What if we turned the food waste problem on its head—and made it a climate solution?
A new study finds that each tonne of food waste recycled, with existing technologies, would reduce carbon emissions by roughly a corresponding tonne.

A diverse cropping system in the US Corn Belt led to less nitrogen pollution—and an earthworm boom.
Tomatoes are the most-farmed vegetable in the world. Researchers set out to quantify the carbon footprint of this ballooning industry—and then identify ways to shrink it.
In fact, they found that per kilogram of beef, pasture-raised cattle are generally more carbon-intensive than cows raised in industrial feedlots.
“Sustainable choices aren’t just about what people want to do, they’re about what’s easy to do,” according to researchers on a new study.
A new study says the answer is yes. But the best-case scenario sits on a knife-edge of three factors: Location, location, location.
Tinkering with the enzyme Rubisco, they created plants that respond to rising levels of atmospheric CO2 with increased photosynthesis—and higher yields.
While the portrait that emerges from the unprecedented mapping exercise seems positive at first, on closer inspection it is far more nuanced.
Higher-yielding crops designed to boost food security and farmer incomes have had striking co-benefits for nature, which all stem from the preservation of land, a new study reveals.
Perhaps soon. When researchers directly measured carbon beneath commercial seaweed farms, they found it comparable to carbon captured by seagrass and mangroves.
