Salesforce leverages the power of our people and products to reduce the impact we and our customers have on the planet. From how we deliver our products to our focus on renewable energy, Salesforce incorporates sustainability in all aspects of our business.

Our multi-tenant cloud platform makes it possible to use a remarkably small number of servers as efficiently as possible. In fact, our core platform is 98% more carbon efficient on average than on-premises software. By moving to the cloud, our customers avoided emitting over one million tons of carbon in fiscal year 2015.

Transparency is important to us, which is why we update our key environmental metrics every year. See below for our fiscal year 2015 highlights.

Total Energy

We are actively working toward powering 100% of our global operations with renewable energy. Salesforce used a total of 101,041 MWh of electricity in FY 2014 and 140,278 MWh in FY 2015.

By Type

  • Nonrenewable energy sources 66%
  • Renewable energy credits 15%
  • Clean & renewable energy purchased from the grid 19%

Operational Efficiency

Power Usage Effectiveness (PUE) is a metric used by the tech industry to track data center energy efficiency. As an example, a PUE of 2.0 means that, for each watt of computing equipment power used, another watt of power is required for cooling and other supporting infrastructure. Similarly, CUE is used to track carbon efficiency and is measured in kilograms of carbon emissions per kilowatt-hour. For FY15, Salesforce's core platform had a CUE of 0.58.

Power Usage Effectiveness

  • Ideal 1.00
  • Industry Average 1.70
  • Salesforce 1.42

In FY 2015, our platform supported an average of 2.3 billion transactions every business day, up from 1.5 billion in FY 2014. Each transaction represents an action taken by a user, such as an edit to a contact record. It takes energy to process these transactions. Because of our commitment to energy-efficient architecture, we’ve kept the average amount of carbon (CO2e) produced per transaction steady at 0.07 grams in FY 2014 and FY 2015.

Building Green

LEED stands for green building leadership. See how we’re building for a better planet.



Salesforce Tower in San Francisco will be certified LEED Platinum.

We continually refine our greenhouse gas accounting processes. When new or better-quality data becomes available, we update our footprint data accordingly. Some data in this report has been restated from previous public disclosures.
