In São Paulo, Earth Day Begins Block by Block

São Paulo marked Earth Day 2026 by bringing thousands of people together to clean neighborhoods they call home. Residents, students, municipal workers, and environmental groups came together for a coordinated day of cleanup and community action, removing nearly 150 tons of waste from neighborhoods, parks, and public spaces. 

A City Organizes Itself

São Paulo is a massive city with a population of around 11.4 million people and is divided into 32 subprefectures. Having to coordinate a unified environmental effort across all of them is no small task, yet that is what happened this Earth Day. 

To prepare for Earth Day, São Paulo partnered with Clean Brazil Institute or Instituto Limpa Brasil as part of EARTHDAY.ORG’S Great Global Cleanup campaign. Through the Great Global Cleanup campaign, EARTHDAY.ORG supported local partnerships that helped train community leaders, mobilize volunteers, and connect São Paulo’s cleanup to a global movement for community action. 

A mutirão is more than a neighborhood cleanup. It is a long-standing tradition of neighbors coming together to solve a shared problem or achieve a common goal through collective volunteer work. That tradition guided São Paulo’s Earth Day activities from start to finish.  

The preparation began on Earth Day itself. On April 22nd, community leaders gathered for training that prepared them to organize volunteers and lead cleanup efforts in their own neighborhoods. Then, on April 25, those leaders led simultaneous cleanup crews across every subprefecture in the city.

By Earth Day, those trained community leaders had mobilized more than 2,000 volunteers to participate in hands-on cleanup efforts, while residents took part in surrounding community events and awareness activities that gave the day its scale. Volunteers hauled plastics, paper, and other irregularly dumped trash from streets and squares.  

More Than a Cleanup

The goal was never to simply haul away trash. It was to show, block by block, that lasting environmental progress starts with people getting involved. By the end of the day, volunteers had removed roughly 150 tons of waste in a single coordinated effort, showing what community action can achieve.

Environmental education in local communities was a part of the effort. São Paulo’s State Environmental Education Policy describes this kind of work as a way to help students build a sense of responsibility and belonging toward parks, rivers, and public spaces around them. 

Waste picker cooperatives were also an important part of the cleanup, helping sort and recover recyclable materials while connecting a one-day event to an ongoing recycling system. The work didn’t end when Earth Day was over. Brazil recognizes waste picker cooperatives as partners in municipal waste management through its National Solid Waste Policy, and their role helped ensure that recyclable materials collected during the cleanup continued through São Paulo’s recycling system. 

Part of Something Bigger

São Paulo wasn’t the only city taking action this Earth Day. Through EARTHDAY.ORG’S Great Global Cleanup, communities in 190 countries organized cleanups throughout April 2026. These efforts show how local cleanups can bring communities together while encouraging long-term action on illegal dumping and waste management. 

A São Paulo Waste Study found that when trash isn’t managed properly it can contaminate waterways and worsen flooding, challenges that the city has been facing for years. While every community approaches cleanup differently, São Paulo showed what can happen when local leadership, residents, schools, and environmental organizations all work towards something that feels distinctly local. 

Whether it’s joining a local cleanup, organizing neighbors, or participating in EARTHDAY.ORG’s Great Global Cleanup, every effort helps build healthier communities, one block at a time. Find a cleanup near you and get involved at EARTHDAY.ORG.
