Meet the startup helping farmers tackle the problem

Rice feeds nearly half the world's population, but the way we grow it has a surprisingly high methane footprint.

According to a report by the Global Climate and Health Alliance, eight percent of the 42 percent of global methane emissions caused by agriculture come from rice cultivation.

Farmers produce rice by flooding their rice fields, which creates anaerobic conditions in which microorganisms methane - a potent greenhouse gas with a warming potential 80 times that of CO2 during the first 20 years after it is emitted.

Methane's short-term power makes it a major driver of global warming, but it also ...
