The city of Portland, Oregon, prides itself on being ahead of the curve. In 1993, it became the first U.S. city to adopt a climate action plan, which now calls for cutting carbon emissions by 50% by 2030, and to achieve net zero carbon emissions by 2050. Portland also has long been a leader in progressive urban planning strategies, and since 2006 has been a member of C40, an international network of cities seeking innovative ways to reduce emissions.
That’s why in 2013, as the city’s planners began to develop the 2015 update to the climate plan, they started working with a new model to calculate the city’s carbon emissions profile. Using the Stockholm Environment Institute’s model, the city could enumerate the emissions of the life cycle of 536 different products and commodities used in the Portland metropolitan area—everything from raw materials like timber and food crops, to manufactured items like office furniture and chocolate.
It made for an unpleasant surprise.
“We actually all of a sudden had all this data about the impact of consumption,” says Kyle Diesner, Climate Action Program coordinator in the city’s Bureau of Planning and Sustainability. “The global carbon emissions that came from our model showed that the global emissions were double the emissions that we were reporting locally. And the bulk of those emissions, about 60%, come from the production of goods, food, materials, and much of that [is] happening outside of our city.”
That meant carbon reduction policies based on previous emissions estimates had likely grossly underestimated how much carbon they needed to offset. Recalculating Portland’s carbon footprint meant taking into account the impacts of the city’s economy on other regions around the world that are in different parts of the supply chain for those hundreds of commodities.
“If we want to reach our carbon reduction goals, there’s really this elephant in the room: this huge footprint from our consumption, [which includes] emissions that have been outsourced to other countries that aren’t a part of our emissions inventory,” Diesner says.
To obtain a holistic emissions inventory, the carbon footprint for each product would need to be counted starting from its site of manufacture, and include the emissions attributable to its transportation to and storage in Portland, not just those resulting from the product’s active use.
But a wholesale reimagining of a city’s decades-long climate planning can’t be done in a vacuum. So when Portland had an opportunity to join a new pilot project that sought to make urban governance and decision-making more sustainable, leadership jumped at the chance.
Cities Initiative. The Initiative is a collaboration between C40, the Amsterdam-based Circle Economy, which seeks to create zero-waste urban economies that support their residents, and the Doughnut Economics Action Lab, an organization mostly comprising volunteers working to implement systemic, society-wide economic change.
That last organization is important, because “doughnut economics” is a theory that incorporates social and environmental well-being into a holistic view of an economy. First developed by Kate Raworth, and the subject of her 2017 book, Doughnut Economics: 7 Ways to Think Like a 21st Century Economist, the theory has caught the attention of teachers, businesses, community groups, and city planners like Diesner.
At its most basic level, doughnut economics is a way of describing an economic system that extends beyond strictly financial measures, like gross domestic product, to include environmental sustainability and healthy, thriving communities.
Diesner and others in Portland’s administration were familiar with the concepts in Raworth’s work, and were looking for ways to downscale and apply them at the municipal level, he says. The Thriving Cities Initiative’s model—and the expertise and resources it provided—dovetailed with Portland’s existing momentum in tracking and reducing emissions that accounted for spending by government, businesses, and households. The model also pointed to ways to address the city’s social issues, including more than 4,000 people in the metro area without stable housing.
The hope was that doughnut economics could help tackle those social issues. “How do we lift up communities that have been left behind?” Diesner asks.
