Brazil’s state oil company has launched two research projects on Cardano. They are intended to prevent the environmental impact of fuel from being counted twice and to allow fuel data to be traced from production through use. This is a pilot, not an industrial launch: fuel volumes and timelines for expansion have not been disclosed.
