Lagos bans single-use plastics

By /

On July 1, 2025, Lagos introduced a ban on single-use plastics like Styrofoam plates, straws, and cutlery. The city—home to 20 million people—has long battled severe plastic pollution, with clogged waterways worsening floods and harming health. The ban is already driving grassroots recycling, sparking innovation in sustainable packaging, and raising public awareness about waste reduction. If supported by stronger enforcement, better waste systems, and affordable alternatives, this move could slash hundreds of thousands of tons of plastic waste annually—positioning Lagos as a model for African cities aiming to protect their environment and build a cleaner, more resilient future.

Flint, Michigan at last replaces corroded pipes after lead crisis

By /

Flint’s lead crisis began in 2014, when the city began drawing water sourced from the Flint River instead of from Lake Huron. The river water was more corrosive than the lake water, and the city failed to take the additional steps needed to prevent lead from leaching into drinking water. In 2017, a federal court ordered the city to replace all lead pipes within three years. Eight years later is the project finally complete. State officials told a federal court this week that the city has excavated more than 28,000 properties in search of lead water lines and replaced nearly 11,000 pipes.

Spokane passes LGBTQ+ rights ordinance to protect trans folks from the federal government

By /

Council members voted 5-2 to implement the ordinance, which updates the Washington State city’s human rights code to define gender-affirming care and ensure equal protections for LGBTQ+ people. The policy “prohibits the city from collecting or disseminating information about anyone’s sex assigned at birth, unless it’s related to a criminal investigation.” The ordinance also requires city-provided healthcare to cover gender-affirming care. Council members celebrated the city living up to its motto: “In Spokane, we all belong.”

Paris residents vote to make 500 more streets pedestrian

By /

Parisians voted to pedestrianize a further 500 of the city’s streets, giving fresh momentum to efforts by the French capital’s left-leaning town hall to curb car usage and improve air quality. The referendum will eliminate 10,000 more parking spots in Paris, adding to the 10,000 removed since 2020. The 500 additional streets to be pedestrianized will bring the total number of these so-called “green lungs” to nearly 700, just over one-tenth of the capital’s streets.

New Delhi transforms degraded lands into biodiversity parks

By /

New Delhi, India’s capital city, struggles with numerous environmental challenges, including extremely poor air quality and heat waves. In response, since 2004, the city has created seven large “biodiversity parks” on previously degraded land. The Aravalli Biodiversity Park, a 692-acre park located near an upscale neighborhood, is now a thriving forest of native plants. The Neela Hauz Biodiversity Park is home to a lake that was once a dumping ground for untreated sewage. All seven parks were restored by the Delhi Development Authority and the University of Delhi and together span 2,026 acres.

Minneapolis to become first city in North America to own and operate biochar facility

By /

Biochar is a specialized charcoal created by heating wood waste to 700 degrees in a low-oxygen environment. The Minneapolis biochar facility will have the capacity to annually: process over 3,000 tons of wood waste, produce over 500 tons of biochar, and remove nearly 3,700 tons of carbon dioxide (the equivalent of taking over 789 cars off the road). Construction is expected to begin this spring with biochar production beginning in the summer or early fall.

Nearly half of new E.U. city buses were zero-emission in 2024

By /

49% of all new E.U. city buses were zero-emission in 2024, making city buses one of the early success stories of the European Green Deal. This growth is due to the faster-than-expected uptake in fuel cell buses, making up 3% of new E.U. city buses in 2024. Battery-electric, however, remains by far the dominant powertrain, with a 46% share. This success is due to both the new European regulation last year sending a clear market signal that the days of diesel buses are numbered and city-level policies such as zero-emission zones and fleet targets.

Abu Dhabi to build world’s largest solar energy project

By /

Abu Dhabi will soon be home to a 5.2-GW solar farm, enough to power 750,000 homes and become the world’s new largest-ever solar energy project. The project will cost US$6 billion, and is set to be commissioned in 2027. It will consist of around 10 million solar panels across 20 square miles, more than 10,000 football fields. The new project in Abu Dhabi not only earns the United Arab Emirates major bragging rights, but also gets it closer to its Net Zero by 2050 target.
