Along with its practical and economic benefits, autogas is a clean-burning fuel that is better for the environment than traditional fuels like gasoline. Fleets that switch to clean autogas can help reduce emissions and establish a green image that can attract customers.
Propane autogas is listed as a clean alternative fuel in the 1990 Clean Air Act and the Energy Policy Act of 1992. Autogas vehicles emit about 20 percent less carbon monoxide and 40 percent less nitrous oxide than gasoline vehicles. Autogas vehicles also emit 98 percent fewer toxic pollutants like benzene, formaldehyde and acetaldehyde than vehicles running on gasoline. Particular matter (PM) emissions are reduced by 80 percent with autogas vehicles.
Autogas vehicles can significantly displace emissions when used on a wide scale. Autogas for America calculates that 500,000 autogas vehicles, each traveling 50,000 miles annually, would together displace approximately 150,500 tons of carbon monoxide. In a single year, these autogas vehicles would emit about 2 million tons of greenhouse gases less than their gasoline counterparts. Since fleets like taxicab companies and police departments can accumulate 50,000 miles or more a year, it’s their adoption of autogas that drives real environmental change.
A recent study by the World LP Gas Association (WLPGA) shows autogas vehicles reduce emissions of black carbon (BC), the second biggest contributor to global warming after carbon dioxide. BC warms the atmosphere by reducing the planet’s ability to reflect sunlight. However, where carbon dioxide can stay in the atmosphere for years, BC only stays in the atmosphere for several days to weeks. Therefore, cutting BC emissions through autogas use is one of the quickest ways to make an impact on climate change.
Many consumers have concerns over the environment, and addressing these is a growing priority for many organizations. Autogas has been shown to cut emissions that contribute to global warming as well as reduce harmful pollutants. By adopting this clean-burning fuel, fleets have an opportunity to mitigate some of the harmful effects of gasoline vehicles, while attracting positive attention from their communities and customers. Ultimately, the switch to autogas is a win-win situation, allowing organizations to go green, and even save some green.
