Case Study: London’s Low Emissions
Zone
§The Low Emissions Zone “aims
to reduce traffic pollution by deterring
the most polluting diesel-engine lorries, buses, coaches,
minibuses, and large vans from driving within the
city.”
§Covers roadways
24 hours a day, seven days a week.
§Vehicles must meet
the Euro III standard for particulate matter (PM), or
else pay a daily fee of £200 to drive in the Low Emissions
Zone.
§Euro III
standards limit emissions of Carbon Monoxide (CO) to
2.1 grams per kilowatt hour (g/kWh), Hydrocarbons
(HC) to 0.66 g/kWh, NOx to 5.0 g/kWh, and PM to 0.10 g/kWh.
