Five companies in Britain produce more carbon dioxide pollution together than all the motorists on UK roads combined, according to new figures which reveal heavy industry's contribution to climate change...The top five companies (EON UK, RWE Npower, Drax, Corus, and EDF) produced between them more than 100m tonnes of carbon dioxide in 2005...A spokeswoman for EON said: "We are one of the leading green generators and invest more per customer in green energy than any other major supplier in the UK." A spokesman for RWE Npower said: "We're one of the UK's biggest power generators, so of course we're going to have more emissions than, say, a single power station somewhere. The test of 'green-ness' is how much you are changing."...British sites operated by Tesco, Walkers [part of PepsiCo], Ford, Unilever, Kellogg's, Allied Bakeries, Nestle and Cadbury Trebor Bassett [part of Cadbury Schweppes] are among those that emitted more than 100,000 tonnes of CO2 in 2004...[Business & Human Rights Resource Centre invited EON UK, RWE Npower, Drax, Corus, and EDF to respond to the allegations. EDF Energy response is below. EON UK, RWE Npower, Drax and Corus declined to respond]
