Like so many countries around the world, Vietnam is hoping to reduce its impact on the environment. The nation has set a goal to reduce its greenhouse gas emissions by eight percent by 2030, and it’s planning to ban Hanoi's beloved motorbikes to get there. But Vietnam isn’t just targeting the vehicles that pump so much exhaust into its cities. It’s also considering the fuel itself.
According to Quartz, the country is encouraging residents to swap their wood-burning stoves for biogas — and not just any type. Biogas is a biofuel made from organic matter, such as food scraps or grass trimmings, and in this case, the biogas is coming from pig waste.
This unconventional fuel source actually makes a lot of sense for Vietnam, since pork is the largest piece of the country’s meat production. It makes up 72.6 percent of that sector, World Bank reports, with poultry trailing at a very distant second place at 18 percent.
