“Rice, one of the world’s key staples, is responsible for 12 percent of global methane emissions. Now, an international team of scientists has identified chemical compounds released by rice roots that determine how much methane the plants emit…
When the research team grew these low fumarate and high ethanol (LFHE) rice varieties at various field sites throughout China, the LFHE rice produced 70 percent less methane on average compared with the elite variety from which it was bred. The LFHE crops also have high yields at yields—8.96 tons/hectare on average, compared to the 2024 global average of 4.71 tons/hectare.”
