The 2 Rules for Eating to Fight Climate Change

After wasting less food and eating less meat, all other changes a person might make are marginal, experts said, among them eating locally, organically, and seasonally. Moreover, the climate impact of those food choices is in many cases contradictory. “I work in food, and it’s confusing for me,” Cabrera, of the NRDC, told me. “Is this lettuce better than this lettuce? Consumers are faced with so many choices, and it is really hard to know.”

Humanely raised, local meat, for instance, can produce more emissions than meat coming from a concentrated industrial operation, Clark told me. Cows

Scientists Say Jet Fuel Made From Food Waste Could Slash Aviation’s Climate Impact

Within a few  years, food waste could be fueling our airplanes. 

Researchers have worked out a way to transform food scraps, used cooking oil, animal manure and wastewater sludge into jet fuel with a carbon footprint 165% lower than standard jet fuel, according to a new study published in the Proceedings of the National Academy of Sciences.

The emissions savings come from diverting the food waste from landfills, as well as from avoiding using fossil fuels. This “reduction in lifecycle greenhouse gas emissions would provide a path toward net zero jet fuel,” says the report. 

The aviation sector has pledged
