From the David Suzuki Foundation’s May 2004 Newsletter:
“Today’s new vehicles on average actually get worse gas mileage than they did in 1980. If the legislation had actually been proclaimed and manufacturers had been required to build cleaner cars, we would all be saving money at the pump today and our air would be a lot cleaner.” (source)
Why is an environmental group citing mileage stats? Why aren’t they worried about air quality? Could it be because air quality has increased dramatically since 1970? (See the EPA’s Air Quality and Emissions Trends Report.)
