions on our corporate campus in Washington state to cut energy use by more than 20 percent.

Our power

We are one of the biggest green buyers of energy in the U.S. and have purchased more than 21 billion kilowatt hours of green power globally.

Our suppliers

We are working with suppliers to encourage them to report—then reduce—their emissions.

Our technology

We are using the cloud and AI to further reduce our own emissions, and help customers track, assess and reduce their carbon footprint.
