20 years later, a small Maine town finally found a way to solve its 27,000-ton carpet dump problem

An Albuquerque program pays panhandlers to clean up city trash—and gets them needed help, pairing city services with a jobs program.

In Philadelphia, the City Bright initiative is working to pay individuals experiencing homelessness to help clean up the streets in city neighborhoods. While it might not pay much and is not a silver bullet solution, incentives like recommendations and the small amount of pay can help - and are part of a larger trend around the country.

Public art adds value to communities that have experienced decline in recent decades. In towns like Mansfield and Marietta, Ohio, public art plays a positive role. Murals created by groups like Mansfield Murals Inc., or by other local artists, enhance public buildings and offer a way for residents to connect and express their history. In Marietta, the Marietta Community Foundation funds the city’s Public Arts Committee.

Amager Bakke is a powerplant in Copenhagen that is designed to get residents of the city engaged in a conversation about where waste goes, all while burning up to 400,000 tons of waste a year, powering 60,000 homes, and heating 160,000 homes. In 2013 the local plant was redesigned to burn the city's waste and encourage interaction by building a ski slope atop the plant, a hiking trail, and an elevator that introduces education about waste management. Amager Bakke is still new and experimental, so its long-term success is still unclear, and it is not completely emission-free yet.

Kibra Green, a grassroots organization in Kenya, mobilizes the young people in the community to clean up their neighborhood. At times, the group has as many as 500 participants for a community-wide clean up. Yet, a lack of steady funding and socioeconomic barriers for volunteers to regularly contribute to the group has made it difficult to scale the organization.

To mark the 100th anniversary of the Tulsa Race Massacre, in which a white mob killed hundreds of Black residents and destroyed the thriving neighborhood of Greenwood, the Centennial Commission supported a number of initiatives to learn from the past and build a better future. At the base of an ancient elm tree that witnessed the massacre, Up With Trees distributed 100 elm seedlings to children to plant around Tulsa. The commission convinced state education officials to develop a new curriculum on the massacre for K-12 students.

In 2020, a devastating explosion in Beirut that came from a warehouse released 800,000 and one million tons of construction and demolition waste and 20,000 tons of shattered glass into the city. The waste was being thrown into landfills. However, landfills are notoriously bad for the environment. Out of that rubble an idea was created; disposing waste sustainably. Rubble Mountains was created specifically to do this. They've been able to restore four quarries, use materials to create public amenities, and diverting up to 50 tons of demolition waste from landfills.

Toni Griffin has gained recognition for spreading the concept of “just cities,” an approach to urban planning that involves values, justice, and equity as priorities in any project. Now director of the Just City Lab at Harvard’s Graduate School of Design, Griffin is teaching about the concepts of just cities and implementing them into projects, as well. Most recently, her design won a competition in St. Louis that will use green space to create more racially inclusive spaces in the city.

The voluntary carbon market allows small-scale landowners to receive credits for reducing climate-changing emissions, which they can sell to corporations to offset their emissions. The carbon market has provided small landowners with other options to make money besides logging.
