Sanity of the car scrappage scheme

TO argue that the car scrappage scheme was “not a cost to the state” because it generated net revenue for the government, as Alan Nolan does (Letters, June 22) is wrong.

As Mr Nolan knows, every single car purchased here is imported, and represents a net economic leakage to the economy as a whole. We cannot import our way out of recession.

Mr Nolan ignores the massive CO2 emissions generated in car manufacture and distribution.
