However, as previously stated when the same comment was made. We can't encourage or help other countries to transition until we have done it ourselves. If we become world leaders in renewable, carbon free technology, it might cost a bit to sort out the mistakes but we can then export and sell that technology and knowledge. In a [cough] post brexit Britain we need to have an industry to lead in . Green energy is a pretty good one.
Not only that local pollution from cars affects us locally. Car exhausts in Bejing may increase CO2 but the particulates mainly affect those in the surrounding areas.
