Several years ago we outgrew our space in Seattle and we made a conscious choice to invest in downtown Seattle—even though it would have been cheaper to move to the suburbs.

We now employ more than 40,000 people in Seattle who come from all around the world. Our employees tell us that they love being in the heart of the city. In fact, about 15% live in the same zip code as their office and about 20% walk to work. This is one of the many advantages of having an urban campus.

Our buildings in Seattle are sustainable and energy-efficient. The buildings' interiors feature salvaged and locally sourced woods, energy-efficient lighting and composting and recycling alternatives, as well as public plazas and pockets of open green space outside of the buildings. Twenty of the buildings in our Seattle campus were built using LEED standards.

The green roofs on our Doppler building and adjacent Meeting Center reduce building heating and cooling loads, clean and reduce storm water runoff by at least 70%, moderate the urban heat island effect and improve local air quality.

We joined the Department of Energy’s Workplace Charging Challenge, a public-private partnership to support the development of the national plug- in electric vehicle (PEV) infrastructure. We offer PEV charging stations for our more than 40,000 employees in Seattle.

And our newest buildings in the Denny Triangle area of Seattle are heated using an innovative approach to sustainability—recycling energy. This "district energy" system works by capturing heat generated at a non-Amazon data center in the neighboring Westin Building and recycling that heat through underground water pipes instead of venting it into the atmosphere. This unique approach is nearly 4x more efficient than traditional heating methods and will also enable the Westin Building data center to cut back on the energy it uses to cool its building.
