§ Lord Jenkins of Putneyasked Her Majesty's Government:
Whether it is the case that Sainsbury's City Diesel pollutes substantially less than other diesel fuels and if so whether fuel of similar quality is available from competitive suppliers.
§ The Parliamentary Under-Secretary of State, Department of Transport (Viscount Goschen)City Diesel sold by Sainsbury's does give significant reductions in some pollutants compared with conventional diesel fuel. It is not available from other retail outlets; but some competitors sell different specifications of diesel fuels which also produce reductions in emissions.
