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.

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.

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.

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.

Canada to build massive, fully electric, 185-mph inter-city rail network

By / / 🌐 Good news links

Canada is set to begin work on a high-speed inter-city rail network – the largest infrastructure project in the country’s history. Spanning 621 miles, the fully electric new rail network will serve 18 million people – nearly half of Canada’s population – across the Toronto-Quebec City corridor. It’s expected to serve 13 times more passengers annually than the current service. Canada is expected to invest nearly $3 billion USD over the next six years to bring the project to light.

France runs fusion reactor for record 22 minutes

By / / 🌐 Good news links

Achieving the dream of commercial fusion power is the Holy Grail of engineering and has been for 80 years. With a single gram of hydrogen isotopes yielding the energy equivalent of 11 tonnes of coal, a practical fusion reactor would hold the promise of unlimited, clean energy for humanity until the end of time. France has upped the ante in the quest for fusion power by maintaining a plasma reaction for over 22 minutes – 25% longer than the previous record set by China in January 2025.

Global sales of combustion engine cars have peaked

By / / 🌐 Good news links

To decarbonize road transport and achieve global climate goals, the world must move away from petrol and diesel cars and toward electric vehicles and other forms of low-carbon transport. Fortunately, this transition is already well underway, with global sales of combustion engine cars peaking in 2017 or 2018 and now falling. In 2018, global combustion engine cars peaked at more than 80 million. By 2023, sales had fallen below 65 million units as EV sales rose dramatically.

Norway is set to become the first country to fully transition to electric vehicles

By / / 🌐 Good news links

Despite its vast oil and gas reserves, the Nordic country has long been recognized as a global leader in sustainable transportation. Its EV sales have increased from less than 1% of total auto sales in 2010 to a whopping 88.9% last year — and this trend doesn’t show any sign of slowing. Data published by the Norwegian Public Roads Administration found EVs accounted for more than 96% of new cars sold in the first few weeks of this year. It puts Norway within touching distance of going fully electric — realizing a non-binding goal that was first established by lawmakers back in 2017.

China sets new fusion endurance record of over a thousand seconds

By / / 🌐 Good news links

Fusion power is widely thought of as the holy grail of renewable, climate-friendly energy. Now, we are one step closer to realizing practical fusion power for the masses. The Experimental Advanced Superconducting Tokamak reactor in China’s Anhui Province has set a new record with a 1,066-second sustained fusion reaction. The new record builds on the previous record of 403 seconds set by EAST in 2023. The increase was made possible by a number of upgrades to the experimental system that have doubled the power output while keeping the reaction stable.

Heat pumps

Carbon-friendly heat pumps now outselling gas furnaces in the U.S.

By / / 🌐 Good news links

Americans bought 37% more heat pumps than the next most popular heating appliance — gas furnaces — during the first 11 months of 2024. That’s a 21% increase over 2023. In addition to providing heated air in the winter and cool air in the summer, they are far more efficient than conventional heat sources — delivering three to four times more heat per dollar spent than oil- or gas-fired heating equipment or old-fashioned electric baseboard heat. To decarbonize the economy by 2050, heat pumps need to be 100% of heating system sales.
