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.

Ethiopia to plant 700 million trees in one day

By /

Ethiopia has launched a record-breaking push to plant 700 million trees in a single day, part of a plan to grow 50 billion by 2026 to fight deforestation, boost livelihoods, and tackle climate change. By early morning, 14.9 million people had already planted 355 million seedlings. The nationwide effort has been championed by Prime Minister Abiy Ahmed since 2019 as a personal and national priority.

Vatican strikes solar farm deal to become the world’s first carbon-neutral state

By /

Italy has agreed to a Vatican plan to build a solar farm on 1,000 acres near Rome, aiming to make Vatican City the world’s first carbon-neutral state. The Santa Maria Galeria project will generate enough clean energy for the micronation while preserving the land’s agricultural use and minimizing environmental impact. This step marks a significant commitment by the Vatican toward sustainability and climate leadership.

New York becomes first U.S. state to require all-electric new buildings

By /

Buildings are one of New York’s biggest climate polluters, responsible for nearly a third of the state’s emissions. In 2025, the state finalized the nation’s first statewide gas ban, requiring most new buildings to run on electric systems, with larger ones following in 2029. A federal court upheld the law, clearing the way for implementation. By ending fossil fuel hookups in new construction, New York is cutting a major source of greenhouse gases, improving air quality, and creating a model for other states—pushing the country closer to a future where all buildings help solve the climate crisis, not fuel it.

World Court says countries are legally obligated to curb emissions and protect climate

By /

A landmark decision by the International Court of Justice in The Hague, Netherlands has cleared the way for countries to sue each other over climate change. Campaigners and climate lawyers have called this a “watershed legal moment” and hope the decision will pave the way for compensation from countries that have historically burned the most fossil fuels. The unprecedented case was the brainchild of a group of young law students from low-lying Pacific islands on the frontlines of climate change, who came up with the idea in 2019.

More than 90% of global new renewable energy capacity is now cheaper than fossil fuels

By /

The global switch to renewable energy has passed a “positive tipping point,” according to two United Nations reports. Solar is now 41% cheaper than fossil fuels worldwide. Not long ago, it was four times the cost. Offshore wind is now also 53% cheaper and the most affordable source of new renewable energy. Even more, costs for renewables are expected to keep dropping as technology matures and supply chains strengthen.

California becomes world’s largest economy to be powered by two-thirds clean energy

By /

The state released new data showing California’s continued progress toward a clean energy future with 67% of the state’s retail electricity sales in 2023 coming from renewable and zero-carbon electricity generation — compared to just 61% the previous year and around 41% a decade ago. Then, in 2024, the state added a record-breaking 7,000 MW of clean capacity to the grid, the largest single-year increase in clean energy capacity in state history.

India now gets 50% of its energy from non-fossil sources

By /

The world’s most populous nation has achieved the milestone of generating a majority of its installed electricity capacity from non-fossil fuel sources — five years ahead of its 2030 target under the Paris Agreement. India’s renewable power output rose at its fastest pace since 2022 in the first half of 2025, while coal-fired generation declined nearly 3%. The country added nearly 28 GW of solar and wind in 2024 and had already added 16 GW of wind and solar capacity by June 2025.

Solar was E.U.’s biggest source of power for the first time ever in June 2025

By /

At least 13 E.U. countries saw solar output hit a new monthly high in June, according to an analysis from energy think tank Ember. Solar amounted to more than 40% of generation in the Netherlands and 35% in Greece. Coal generated just 6 percent of electricity, a new monthly low. Fifteen E.U. countries are now coal-free, including Austria, Belgium, and Ireland. Analysts say that the June surge in solar power helped Europe weather a brutal heat wave, which saw temperatures soar upwards of 110 degrees F Analysts say that the June surge in solar power helped Europe weather a brutal heat wave.

China achieves historic 1 TW solar capacity milestone

By /

China has continued its reign as the undisputed global leader in renewable energy, with its solar capacity now surpassing a whopping 1 terawatt (TW). According to the Energy Information Administration, the total global electricity capacity in 2022 was less than 9 TW. From January to May, new solar installations totaled 197 GW, up 388% from the same period last year. In May alone, China added 92 GW of new capacity, a 105% increase from April and the highest monthly figure on record. China reached its first 1 GW of installed solar just 15 years ago in 2010.
