What’s the fairest way to tax a hamburger?
A global tax on food emissions, mostly from meat and dairy, could cut them by 17 percent. Charging rich nations up to $969 per ton of CO2, and poor ones as little as $21, would protect the hungry.

This plastic will destroy itself in the ocean within weeks
Biodegradable plastics, designed to break down in compost, linger for a long time in oceans. Embedding them with tiny amounts of plastic-destroying enzymes speeds things up.

Less is more. So why does more feel greener? 9 studies probe the “sustainable additive bias”
Consumers judge companies greener when they add eco-friendly items more so than when they remove unnecessary ones, researchers found.

Which protein is best for the planet and your health?
A new rating system combines a “planet score” and a “people score” to see past confusing eco-labels. Tofu came out on top, and steak and cheese at the bottom.

The case for low-carbon bamboo fuel starts at $2.75 a gallon.
The fastest-growing plant on Earth can be turned into biocrude with almost no waste. A new study finds it emits 26 times less carbon than petroleum diesel.

We’re way closer to protecting 30% of the planet than we knew. But there’s a catch.
Scientists found millions of acres of overlooked conservation land, from sacred sites to watershed reserves. The world may hit its 2030 goal, just not in the right places.

The case for a more sustainable tire that comes apart on purpose
Tires are hard to recycle and shed microplastics as they wear. A modular design with a replaceable tread may offer a solution to both problems.

Magenta solar panels may be agrivoltaics’ cleverest trick yet
See-through solar cells harvest some wavelengths of light to make electricity, while passing through the red and blue wavelengths that plants need. In a new agrivoltaics experiment, broccoli yields held steady.

Could dirty, salty wastewater quench data center thirst?
Data centers need millions of gallons of water a day. Oil and gas industries produce more wastewater than that. Connecting them using today’s desalination technologies makes sense.

Scientists built a soundtrack to lure baby corals to their cyborg reef
Sounds of a healthy reef coaxed coral larvae to settle on artificial structures in Hawai’i—a possible start to “hybrid” reefs, part natural, part built.

How AI chatbots may be talking people out of climate action
Across 28,800 prompts, models were 7.5 times more likely to advise “stay the course” than “change,” even when the status quo is anti-climate.

The green revolution may be turning purple
The synthetic fertilizers behind the Green Revolution come at a steep climate cost. A sunlight-powered purple microbe just matched them in a 2-year field trial.

Researchers have made wallpaper that generates power from indoor humidity
HVAC systems burn energy pulling moisture out of the air. This wallpaper does the opposite: It cut humidity while generating electricity.

Do coyotes thrive in cities more than in the wild?
A study in Washington State found about nine times as many coyotes per area in Seattle as in remote forests.

Solar panels have (another) surprising side effect: Stopping dust storms in their tracks
In a first, researchers realistically calculated how solar farms in the Gobi Desert improve air quality in northern Chinese cities

From sundae to solvents: Chemists find a way to recycle mountains of industrial ice cream waste
The same proteins that keep a frozen pint smooth also make its fat hard to recover. A research team found an inexpensive way around the problem.

Clothes that cool you, warm you—and make power as you move
In a bid to cool people, not rooms, engineers made a printable fabric that turns body motion into electrical signals that switch on cooling and heating when you need it.

Inside the $100M AI bet to track wildlife across the Amazon in real time
Hobbled by a lack of data, scientists have been unable to track biodiversity across much of the planet. A new initiative called Amazon.ia shows how technology might help solve the problem.

How earlier toilet training could help stem the tide of plastic waste
Kids leave diapers behind nearly a year later than they did in the 1950s. With 300,000 disposable diapers tossed every minute, a new study maps three ways out.

A 100-year-old freezer rule has a hidden climate cost
Frozen food worldwide is still kept at −18°C (0°F). Raising that by just three degrees could avoid 17 million tons of emissions a year, and an 18-month study found most foods stay safe and tasty.
