We're responding to climate change by taking action to mitigate our greenhouse gas emissions and investing in a resilient water system. Learn about our past and present emissions, carbon footprint reports, and our strategy for reaching net zero greenhouse gas emissions by 2050.

Net Zero Strategy

At the Portland Water Bureau, we’re not just dedicated stewards of our region’s water supply—we’re also fierce advocates for reducing greenhouse gas emissions. That’s why we’re committed to cutting our greenhouse gas emissions in half by 2030 compared to a 2007 baseline, and to reaching net zero emissions by 2050. (Net zero is defined as the state where greenhouse gasses, including carbon dioxide, nitrous oxide, and methane, are added to the atmosphere and removed from the atmosphere at equal rates.)

This work is aligned with the City of Portland’s Climate Emergency Declaration and City climate goals. In 2024, the Water Bureau published our first Net Zero Strategy outlining steps we need to take to reach our net zero goal. 

Over the next five years, we’ll be focusing our greenhouse gas reduction and mitigation efforts on the following subset of high-priority actions:

Top strategies for the next five years (through fiscal year 2028–29)

  • Reduce electricity use through energy savings contracts and programs, preventing water loss, and climate-smart planning and design practices.
  • Increase renewable energy generation by looking for new solar and micro-hydro opportunities.
  • Reduce fleet emissions by transitioning to electric and high-efficiency vehicles. 
  • Begin phasing out natural gas by switching to electric heating sources.
  • Increase both internal and external communication and partnership around climate action.
  • Analyze scope 3 emissions and identify opportunities for meaningful emissions reductions.
  • Use an adaptive management approach to update our Net Zero Strategy regularly. Continuously conduct research and incorporate new projects into our strategy as appropriate.

Greenhouse gas emissions dashboard

We’re working to cut emissions in half by 2030 and to reach net zero emissions by 2050. To increase transparency and accountability around our climate efforts and progress toward net zero goals, we made an interactive dashboard showing organizational emissions, sources, and trends.

Carbon footprint reports

We’ve been tracking and reporting on the bureau’s greenhouse emissions since 2007 in regular carbon footprint reports. These reports calculate annual emissions and summarize historical trends in emissions, with a focus on scope 1 and 2 emissions and renewable energy generation. Recent carbon footprint reports can be found here:

Climate adaptation and resilience

We’re a national leader in water sector climate adaptation and have a long history of planning for climate impacts to Portland’s water supply and distribution system. Read more about how we adapt to climate impacts and build resilience to physical and organizational climate risks and stressors.
