India is exploring a mandate to blend isobutanol into diesel to lower carbon emissions and reduce the country's heavy reliance on imported crude oil. This move follows unsuccessful attempts to use ethanol for diesel blending, as isobutanol offers better energy density and lower corrosivity for heavy-duty engines. If implemented, the policy aims to decarbonize the heavy transport sector, including trucks and buses. While immediate fuel price drops are unlikely, the shift toward domestically produced biofuels is a strategic step for India's long-term energy security and climate goals.
