U.K. emissions fall to lowest level since 1872

By / / Good news links

In a major win for climate action, a new analysis from Carbon Brief has found that the country’s planet-warming emissions fell by 3.6% to 371 million tons of carbon dioxide equivalent in 2024, the lowest since Queen Victoria’s reign. Last year’s decrease was largely driven by a drop in coal use, led by the closure of the UK’s last coal-fired power station and one of its last blast furnaces. Other contributors included a drop in demand for oil and gas and a nearly 40% rise in electric vehicles on the road.

Brazil’s crackdown on illegal mining in Munduruku Indigenous land sees success

By / / Good news links

Since November 2024, government agents have carried out 523 actions, destroying 90 camps, 15 vessels, 27 heavy machinery, and 224 engines. The coordinated government effort caused losses of $1.9 million USD to criminals. The 5.9-million-acre Munduruku Indigenous Territory, home to 6,500 people, is one of the lands that has been hardest hit by illegal mining in the country. During Bolsonaro’s administration, there was a 363% increase in the area degraded by mining which brought diseases, mercury contamination, attacks, and deaths to communities.

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

By / / Good news links

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.

Annual jab for HIV protection passes trial hurdle

By / / Good news links

An annual injection designed by California’s Gilead Sciences to guard against HIV has completed an important early safety trial, researchers report in The Lancet medical journal. Lenacapavir stops the virus from replicating inside cells. For the trial, 40 people without HIV were injected into the muscle with lenacapavir, with no major side effects or safety concerns. And after 56 weeks, the medicine was still detectable in their bodies. If future trials go well, it could become the longest-acting form of HIV prevention available.

Eastern monarch butterfly population nearly doubles in 2025

By / / Good news links

The population of eastern monarch butterflies – which migrate from Canada and the US to Mexico during the winter – has nearly doubled over the last year, according to a recent report commissioned in Mexico, generating optimism among nature preservationists. The growth in numbers for the orange-and-black butterflies follows years of ongoing conservation efforts – and perhaps provides a sliver of optimism after otherwise discouraging long-term trends for the species.

Stem cell therapy trial reverses “irreversible” damage to cornea

By / / Good news links

A new study conducted by scientists at Massachusetts Eye and Ear investigated a new treatment that removes stem cells from a patient’s uninjured eye, growing their population in the lab for a few weeks, then surgically transplanting them into the injured eye. The phase 1/2 trial recruited 14 patients to undergo the procedure. By the first checkup at three months, the corneas of seven (50%) of the participants had been completely restored. By the 12-month mark, that number had increased to 11 (79%) patients.

California now has more EV charging ports than gas nozzles

By / / Good news links

California has steadily amassed its EV charging network with both public and private charging ports over the last few years. In 2024, California boasted 178,500 total EV ports compared to around 120,000 estimated gas nozzles, according to the California Energy Commission. The number of accessible chargers across California has nearly doubled since 2022. Since August, the last time these figures were publicly updated, the state has recorded roughly 26,000 additional publicly accessible EV chargers.

Norway boosts financial support to Ukraine with €4.3 billion

By / / Good news links

The Norwegian Parliament has agreed to more than double the financial support to Ukraine for 2025 as the United States continues to withdraw its support under the Trump administration. Norway’s state budget for 2025 initially granted €2.98 billion to Ukraine. Today’s increase by 50 billion kroner boosts the total sum for this year €7.24 billion, more than doubling Norway’s contribution. None of the politicians were against helping Ukraine in its defense against aggressor Russia, from the far right to the far left.

Marshall Islands signs treaty banning nuclear weapons in the South Pacific

By / / Good news links

The Marshall Islands has become the 14th Pacific Islands Forum member state to join the South Pacific’s nuclear non-proliferation and disarmament treaty. The agreement, known as the Treaty of Rarotonga, was opened for signature on 6 August 1985 and entered into force on 11 December 1986. The current member states of the treaty are Australia, Cook Islands, Fiji, Kiribati, Nauru, New Zealand, Niue, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu, and Vanuatu.

Electric bus

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

By / / Good news links

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.
