Joe Biden has unveiled a new plan to widen the availability of petrol blended with corn-based ethanol, as the US president seeks to curb soaring fuel costs in the United States linked to the Russian war in Ukraine.
Biden travelled to the US state of Iowa, a major producer of corn and ethanol, on Tuesday to announce that he is suspending a federal rule to allow for the sale of higher ethanol blends in petrol in the coming months.
