Londoners generate less waste per household than any other region in England, according to a new report.
The report, The Environmental Effectiveness of London , found that in London in 2002/3 household waste in London was 0.46 tonnes per capita, while the average for other regions was 0.53 tonnes per capita.
London mayor Ken Livingstone said: "Like most cities, London faces formidable challenges in improving its environment and reducing the impact it has on the rest of the country. But often it is the big cities where innovation to improve the environment first takes place.
The report also looked at other environmental impacts including emissions, energy consumption and water use.
