When people talk about climate change, they usually discuss the impact of carbon emissions—more specifically, the carbon dioxide that’s produced when we burn gasoline, coal, or other fossil fuels. But methane is also a so-called greenhouse gas—and it’s a big by-product of our food chain. Some of it comes out of the, um, back ends of dairy and beef cattle and other livestock; some of it is emitted when animal waste decomposes.
Whatever the source, many environmentalists argue that the world needs to make its food supply more efficient and less meat-dependent in order to curb its methane problem. Two companies on this year’s Coins2Day Change the World list are attacking the issue from different directions. Novozymes (#9 on the list) (NVZMY), a Danish bioengineering company, sells enzymes that make animal feed more digestible, and therefore more efficient. Compass Group (#33) (CMPGY), a British institutional food-service company, is reducing the amount of red meat in the millions of meals it serves every day.
