More Elbow Grease, Less Rocket Science
December 8, 2013

City sustainability directors face challenges in moving from bold greenhouse gas (GHG) emissions reduction goals to achieving actual GHG reduction. Examples of strategies and tactics in energy efficiency, distributed renewable energy, and low-carbon transportation are available to emulate but creating a locally tailored package of actions that “adds up” to meet a long-term reduction goal requires some elbow grease.

Doing the carbon math for cities is not just an issue for energy nerds or urban policy wonks. Cities emit 70 percent of the world’s climate pollution, and they have the potential to make a huge difference in whether we as a global society can achieve the scale of reductions necessary to avoid the most catastrophic effects of climate change.

Many city officials have set a high bar for GHG reduction. A range of cities and counties across the United States have adopted GHG reduction goals that up the ante from prior city commitments to the Kyoto Protocol.

Leading cities and counties have set goals of 80 percent reduction below current levels by the year 2050 (“80x2050”), on par with what climate scientists conclude is necessary to stabilize the climate. Still others have set an ambitious goal of carbon neutrality by 2050.

But many of these goals originated as political statements that lacked clear roadmaps for achievement. While the Recovery Act Energy Efficiency Conservation Block Grant (EECBG) program and the Environmental Protection Agency’s Climate Showcase Communities program helped cities to deepen their planning and project implementation, strategies that actually add up to 80x2050 reduction are still far from commonplace.

As we have helped small- and medium-sized cities in the U.S. Northwest to do this work, the New Energy Cities team has explored valuable efforts of a variety of change agents and thought leaders across the country:

  • California’s Institute for Local Government maintains a list of best practices for city-led GHG reduction.
  • Santa Monica, CA’s 15x15 Climate Action Plan is valuable for its simplicity as “a short-term, action-oriented document that identifies 15 measures… and associated actions [that] will serve as a checklist to be completed by the end of 2015 and, if implemented, are anticipated to result in GHG emissions reductions sufficient to meet the 2015 target.”
  • In addition to the FortZED project, Fort Collins, CO has estimated how it would get to 80x2050 based on a combination of community engagement and technical analysis by the Rocky Mountain Institute, much like a collaboration between the City of Issaquah, WA, New Energy Cities, and Ecotope in Washington’s Puget Sound region.
  • ICLEI-Local Governments for Sustainability developed tools for California cities to estimate the GHG reduction potential of different actions, although cities outside the Golden State will have to wait until early 2014 for the national version of ICLEI's tool.

We have conducted our own analysis, in spreadsheets, mind maps, and lengthy Word documents, to help our partner cities wrap their minds around what we collectively called the “known universe of city GHG reduction tactics” and their order-of-magnitude GHG reduction potential.

Until recently, we found no single compendium of the most GHG-effective practices adding up to a broader goal. Practically, GHG reduction potential of any given action depends on a specific community’s energy sources and use patterns. In other words, a GHG reduction checklist is not transferable from Burlington, VT to Bellingham, WA.

But we recently discovered a new resource that we feel breaks through this wall. Based on a scan of leading thinking and action on urban GHG reduction, and an enormous amount of research, the Innovation Network for Communities and O-H Community Partners have compiled a thought-provoking series of materials on what cities are doing to move toward carbon neutrality, as well as what they should do.

The result is “a set of ‘roadmaps’ to help communities achieve an 80 percent reduction in carbon emissions by 2050,” through actions in the building and transportation sectors, waste, energy generation, and infrastructure.

To get to 80x2050, the report authors say, cities should pursue a combination of multi-decade pathways, including:

  • Achieve net zero emissions in 100 percent of new buildings by 2030
  • Achieve 30-50 percent reductions in 100 percent of existing buildings
  • Achieve 3 percent or more annual improvements in energy efficiency of industrial processes, and reduce building energy use by at least 15 percent
  • Achieve annual net decreases in total vehicle miles traveled (VMT)
  • Decrease emissions per vehicle mile traveled (VMT) by 50-75 percent
  • Eliminate 100 percent of solid waste disposed of via landfill or incinerator
  • Achieve 80-90 percent de-carbonization of electricity and heating supply
  • Implement efficient land-use planning
  • Design municipal infrastructure for low-carbon performance

An individual city still has to do the math to determine which targets to set and what initiatives are necessary to achieve them, depending on the local energy profile, opportunities, and challenges. But armed with this gold standard of what’s necessary, staff can get more quickly to the work of what’s possible—creating and implementing meaningful, practical plans that are on par with the reduction challenge.

Perhaps the most important lesson of all: getting to 80x2050 does involve carbon math, but the more we can simplify the spreadsheets, the better.  For busy city officials, GHG reduction should be more about elbow grease and less about rocket science.

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.
