By 2030, we will be carbon negative, and by 2050, we will remove from the atmosphere all the carbon dioxide we have emitted since we were founded in 1975.

What are they doing about it?

Renewable Energy Use

By 2025, we will reach our 100 percent renewable energy goal by purchasing enough renewable energy to match our electricity consumption at our datacenters, buildings, and campuses worldwide. We are well on our way to reaching this goal, as we began purchasing renewable energy via long-term power purchase agreements (PPAs) in 2013, and have steadily signed more deals in subsequent years, purchasing renewable energy across three continents.

Renewable Energy Generation

We utilize on-site energy when it makes sense. For example, we currently power 25 percent of our Silicon Valley campus from on-site photovoltaic panels. Our Puget Sound campus has been powered by zero carbon Washington hydropower since 2019.

Energy Efficiency

We established our internal carbon fee in 2012 to fund our carbon neutrality commitment. In 2019, we raised the fee to $15 per ton, which we charged to each business group across Microsoft based on their Scope 1 and 2 carbon emissions and business air travel. In FY20 we reduced emissions across all scopes by 586,683 metric tons of CO2e.
