Biofuels are liquid fuels that are produced using biological sources, including sugar beet and cane, corn and soybeans. Some countries have more advanced production processes and access to more feedstocks than others, which means biofuel adoption is uneven around the world. Still, the most advanced countries in biofuel production – namely the US and Brazil – are doubling down on production as the world moves to a cleaner fuel landscape. But there is just one problem. These countries use huge amounts of food inputs such as soybeans, corn and sugar to produce fuel, so will this create a battle between food and fuel?
