It will be very difficult to restrict the biodiesel credit to US consumed or produced biodiesel without it being a plain and direct infrigement of the prohibition of export subsidies under WTO rules. Europe has already opened a thorough investigation into the imports of subsidized US biodiesel which could very well lead to the adoption of a provisional tariff to compensate for the unfair advantage given to US producers. Competition should occur on a level playing field and distorsions are what cost the US taxpayers and ultimately what lead to higher prices crippling the customers’ budget.
