"Microsoft pledges to cut carbon emissions by 75% by 2030", 14 Nov 2017

At Microsoft...[w]e...have been taking steps to address and reduce our carbon footprint for nearly a decade. In 2009, Microsoft set its first carbon emissions target. In 2012, we became one of the first companies to put an internal global carbon fee in place, which enables us to operate 100 percent carbon neutral. Last year, we put in place targets to get more energy from renewable sources...

[W]e will take the next step in this journey by pledging to reduce our operational carbon emissions 75 percent by 2030, against a 2013 baseline. We’ll do this through continued progress against our carbon neutrality and renewable energy commitments, as well as investments in energy efficiency. This puts Microsoft on a path, as a company, to meet the goals set in the Paris Agreement...We estimate this will help avoid more than 10 million metric tons of carbon emissions per year by 2030...

...It’s our hope that this pledge inspires others to join us in setting targets, and provides confidence to governments, companies and individuals that it’s possible for entities to help reach the goals set in the Paris Agreement...
