The Office of Sustainability & Environment (OSE) collaborates with a wide range of internal and external stakeholders to develop innovative environmental solutions that foster equity, vibrant communities and shared prosperity. Information on OSE's work as well as Seattle's citywide environmental programs is also included in this site.


City Bldgs Report Cover

Energy Use of City Buildings
Seattle Municipal Buildings 2013 - 2014 Energy Performance Report lists the annual energy use per square foot of all City-owned buildings 10,000 square feet or larger and smaller public facilities such as libraries.

EBR Report Cover

Energy Use of  Private-Sector Buildings
Building Energy Benchmarking Analysis Report 2013  includes key findings from an analysis of 281 million square feet of Seattle's largest buildings required to annually report energy performance (buildings 20,000 square feet and larger). Seattle continues to raise the bar nationally, with 99% of required building owners now measuring their energy use and understanding their energy performance relative to similar buildings.

New Energy Policy Development
To further energy efficiency action in the building sector, the Office of Sustainability & Environment is collaborating with City departments and the community to develop new incentives, programs and requirements that will help building owners achieve the energy savings needed for Seattle to meet our climate goals. More information on that work here. 

EBR Dashboard

New Energy Dashboard for Private-SectorSeattle is committed to helping building owners and managers create more efficient buildings.  Explore this new online tool that allows building owners to compare the efficiency of their facilities with local and national benchmarks.

The Office of Sustainability and Environment delivers cutting-edge policies and effective programs to address Seattle's environmental challenges while creating vibrant communities and building shared prosperity. Visit the Key Initiatives page to see a list of all the program focus areas for our office.

More examples for each area below can be found in our 2013 Accomplishments Report.


We develop and test forward-looking approaches. For example, following three years of focused effort by OSE, Seattle is poised to be one of the first cities in the United States to develop a district energy system that uses waste heat from sewer lines and data centers to heat buildings.


We deliver measurable results that advance the City's environmental goals. For example, OSE worked with its partners to launch the second year of Fresh Bucks, a program that doubles the purchasing power of low-income residents at Seattle farmers markets. In its second year, Fresh Bucks helped more than 2,500 low-income residents buy healthy produce at Seattle farmers markets.


We create bold and strategic action plans for achieving Seattle's environmental goals. OSE worked closely with Seattle Public Utilities to develop and adopt Seattle's first community-wide implementation goal for green stormwater infrastructure: managing 700 million gallons of stormwater runoff annually with green infrastructure by the year 2025.

Seattle faces many of the same challenges as the broader US environmental movement: those who shape and benefit from environmental policies and outcomes are primarily white, upper-income communities despite the fact that people of color, immigrants, refugees, and people with low incomes often bear a disproportionate burden of environmental impacts.

We need to ensure the benefits of a healthy environment are shared by all Seattle residents. 

To address these disparaties, Seattle has launched the Equity & Environment Initiative (EEI).

The EEI is both a "look under the hood" to understand who is and is not benefiting from Seattle's environmental progress and an effort to lift up community based solutions and create opportunities for new leadership in Seattle's environmental movement. In the first year of the EEI, we will create an Equity and Environment Action Agenda in partnership with the community and funders to advance racial equity in Seattle's environmental work.
