We recognize our business has an impact on the planet. We are working to better understand, track, and quantify our environmental footprint as we enable more circular commerce.

GHG By Source (MTC02e)

Greenhouse Gas Emissions

In 2018 eBay’s carbon footprint was 122,191 metric tons of carbon dioxide equivalent (MT CO2e)—down 8 percent from 2017 even as our business grew. The decrease is primarily due to more efficient energy management, including sourcing more renewable electricity to power our eBay-owned data centers. Data centers comprised 68 percent of our footprint, with offices and business travel contributing the other 32 percent.

2016 and 2017 data have been restated to ensure consistency with CDP and RE100 reporting requirements. These figures replace previously published data. Some segments do not add up to totals due to rounding.

GHG (Scope 1 and 2—Market-Based)

GHG (Scope 1 and 2—Market-Based)

Another way to look at carbon emissions is through the classifications used in the World Resources Institute’s Greenhouse Gas Protocol. This approach categorizes emissions into “Scopes”—Scope 1 is carbon emitted directly by eBay; Scope 2 is emissions resulting from the grid electricity eBay consumes. eBay has a corporate goal to achieve 50 percent absolute reduction in Scope 1 and 2 GHG emissions by 2025 and 75 percent reduction by 2030 from our 2016 baseline. Scope 1 emissions and Scope 2 emissions decreased by 6 percent between 2016 and 2018, due primarily to more efficient use of energy to power our data centers and offices and transitioning to more renewable sources.

Total Energy Use (MWh)

Energy Use

All businesses have an impact on the environment. And, like for many companies, eBay’s largest environmental impacts are the result of its energy use. eBay’s overall energy use increased 1 percent between 2017 and 2018, while total electricity use decreased slightly even as our business grew. This was due primarily to more efficient use of energy to power our data centers and offices. Power usage effectiveness (PUE) at eBay-owned data centers improved by 0.5 percent from 2017 to 2018, and eBay’s Salt Lake City-based data center (SLC02) earned the ENERGY STAR® for Data Centers Label in 2018 for its efficient design and operations. And, while the IT load at colocated data centers increased by 13 percent from 2017 to 2018, the actual energy consumption decreased by 6 percent, reflecting a more efficient portfolio. Our smart metering programs in Europe and the Middle East have enabled eBay to reduce total electricity consumption at six office sites in 2018 compared with 2016, even as the number of employees increased at these locations.

Total Electricity Mix

Renewable Energy

As a member of RE100, eBay has set a goal to use 100 percent renewable energy in our electricity supply by 2025 at eBay-controlled data centers and offices. We are on track to achieve this goal by participating in local utility-driven green power programs, such as Solar Choice in San Jose, Calif. We also actively pursue power purchase agreements (PPAs), and are assessing the feasibility of other onsite renewables in addition to our solar array in Salt Lake City, Utah.

Water Consumption (kGallon)

Water Consumption

Water is an increasingly precious resource worldwide, and this is only expected to intensify as the climate changes. eBay works to conserve water every day, and many of our sites have implemented water-saving technologies and processes. We’re now working to build a more robust system for tracking and managing water company-wide. In 2018, we used about 101 million gallons of water, a 10 percent decrease from the year before. This includes our owned data center location, as well as our large office locations. The decrease was due primarily to improved energy management plans at our managed and colocated data centers, including improving water usage effectiveness (WUE) at eBay-owned data centers by 54 percent from 2017 to 2018.

2016 and 2017 data have been restated to reflect collection of additional activity data and improved estimation techniques. These figures replace previously published data.

A note about assurance

In accordance with ISO 14064-3 on GHGs – Part 3: specification for guidance for the validation and verification of GHG assertions, external assurance provider Bureau Veritas North America (BVNA) performed a limited assurance of Scope 1 and 2 greenhouse gas emissions in addition to Scope 3 business travel.
