Increase the green in 2016: Simplify

This new year, include simple changes for health and happiness with sustainable resolutions that stick.


Make kitchen composting easier by getting food scraps from the kitchen to the curb with a compost pail that meets your specific needs. Your perfect container may be as simple as a yogurt tub or as fun as a hand-painted canister. There are a variety of creative kitchen compost containers to fit your space and style. You may even be able to use something you already have around the house.

Here are a few ideas:

  • For a smaller household, an empty quart-size yogurt container works well for collecting food scraps and cleans up easily in the dishwasher.
  • A bucket with a lid can work well for a larger family.
  • Make some room for it under the kitchen sink or store it next to the garbage can.

Looking for something stylish that you can keep on your kitchen counter? Options abound in the housewares department of many local stores. You can also read about eight options to help you find the right kitchen compost container

Increase the green in 2016: Declutter

iconClear your home of unwanted electronics by giving away, donating or recycling items. Here are some options and resources to reuse or properly dispose of electronics.

Give away still working, but outdated (to you) items by listing them for free on a community social media platform. Options include Buy Nothing Project and Freecycle, to name a few.

Donate your used technology to a local organization like Free Geek. This nonprofit accepts most electronics and you can also purchase refurbished items in their thrift store. Use the Find a Recycler tool for your electronics that are still in good working order by clicking on the reuse/donate option to see locations near you.

Recycle specific items through Oregon E-Cycles, a free electronics recycling program for computers, phones, monitors, TVs, printers, keyboards and mice.

You can recycle a maximum of seven items at a time at one of the 50 collection facilities and recyclers in Portland.

Proper disposal is key for any electronics. Computers, monitors and TVs are not allowed in curbside garbage and cannot be disposed of at landfills or incinerators.

Bonus: If your gadget needs a repair you might be able to fix with expertise at a local Repair Café event.

From BPS Director Susan Anderson: From Portland to Paris, cities deliver on climate action

With an international climate agreement now in hand, we find much of the action ultimately is local.

As we welcome this New Year, I am excited and hopeful for Portland’s future. Over the last 12 months, the Bureau of Planning and Sustainability worked with many of you or your organizations to build plans, enact new policies, research and develop new technologies, and provide technical assistance to create a more prosperous, healthy, equitable and resilient city. 

In 2015, Council adopted an award-winning Climate Action Plan that will take our local leadership to new heights. You’ve also helped us take significant steps towards the completion of the state-mandated Comprehensive Plan. Much more than simply a map and new City Code, the 2035 Comprehensive Plan provides a framework to create financing, zoning and regulatory tools to achieve our most critical goals: a low carbon economy, more jobs, affordable housing, a clean environment, increased mobility and greater equity among Portlanders.

As the world shifts to investing in clean energy and healthier communities, cities around the world are delivering results. Portland is a leader in this effort, and we stand ready to do more. That was the message Mayor Charlie Hales and BPS sustainability manager, Michael Armstrong, took to Paris last month when they joined leaders from more than 500 cities to urge strong international action on climate change.

The global agreement that emerged from the Paris talks -- to pursue efforts to limit the increase in global temperatures to 1.5 degrees Celsius (2.7 degrees Fahrenheit) -- demonstrates an unprecedented level of international cooperation. But by necessity, it leaves much of the hard work for subsequent action to nations, states, cities the private sector and local residents. For the first time, world leaders, who signed the climate agreement, also recognized the central role of local initiatives, if we are to be successful. The agreement is international, but much of the action will be local.

With just a handful of other U.S. cities, Portland has a very encouraging record of accomplishment reducing carbon emissions. Since 1990, local emissions have declined 35 percent per person, even while  adding more than 75,000 jobs. Also since 1990, the population of Multnomah County has increased by more than 182,000 residents, yet total emissions are down 14 percent. Clearly we are doing more with less energy.  We are more efficient, we are saving money, and we are using more renewable energy sources. This is good news and Portland is making progress, but we have a long way to go: Portland’s goal, along with other leading cities, is to reduce 1990 level carbon emissions by 80 percent by 2050.

That will require much more from all of us — from the city, the private sector, non-profits, academic institutions, faith organizations and individuals. It is important than we understand that these reductions are not necessarily hardships.  A new low-carbon economy, which relies on less energy and fewer fossil fuels, presents us with an enormous opportunity to be more efficient, create jobs, and build a healthier and more vibrant community for all Portlanders, addressing equity each step of the way. As French President Hollande said in speaking to the group of mayors in Paris, “You can't separate climate action from the struggle against inequality.”

The role and value of cities had unprecedented visibility in Paris. Alongside mayors from Rio de Janeiro, Sydney, London, Los Angeles, Vancouver (BC), and Copenhagen, Mayor Hales was a featured speaker and shared Portland’s experience in creating employment and a livable community, while reducing carbon emissions.

“When you listen to most national leaders talk about this issue, you hear a language that’s really about the allocation of burden,” Hales said. “But Mayors and cities are not looking at it that way, because of our experience. Portland is prospering because we are green, because we’ve reduced our carbon footprint even while our economy has grown. We see climate action as an economic strategy for success, not a burden that we have to shoulder.”

Paris Mayor Anne Hidalgo was also compelling, declaring early in the negotiations, “I have this to say to the negotiators: We cities will be with you, but we need you to be with us, too.” Cities are leading and will continue to do so, but success requires a strong partnership with state and national governments.

Days after returning to Portland, Mayor Hales hosted the mayors of San Francisco, Seattle, Los Angeles and Eugene for two days of discussions focused on climate change, housing affordability, and homelessness. On the surface, these topics seem mostly unrelated.  However, the mayors together recognized their interconnections, and they emphasized the words of Pope Francis earlier this year: “Environmental issues are social issues.”

Together with other West Coast cities, Portland is committed to meeting the linked challenges of environmental quality, housing affordability, climate change, and building a city where families and businesses can thrive today and in the future.

This commitment, however, will not see results without the involvement of a determined community of advocates and organizations. I am profoundly grateful for your involvement, the individual and business actions you have taken, and the many hours you have spent at public hearings, testifying, writing letters or volunteering on committees.  Thank you – your efforts make a difference.

All the best for an abundant and resilient 2016.

Home deconstruction grants are still available

When a house must come down, deconstruction is a preferred alternative. Now, there’s help to save valuable building materials for reuse.

Grants are available now from the City of Portland to help promote home deconstruction, to build capacity within the industry and to encourage efficiencies and innovation.

Grant program features easy-to-use online application

  • Funds are available for a limited time.
  • Maximum grant awards: $2,500 for full deconstruction; $500 for partial projects.
  • Applications will be reviewed and selected weekly.
  • Applications are restricted to projects involving the full removal of a house or duplex within the Portland city limits.
  • Find the online application at

Why deconstruction?

Deconstruction helps achieve the policies and actions related to the current efforts of the Climate Action Plan Update and the Comprehensive Plan Update.

  • Salvaging reusable material supports the local economy by supporting six to eight jobs for every one job associated with traditional mechanized demolition and creates viable local enterprises.
  • Deconstruction offers an affordable option for residents and businesses to acquire quality used building materials.
  • Deconstruction offers greater carbon benefits by preserving the embodied energy of existing building materials and avoiding the creation of greenhouse gasses associated with adding waste materials to the landfill.

For more information on deconstruction or to apply for a grant, please visit or contact Shawn Wood at or 503-823-5468
