Japan’s agricultural sector produced 32.3 million tons of greenhouse gas emissions in 2022, accounting for 2.8% of the country’s total emissions. Nearly a quarter of that stems from enteric fermentation within livestock. Ruminants—grazing animals such as cattle, sheep and goats that acquire nutrients from plant-based diets—give off enteric methane as they decompose and ferment plant materials.
