2025 update
With our current five-year Sustainability Action Plan concluding in 2024-2025, we are set to begin the next phase of our sustainability efforts. The University will develop a new plan that will guide us towards our 2050 sustainability objectives. This plan will address the needs of our tri-campus community and involve a range of partners in its creation.
Stay informed about progress, learn about the planning process, and discover ways to get involved on the Sustainability Action Plan update page.

10% LESS SOLID WASTE BY 2025
Everything we throw away is something that we don’t need. That may seem self-evident, but combined with life-cycle thinking it means an opportunity to reduce manufacturing emissions, energy consumption, transportation, and even raw materials extraction associated with whatever object we didn’t need. “Reduce, reuse, recycle” remains a powerful hierarchy of solid waste management, but there are even more details of product and materials management, economics, and urban ecology that can receive both our research attention and our operational attention.
Status updates
2020-2025 wrap-up report
Progress:
- Converted eight Seattle academic buildings to single-stream recycling with centralized compost collection and improved signage.
- Piloted a reusable cup program at Alaska Airlines Arena.
- Piloted donation drives to promote reuse of furniture and other items during residence hall move-outs.
- Released UW’s first Zero Waste Assessment Report, establishing a baseline for waste generation and diversion.
- Launched contamination-prevention outreach campaigns in residence halls to improve recycling and compost quality.
- UW Bothell installed smart sensors to optimize waste collection routes.
- Tacoma explored waste reduction strategies through student-led living lab projects.
By-the-Numbers:
- In 2022, solid waste contributed 0.6% of UW’s total greenhouse gas emissions, a small but highly visible component of the footprint.
- The “Give & Go” move-out pilot at Bothell diverted 800+ pounds of material in its first year.
- Seattle campus 2023 Data:
- 50.2% diversion rate (2,501 tons recycled, 1,896 tons composted, 1,444 tons reused).
- 5,783 metric tons sent to landfill or incineration.
- About 348 pounds of waste per person (students + employees).
Status: Not achieved. UW diverted over 50% of its waste in 2023, surpassing national averages and reflecting strong recycling, composting, and reuse programs. However, total non-hazardous waste generation reached 11,624 metric tons, showing no decline from the 2019 baseline. Landfill and incineration tonnage also rose about 20%, against a goal of a 10% reduction by 2025. These results highlight the need to shift from managing waste after it is created to reduce waste at the source, which will be a priority in the next Sustainability Action Plan.
