If they don&#x27;t want to implement reforms, the obvious consequence needs to be <i>close down any operation still using leaded fuel immediately</i>. You had plenty of time.<p>Leaded fuel is an obvious externality. As with all of those, there is no pressure on the ones causing the immediate harm to stop. Government action is required.
