The Office of Sustainability & Environment (OSE) develops and implements citywide environmental policies and programs that propel our city toward a sustainable, equitable, and carbon neutral future. We collaborate with a wide range of stakeholders to develop innovative environmental solutions that foster equity, vibrant communities, and shared prosperity. 

Program Highlight: Duwamish Valley Program

Seattle's Duwamish Valley Program is a multi-departmental collaborative effort led by the Office of Sustainability & Environment (OSE) and the Office of Planning and Community Development (OPCD) to advance the City's environmental justice and equitable development goals in the Duwamish Valley, with an emphasis in the South Park and Georgetown neighborhoods.  

Program Highlight: Seattle Resilience Strategy
How can Seattle continue to thrive amidst ongoing urban challenges, prepare for sudden shocks and catastrophic events, and create opportunities for all residents to enjoy a prosperous, healthy, and high quality of life? This is what the Seattle Resilience Strategy is all about. 


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.

The report highlights Seattle's progress towards goals in environmental categories such as climate, building energy, transportation, food, trees and green space, complete neighborhoods, and healthy environment and shows continued progress toward our goal of being better stewards of the environment and fighting climate change. 



Our actions today determine how much climate change will impact future generations. Seattle is leading the development of climate solutions even as we also prepare our residents and businesses for the climate impacts they are likely to experience.

OSE develops policies and implements programs that reduce climate pollution from our transportation and building sectors. OSE also provides guidance on how Seattle can minimize disproportionate climate impacts on our most vulnerable populations.


In Seattle, like in most cities, 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.

OSE is leading the City effort to shift our approach so those most affected by the combined impact of hazardous pollutant exposure, climate change, and racial-socio economic conditions will lead on designing solution and directly benefit from our investments.


In order to ensure future generations in Seattle enjoy the same benefits as today's residents and businesses, it's critical to protect and enhance our natural environment, preserve and improve public health, and reduce pollution in our waterways and Puget Sound.

OSE coordinates Citywide work for increasing access to local and healthy food; preserving open space and growing our tree canopy; and managing our stormwater runoff in a way that maximizes ecological and neighborhood benefits.

The Equity & Environment Initiative is a partnership of the City, the community, local and national foundations. The EEI is an ongoing commitment to "look under the hood" to understand who is and is not benefiting from Seattle's environmental progress with a focus on lifting up community based solutions and creating opportunities for communities of color, immigrants, refugees, people with low-incomes and limited-English proficiency individuals to be leaders in Seattle's environmental movement.

On Earth Day 2016, OSE released Seattle's first ever Equity & Environment Agenda, a blueprint to advance race and social justice in Seattle's environmental work.
