Azure sustainability

Help build a clean-energy future and make progress toward your sustainability and business goals.

Sustainable cloud infrastructure with a local impact

At Azure, we see sustainability and humanity's response to climate change as one of the greatest challenges of our lifetime.

We believe it’s not too late to plan for a cleaner, greener future. We’ve committed to put sustainable technologies at the heart of our innovation—to make sure we are adapting and growing along with the planet with the lowest environmental impact.

Learn how you can join the global community committed to reducing energy use, transitioning to a more carbon-neutral grid, and promoting a greener future with sustainable and innovative technologies from Azure.

The Carbon Benefits of Cloud Computing

A 2018 study found that using the Microsoft Azure cloud platform can be up to 93 percent more energy efficient and up to 98 percent more carbon efficient than on-premises solutions.

Evolving beyond an operational approach

Sustainability is often viewed from an operational point of view, with the environmental mission treated as a cost center in the business, as a risk or compliance to be managed. But for Azure, datacenters and sustainable cloud infrastructure are more than just business—they provide an incredible opportunity to give back to the communities where we operate.

Azure has committed to focus on four key areas of environmental impact to local communities—carbon, water, waste, and ecosystems.

Giving back to local communities

With sustainability at the core of Microsoft’s business, we’ve extended our goals for environmental sustainability beyond just how we operate datacenters. We’re actively engaged in over 40 projects around the world to help make a local impact and improve environmental outcomes.

Here are some examples:

Exploring energy innovations for the next generation of sustainable cloud technology

Learn how new server cooling methods can help minimize the environmental impact of physical datacenters—reducing energy use while providing higher processing power and helping to eliminate water consumption.

Find out how small steps like implementing grid-interactive UPS batteries—together with adding capacity and reducing the demand on the grid—can make a big difference to help us meet our sustainability goals and reduce our carbon footprint.

See how a switch from traditional diesel to less-carbon-intensive fuels to run datacenter backup generators helps to reach net-zero carbon emissions.

Johnson Controls changes energy use with edge devices

"We knew that if we could bring those digital controls that were typically on-premises to the cloud, we could extend them out to consumer devices like smartphones."

Frequently asked questions

  • Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human time scale—such as solar energy, wind power, hydroelectric power, geothermal energy, tidal power, and biofuels. By 2025, Azure will shift to 100 percent supply of renewable energy, meaning that we will have power purchase agreements (PPA) for green energy contracted for 100 percent of carbon-emitting electricity consumed by all our datacenters, buildings, and campuses.
  • Azure, as a part of Microsoft, has been 100 percent carbon neutral since 2012. This means we are removing as much carbon each year as we emit, either by carbon removal (carbon offsetting) or reducing carbon emissions.
  • This means that by 2030, we want to remove more carbon each year than we emit. By 2050, our goal is to remove all of our historical carbon emitted—either directly or by electrical consumption—since Microsoft was founded in 1975.
