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鈥檚 why in 2013, as the city鈥檚 planners began to develop the 2015 update to the climate plan, they started working with a new model to calculate the city鈥檚 carbon emissions profile. Using the Stockholm Environment Institute鈥檚 model, the city could enumerate the emissions of the life cycle of 536 different products and commodities used in the Portland metropolitan area鈥攅verything from raw materials like timber and food crops, to manufactured items like office furniture and chocolate.

It made for an unpleasant surprise.

鈥淲e actually all of a sudden had all this data about the impact of consumption,鈥� says Kyle Diesner, Climate Action Program coordinator in the city鈥檚 Bureau of Planning and Sustainability. 鈥淭he 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.鈥�

That meant carbon reduction policies based on previous emissions estimates had likely grossly underestimated how much carbon they needed to offset. Recalculating Portland鈥檚 carbon footprint meant taking into account the impacts of the city鈥檚 economy on other regions around the world that are in different parts of the supply chain for those hundreds of commodities.

鈥淚f we want to reach our carbon reduction goals, there鈥檚 really this elephant in the room: this huge footprint from our consumption, [which includes] emissions that have been outsourced to other countries that aren鈥檛 a part of our emissions inventory,鈥� 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鈥檚 active use. 

But a wholesale reimagining of a city鈥檚 decades-long climate planning can鈥檛 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.  

Portland joined Philadelphia and Amsterdam as the first cities to pilot the Thriving 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 鈥渄oughnut economics鈥� 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鈥檚 administration were familiar with the concepts in Raworth鈥檚 work, and were looking for ways to downscale and apply them at the municipal level, he says. The Thriving Cities Initiative鈥檚 model鈥攁nd the expertise and resources it provided鈥攄ovetailed with Portland鈥檚 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鈥檚 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. 鈥淗ow do we lift up communities that have been left behind?鈥� Diesner asks.

A Visual Aid for Rethinking Economics

Kate Raworth started on the road to what would become her signature theory while an economics student at Oxford University in the early 1990s. She realized that the prevailing neoliberal economics in the capitalist industrialized world had a major flaw: The focus on measuring a nation鈥檚 strength solely on financial measures such as GDP did not account for the myriad other issues confronting modern society, especially environmental damage.

鈥淵ou couldn鈥檛 study economics of the environment,鈥� Raworth says. 鈥淭here was no course.鈥�

Through her work for the government of Zanzibar, in Tanzania, and on the United Nations Human Development Report, Raworth was exposed to a wider spectrum of economic thinking. She read Robert Chambers鈥� work on rural poverty, Herman Daly鈥檚 鈥渇ull world鈥� model of a finite biosphere, and Hazel Henderson鈥檚 visualization of a more holistic economy as a layer cake, in which GDP only encompasses the top half of the cake, and the market economy is just the topmost layer of icing.

Raworth was inspired by Henderson鈥檚 sheer gumption in visualizing the economy with something as seemingly frivolous as a dessert. She realized that being able to visualize ideas helped them to gain traction in the public imagination.

Then the global economy collapsed in 2008, and capitalist economies around the world plunged into the Great Recession. As talk in the halls of power turned toward restoring the existing world economy, Raworth could see that renewing a commitment to neoliberal economics was a recipe for future disaster.

Raworth saw an opportunity to rewrite the global economic agenda to reflect the entire human and environmental experience.

鈥淚 thought, 鈥楬ang on鈥斅�颅颅颅颅if this is a moment when economics is going to get rewritten, I鈥檓 not going to sit by and watch it only written from the point of view of finance,鈥欌�� she says.

Thus emerged the visual idea of a doughnut: two concentric rings, the outer symbolizing the world鈥檚 ecological ceiling (beyond which lies environmental destruction and climate change), the inner symbolizing the social foundation (inside which is homelessness, hunger, and poverty). The space between the two rings鈥攖he 鈥渟ubstance鈥� of the doughnut鈥攚as the 鈥渟afe and just place for humanity.鈥�

The world already was overshooting the ecological ceiling and falling short of the societal foundation in many places. 

The neoliberal narrative has long claimed we would 鈥済row our way out of inequality,鈥� despite evidence that growth tends to exacerbate existing problems. So how could a re-envisioned economy be put into action? 

For Raworth, implementing the ideas right away was key. 鈥淚 鈥� firmly believe 21st century economics is going to be practiced first, theorized later,鈥� she says.

The Dutch Example

Amsterdam was one of the first cities out of the gate. The city had already passed legislation in 2019 to have zero fossil-fuel vehicles in the city by 2030, and by 2050, to have a completely circular economy, meaning the city will avoid waste altogether by re-using, refurbishing, and recycling raw materials.

The Dutch capital鈥檚 plan for the next 30 years specifically embraces doughnut economics as its guiding strategy.

鈥淚t was a visualization of a paradigm that they were clearly moving toward already,鈥� Raworth says.

The Thriving Cities Initiative produced the Amsterdam City Doughnut report, a holistic look at the city鈥檚 local and global impacts on people and the environment. It outlines goals as broad as making Amsterdam a 鈥渃ity for people, plants, and animals,鈥� and as specific as 鈥渞educe the city鈥檚 total CO2 emissions to 55% below 1990 levels by 2030, and to 95% below by 2050.鈥�

The plan goes beyond just removing combustion-powered vehicles from city streets and aggressive recycling. 

鈥淲e ship cocoa from Ghana all the way to the Port of Amsterdam,鈥� says Jennifer Drouin, the community manager of the Amsterdam Doughnut Coalition, via email. 鈥淏y doing that we not only contribute to a large amount of CO2 emissions (and therefore exceed the ecological boundaries) but are also indirectly contributing to child labor in West Africa.鈥�

At the same time, the city is becoming unaffordable to live in, driven by foreign investors and Airbnb owners renting out properties for high rates before the COVID-19 pandemic hit. 鈥淟ocals literally can no longer afford living in the city,鈥� Drouin says. 

Stricter regulations have since been imposed on Airbnb and similar services by the city, Drouin says, and even hotels are rethinking their business models and have offered discounted rates for local residents displaced by the pandemic. The cocoa problem presents different challenges鈥攃ocoa is a tropical crop鈥攂ut at least city officials are more aware of the problem now, a crucial first step.

鈥淚 am convinced that they will try and change the way they are importing, and also will think about how they can positively contribute to the labor rights in Ghana,鈥� Drouin says.  

Adopting an ambitious re-envisioning of the city鈥檚 economy doesn鈥檛 come easily. Organizers convened a multi-day series of workshops in 2019 that included municipal, community, and business leaders. The end result was a city 鈥減ortrait鈥� that considers the city through four lenses: what it would mean for the city鈥檚 people to thrive, how the city can thrive within ecological limits, how the city impacts the health of the entire planet, and how the city affects the well-being of people around the world. 

In the end, we need a co-created dream, something we can look forward to, something where no one is left behind, neither the people nor the planet.

Amsterdam鈥檚 model is 鈥渓earning by doing. They鈥檙e very keen to experiment,鈥� says Ilektra Kouloumpi, the senior cities strategist for Circle Economy, which has been working with the city for several years. 

鈥淭o create this process of bringing the doughnut to the city, to take it from a conceptual, theoretical model into practice,鈥� Kouloumpi says, 鈥渋t makes it turn into a tool for decision-making and for design, and that happens a lot in a participatory format.鈥�

The doughnut workshops in Amsterdam identified several areas of focus, she says, including in the food production chain: bringing sources of production closer to the city, thereby reducing emissions from shipping, but also fostering stronger connections between producers and consumers, and creating more awareness among residents of their relationship to their food. 

The workshop attendees also proposed new criteria for undertaking new construction and refurbishing old buildings to maximize the use of recycled materials, Kouloumpi says. But the criteria also have to ensure there are 鈥渆nough of those new buildings available for different incomes, so that they can provide housing for all levels of income.鈥�

Different Cities, Different Priorities

If Amsterdam was a city already primed to re-make its economy, Philadelphia is still in the early stages of the process.

The city has an action plan to be a zero-waste city by 2035, and was a charter member of C40, says Christine Knapp, the director of Philadelphia鈥檚 Office of Sustainability. 

A daylong Thriving Cities Initiative workshop in September 2019 brought together city staff from several departments, community leaders and organizations, and businesses to create a city portrait.

鈥淭he goal was to hold a second workshop to go deeper, expanding and creating an action plan,鈥� Knapp says.

Then the COVID-19 pandemic broke out, and the city shut down. In June 2020, the city council cut its budget by $222.4 million, and 450 staff were laid off, including the person leading the city鈥檚 dedicated zero-waste cabinet.

鈥淲e鈥檙e using COVID as a proxy for a climate disrupting event, like a hurricane.鈥� That鈥檚 allowed the city to take a fresh look at legacy problems, such as food insecurity.

Philadelphia is also starting from a different point: It鈥檚 the poorest large city in the United States, Knapp says, with a majority non-White population, and poor air quality leading to high rates of asthma, especially among children and people of color.

鈥淧hilly is a deindustrialized city that鈥檚 been hollowed out,鈥� Raworth says. The stark racial injustice was apparent to her during the doughnut workshop. 

That put even more emphasis on the need to ensure that an economic recovery also will be a just one. 鈥淲e can鈥檛 just wait until we鈥檙e back to normal and [then say], 鈥楲et鈥檚 transform,鈥欌�� Raworth says. 鈥淭hat never happens.鈥�

Instead, a catalyst must help accelerate change. In 2020, that catalyst was a tragic one: The pandemic ravaged many countries and led to more than 2 million deaths in one year. In the U.S., the stock market and the wealthy continued to see their net worths increase while millions were thrown out of work and are still at risk of losing their homes.

鈥淐OVID-19 recovery needs to be a green and just recovery,鈥� Knapp says. 鈥淲e鈥檙e using COVID as a proxy for a climate disrupting event, like a hurricane.鈥�

That鈥檚 allowed the city to take a fresh look at legacy problems, such as food insecurity. It was difficult for people to get fresh fruits and vegetables in the early months of the pandemic, Knapp says.

鈥淲e get a lot of school meals packaged and sent to us from a location in Brooklyn,鈥� she says. 鈥淚f we took 10% of those meals and made them locally, we鈥檇 have to purchase more food from local farms, hire more people.鈥�

And because the local food system is run largely by people of color, who also are underpaid, that shift in resources could have wider ripple effects. But all those shifts will cost money.

Philadelphia鈥檚 poverty and unemployment rates were decreasing before the pandemic, but those gains may now have been wiped out, and the city will continue to suffer without more and continuing support from Congress.

鈥淯nless we have lots of federal support, which we hope will be coming, it will be hard to do anything new or untested,鈥� Knapp says.

Moving Forward

The pandemic also forced Portland to scale back its Thriving Cities program. 鈥淲e were going to be doing community engagement through these Thriving City workshops, to build community awareness about our work on sustainable consumption, but more importantly, to co-develop solutions together with the public for how we choose a low-carbon future for everyone, where all Portlanders can thrive,鈥� Diesner says. 

Those workshops were canceled, he adds, and a five-year program that could have formed the basis for city council action was scaled back to a two-year in-house plan that the city鈥檚 Bureau of Planning and Sustainability could follow on its own. Still, some existing programs already were in line with the goals of the Thriving Cities Initiative, Diesner says.

The River Speaks

Portland鈥檚 1,720-foot-long 鈥淭ilikum Crossing, Bridge of the People鈥� connects two halves of the city. Built in 2016, it became the nation鈥檚 longest bridge off-limits to automobiles, with dedicated lanes for pedestrians, bicyclists, buses, and light rail.

And the bridge’s designers took environmental congruity a step further. Monitors from the U.S. Geological Survey and the National Oceanic and Atmospheric Administration feed data from the Willamette River to the bridge鈥檚 lighting system, allowing the river to communicate. The temperature of the river controls the color of the lights. The warmer the river, the warmer the colors鈥攐range and yellow. Cooler temperatures display as greens and blues. The tide controls the lights鈥� movement, and the speed of the river controls how quickly the colors change. The river鈥檚 height, which changes with the seasons, affects the contrast in the lights.

In Amsterdam, the Doughnut Coalition and the city government are already looking toward next steps.

Part of the challenge is going to be to get businesses to become more socially focused, Drouin says. 鈥淲e cannot transform the system when businesses are still dependent on their shareholders鈥� investment, [which is] mainly money-driven instead of purpose-driven.鈥�

Building public awareness will also be a challenge, she says. 鈥淗ow can we become a doughnut city when my neighbor hasn鈥檛 heard of it or doesn鈥檛 understand why it is relevant for her? Why should people care about a new economic model when they are struggling to pay their rent or get their kids to school?鈥�

鈥淚n the end, we need a co-created dream,鈥� Drouin says, 鈥渟omething we can look forward to, something where no one is left behind, neither the people nor the planet.鈥�

That鈥檚 what has drawn so many people to the doughnut model in the first place. 鈥淭he model is powerful because it鈥檚 simple and speaks to everyone,鈥� Kouloumpi says. 鈥淭he problem is how to bring those people together, this very mixed group, that鈥檚 not used to being together.鈥�

Raworth says a lot of that comes down to communication, changing minds one at a time. 鈥淚t seems like it could take forever to change paradigms,鈥� Raworth says. 鈥淏ut in an individual, it can happen in a blink of an eye, the scales falling away.鈥�
