To Fix Climate Change, Big Cities Must Embrace Circularity

City leaders must embrace circularity, starting with systems that eliminate waste and keep materials in use through smart design, reuse and repair.

Circularity is the powerful climate solution that big cities are ignoring. 

There’s no getting around the fact that urban hubs are major contributors to climate change, and the problem is getting worse: In 2020, cities were responsible for about 72 percent of global greenhouse gas emissions, up from 62 percent in 2015.

It’s also equally clear that the current approaches alone can’t reverse the damage we’re doing to the planet. 

We should all be encouraged that London has introduced fees on high-polluting vehicles in its city center, Paris has outlawed diesel cars and New York has enacted Local Law 97 to regulate emissions from buildings. But these steps only address direct greenhouse gas emissions from buildings and transportation.

There’s more to creating and maintaining a more sustainable and resilient city than reducing emissions from direct emissions sources like heating, cooling and vehicles. In an interconnected global economy, it’s (over)consumption that’s driving emissions higher and higher worldwide. Research shows that we need to reduce indirect emissions from consumption in cities by as much as 50 percent by 2030 to have any hope of staying below the limit of 1.5 degrees Celsius established in the Paris Agreement.

This means city leaders must embrace circularity.
So what is circularity, and how can it help? Very simply, a “circular city” is one that eliminates waste and keeps materials in use for long periods of time through smart design, reuse and repair. 

Circularity is an antidote to waste and planned obsolescence. Cheap, disposable goods and wasted food cycle through our cities and quickly end up in landfills. New York City, for example, produces over 14 millions tons of trash every year, and about 75 percent of it is sent to landfills in central New York State, Pennsylvania, Virginia and South Carolina. Landfills, which are also major drivers of climate change, are disproportionately located near low-income communities. 

In addition to reducing waste and emissions, a truly circular city also brings social and economic benefits by increasing access to high quality goods, building community resilience, benefiting local businesses and creating local jobs.
And as we’ve seen with the Circular Campus initiative I’ve spearheaded at Barnard College, taking action to fix overconsumption is possible.  

Here’s how we can pull policy levers to scale up this approach to the city level: 

Accurately measure and report on indirect emissions from consumption. Too many cities focus solely on direct emissions, which isn’t enough.

Make repair and reuse services tax exempt. Every thrift store, repair shop, dry cleaner that provides alterations, and hardware store that repairs lamps is part of the circular economy. These businesses should be incentivized to continue offering and expanding upon their sustainable practices.

Restructure waste collection. Pay-as-you-throw waste collection – when combined with incentives for reuse in construction – will help individuals and businesses send fewer large items to landfills and reduce waste overall.

Make composting mandatory. Providing tax breaks for buildings and organizations that recycle and compost will reduce the amount of waste that is sent to landfills.

Support circular businesses. Funding innovative circularity start-ups will help them build the reverse logistics systems needed to refine circularity initiatives that will benefit everyone. Once all the kinks have been worked out, city governments can put these systems into effect all across the country.

Circularity is a powerful tool in the fight against climate change, waste and inequity, but we’re not using it to the extent we should be: Data released in 2021, for example, show that only about 8.6 percent of the global economy is “circular.” The World Resources Institute calculates that by “doubling global circularity in the next 10 years, global greenhouse gas emissions could be reduced by 39 percent by 2032.” 

Big cities, though, are the perfect place to develop and scale circular systems, and when it comes down to it, circularity is a refreshingly simple ideology: It requires us to produce and buy only what we need, take good care of our things and repurpose them when they’re no longer of use. This ancient practice is already a familiar, but too often informal, part of our daily lives. From neighborhood swaps to compost sites to public libraries to building retrofits and preservation, circularity is all around us. Our job is to recognize, resource and scale this powerful, common sense approach to living.

Embracing this basic idea will allow our big cities to thrive in harmony with the planet.
