The Sustainability Office undertakes initiatives designed to make Portland a vibrant, environmentally friendly community now and into the future. We collaborate with all departments to increase the efficiency of City operations and seek innovative approaches to improve municipal services. We partner with community organizations, citizens, and businesses working to conserve energy, reduce waste, and preserve our natural resources. We promote actions that will make Portland resilient in the face of a changing climate.

News - Council Declares a climate emergency

On Monday, November 18 the City Council voted unanimously to support a Declaration of Climate Emergency.  It commits the City to work to eliminate greenhouse gas emissions by 2030.  Young people who participated in the international climate strikes on September 18 brought the resolution to the Sustainability and Transportation Committee on October 16. Committee members recommended it to the full council with a unanimous vote of 3-0. This means that our One Climate Future plan will identify opportunities to implement aggressive community wide greenhouse gas reductions within the next ten years.
