Beaverton, Oregon does carbon math
December 23, 2013

The City of Beaverton, Oregon is already known as a clean energy pioneer, hailed as a Natural Resources Defense Council “Smarter City” energy leader, a US Department of Energy Better Buildings partner, and a 2012 US Environmental Protection Agency Green Power Leadership Award winner.

When the opportunity recently arose to set a long-term community climate action goal, city sustainability officials wanted to do their homework. So they called the New Energy Cities team to help them figure out what it would take to make deep cuts in climate pollution community-wide.

After reviewing various possible goals, Beaverton's sustainability director Cindy Dolezel focused on an 80 percent reduction below current levels by 2050, with a near-term emphasis on 40 percent reduction by 2030.

The “80x2050” goal aligns well with targets set by the State of Oregon, as well as the Climate Smart Communities Scenario Project underway at Metro, the Portland-area regional government that serves Beaverton and other neighboring cities. It would also keep pace with leading cities nationwide. Dolezel asked the New Energy Cities team to analyze what it would mean to achieve these goals.

To start, we created a community-wide Energy Map for the base year of 2012, depicting the community’s sources and uses of energy and greenhouse gas (GHG) emissions, based on utility and transportation data. The Energy Map graphic has become a standard element of New Energy Cities’ work with cities, as it shows a community’s complicated energy system on a single page and in a simple format, and mayors tend to love it.


As a snapshot of the community’s energy system in a single year, the Energy Map was just the first step. For Beaverton to understand how to achieve an ambitious 80x2050 goal would require looking out several decades, for which the New Energy Cities team developed a Carbon Wedge analysis.

Based loosely on Princeton University’s Carbon Mitigation Initiative, the New Energy Cities Carbon Wedge graphic depicts the scale of community-led actions necessary relative to emissions growth, after accounting for the reduction impact of existing laws.

We created our first Carbon Wedge graphics for the City of Issaquah, WA in 2012, with a step-by-step methodology that served as the basis for our work in Beaverton:

  1. Identifying potential population growth between the base and goal years, and translating that into approximate GHG emissions growth in the absence of action.
  2. Estimating GHG reduction potential associated with important existing laws outside of the city’s control. In any given city, these might include the federal Corporate Average Fuel Economy standard, a state renewable portfolio standard, a state clean fuel standard, and provisions governing a state energy code, as relevant.
  3. Calculating approximate GHG reduction potential associated with different scenarios of community action.

From the start, Beaverton officials were clear that they wanted the Carbon Wedge research to reflect the impacts of existing and proposed state laws—including Oregon’s renewable portfolio standard, which mandates that utilities source at least 25 percent of total fuel mix from renewable energy by 2025, and the state’s Clean Fuel Program, which would require a 10 percent reduction of fuel carbon intensity from 2010 levels by 2025, if its current 2015 sunset were removed.

We found that these laws would collectively only “stabilize” the community’s climate pollution to its 2012 level, so to paint a picture of how Beaverton might close the remaining emissions gap, we then estimated the reduction potential of specific targets in three areas:

  • Meeting Metro’s Climate Smart Communities per capita target for transportation GHG emissions by 2035
  • Achieving a 25% reduction in energy use from existing buildings community-wide by 2030
  • Achieving 40% non-hydropower renewable energy use in electricity and heating community-wide by 2030

In Beaverton’s case, one political advantage of these targets is clear: they align with and support Oregon Governor Kitzhaber’s Ten-Year Energy Action Plan, which focuses on transportation, energy efficiency, and renewable energy.  They are also targets grounded in substance, based on national best practices identified in “The Road to 2050,” an excellent publication from Innovation Network for Communities and O-H Community Partners that distilled the cream of the crop in climate plans from around the US.

Above all, the resulting Energy Map and Carbon Wedge graphics are intended as early communications tools to frame discussions between key players in creating a clean energy future:

  • Communities and local government officials who want to achieve deep cuts in climate pollution
  • Utilities that hold the keys to the energy kingdom, including energy generation assets, sources of program funding, and deep technical expertise
  • Chambers of commerce and business leaders who place a high value on data-driven strategic planning, and who are customers and therefore key drivers of utility business decisions

To be clear, the Carbon Wedge graphics set the frame for initial conversations, and they do not define the strategies and tactics that would be crucial in an implementation plan—an essential step that will be the real barometer of progress.

But several early conclusions are evident. First, existing laws are important drivers of reduction, but they alone will not achieve the goal. Second, state, regional, and local levers of change are all essential to meet deep reduction goals for 2050, and especially the more practical interim goal year of 2030. Last but not least, the city will need to implement new actions on its own and in partnership with other cities, regional government agencies, and most definitely its energy utility.

That, driven by the political commitment and staff dedication that is characteristic of Beaverton, is what it will take.

Elizabeth served Climate Solutions as program manager for the New Energy Cities program, working with cities to help them meet their carbon reduction goals through innovative programs and policies. She most recently authored The Urban Clean Energy Revolution, a detailed compendium of urban climate solutions worldwide (also published in segments as the Low-Carbon Cities blog series), and Breaking Down Barriers to Deep Energy Efficiency in King County, a briefing paper on how to overcome obstacles to deep home energy efficiency. She also co-authored Powering the New Energy Future from the Ground Up, a July 2012 report on small and medium-sized cities around the U.S. that are demonstrating leadership in local clean energy innovation.

Elizabeth knows and loves local government. As lead author of the World Bank’s 2011 climate change adaptation guide for cities in developing countries, co-author of King County’s 2007 adaptation guidebook with ICLEI and the University of Washington, climate change aide to former King County Executive Ron Sims, and project manager of the first King County Climate Plan in 2007, Elizabeth brings a deep and wide background in community climate planning to the New Energy Cities team.

The program’s focus on "carbon math" also bears Elizabeth’s signature. She first found religion in Excel spreadsheets as the Recovery Act performance and accountability lead for the U.S. Department of Housing and Urban Development, overseeing the results of $13.6 billion in grants to cities and communities around the U.S.  Today her data-driven approach is most obvious in New Energy Cities’ energy maps and carbon wedge graphics.

Outside of work Elizabeth leaves ample time for gardening, biking, and movie-watching with her husband Andy. She holds a double degree in biology and Chinese language from Williams College and a master’s degree in public policy from Harvard Kennedy School.
