London Imposes Emission Charging

LONDON - FEBRUARY 04: A low emission zone sign is pictured on February 4, 2008 in London, England. The start of the legislation will charge operators of affected lorries, buses and coaches that do not meet the Low Emission Zone standards (unless exempt or entitled to a 100% discount) ?200 for each charging day they are driven in the zone. The scheme will eventually see drivers of the highest greenhouse gas emitting cars paying ?25 for entry. (Photo by Daniel Berehulak/Getty Images)
