The World: Chicago - BP faces boycott over toxic discharge permit

BP has come under fire for positioning itself as a "green" brand after getting a permit from the state of Indiana to dump more toxic discharges from one of its refineries into Lake Michigan.

The permit has enraged officials in Chicago and has raised the prospect of a consumer boycott of the oil giant.

Sudhu Johnston, Chicago's chief environmental officer, said: "We'd like to have them live up to their advertising."

BP has begun advertising in regional newspapers to clear up what it called "misconceptions" about the issue.
