California and Texas rank First and Second in population, respectively, and both are under tremendous pressure by the EPA to regulate the emissions generated by their large manufacturing industries. Both states can earn pollution credits by indiscriminately crushing old cars in lieu of actually reducing emissions. Additionally, California and Texas both offer credits or vouchers that encourage people to trade in older cars that have failed emissions tests. Despite each state's bustling car culture, their silly scrappage policies prevent them from making our list. Fortunately, no other states sponsor similar programs.
