Meat produced from cultured cells could be 25 times worse for the climate than regular beef unless scientists find ways to overhaul energy-intensive steps in its production.

Lab-grown or “cultivated” meat is made by growing animal stem cells around a scaffold in a nutrient-rich broth. It has been proposed as a kinder and greener alternative to traditional meat because it uses less land, feed, water and antibiotics than animal farming and removes the need to farm and slaughter livestock,…
