Safe
for ozone action days. Converting small utility
engines such as lawnmowers to burn propane instead of
gasoline can reduce emissions of ozone precursors by one
third and increase fuel economy by 14 percent (Cotton,
1992). According to the U.S. Environmental Protection
Agency, a typical four-horsepower gasoline lawnmower engine
generates almost six times as much volatile organic compounds
(VOCs) per hour of use as a typical car.
Clean enough to use indoors.
LPG forklifts can reduce emissions of indoor and urban
air pollutants, especially emissions of particulate matter
compared to diesel and carbon monoxide compared to gasoline.
“Overall, the urban air-quality benefits of LPG are
similar to the benefits of CNG (generally considered the
cleanest of the fossil-fuel alternatives.)” (Delucchi,
1999). |
