We have offices in more than 70 countries and territories around the world, and we are powered by 16 major data centers, which are leased in the U.S., the U.K., Switzerland, the Netherlands, Germany, Singapore, Russia, Hong Kong and China.
With a commitment to measuring and understanding our carbon footprint, this year we conducted our first enterprise-wide audit of our energy use and greenhouse gas emissions. The results will allow us to measure the impact of operations and help us identify our priority areas to address in the coming years.
Nearly all of our energy use and emissions are from electricity use in our leased office spaces and data centers. In calendar year 2017, our total Scope 1 and Scope 2 GHG emissions were estimated at 51,335 tonnes of CO2e. Electricity use in our leased data centers and office spaces contributed to almost 90% of our carbon footprint, with data centers representing nearly half and our offices representing 40% of our impact. The remaining 12% of GHG emissions are from our customer service centers located throughout the world. Among the 16 data centers we operate globally, 73% of energy use for data centers is from our Amsterdam and Slough, England, locations.
Because we lease our office spaces and data centers, we are limited in our ability to address the source of our energy use directly. Our purchase of renewable energy reflects what is available for purchase in the electricity grid in the countries where our office spaces and data centers are located.
Across our offices, we engage with property managers to implement energy efficiency programs and incentives. Meanwhile our largest business, Booking.com, is developing a building for its headquarters. This will be the first building owned by any of our brands with the aim to be accredited with a Building Research Establishment Environmental Assessment Method (BREEAM) excellent certificate, giving us more direct control over our energy-efficiency initiatives.
Our highest source of water consumption comes from our data centers, and because we lease all of our data centers, we do not have access to the data on water use. But across our offices, we are reducing our water use through a number of water efficiency initiatives, such as installing low-flow and automatic faucets.
The majority of our waste impact is related to standard office operations. Each brand manages waste independently in accordance with regulations in each country of operations. Booking.com implements building design principles that reduce construction waste and incorporate waste separation in all offices supported by the local destination. OpenTable’s San Francisco office partners with a company to collect e-waste such as old monitors, keyboards, cables, servers, and desktops—and both of its Denver locations utilize their respective buildings’ e-waste recycling programs. Across North America, OpenTable works with a partner to pick up all recyclable electronic items.
