	abstract={Biofuels are promoted worldwide as a strategy to replace fossil fuels and cut greenhouse gas emissions. However, their climate benefits are uncertain because biofuel production can induce deforestation and other land use change that causes carbon emissions. Here we show that global demand for biomass-based diesel fuel between 2002 and 2018 drove the conversion of approximately 1.7 million hectares of forest to oil palm in Indonesia and Malaysia, which is about one-fifth of the total forest-to-palm expansion during this period. Using econometric models and high-resolution satellite data, we demonstrate that biomass-based diesel demand raised palm oil prices, which in turn accelerated deforestation, primarily in natural forests. The associated land-use change released more than one gigaton of CO2, giving biomass based diesel higher carbon emissions per megajoule than that of fossil diesel. These findings indicate that biofuels derived from vegetable oils have likely increased, rather than reduced, global emissions, and highlight the urgent need to shift renewable fuel policies away from crop-based feedstocks.},
