Because they don’t actually want to fix the problem just find a way to take your hard earned money off you in extra taxes or fines for driving a polluting car or make you spend your money on a less polluting car ( guess who will have shares in most car companies, especially low emissions ones )
The policies they introduce either punish you for driving a car they say pollutes, or you buy a new car from a company and they make money off the share price
