The poor in Britain are hit much harder by pollution than the rich, according to a new report produced by Friends of the Earth and the think tank Catalyst. In parts of Britain where the average annual household income is below 15,000 pounds ($25,000), there are 662 polluting factories, while in areas where the average income is above 30,000 pounds ($50,000), there are only five. If green policies are ever going to work, they must be designed with social justice in mind, says the report, which criticizes Britain’s fuel tax for making it harder for the poor to heat their homes.
