Strategies for achieving net-zero emissions climate goals have emphasized an important role for bioenergy to displace fossil fuels and for carbon-dioxide (CO<sub>2</sub>) removal from the atmosphere. Soil carbon sequestration is one of the key approaches for using the vast potential of land as a sink for atmospheric carbon. Carbon mitigation could be as high as 4 billion to 8 billion tonnes of CO<sub>2</sub> per year with near complete deployment globally of practices that enhance soil carbon sequestration with crop production. However, there is a disconnect between renewable energy policies to promote the production of low-carbon biofuels and conservation policies that promote soil carbon sequestration practices. We propose that any "climate-smart" biofuel policy should consider farm-specific values of emissions from biofuel feedstock production and soil carbon sequestration and incentivize the adoption of climate-smart practices. This could provide lessons and develop capacity that may help expand policies and practices to agriculture more broadly.</div>
