We have converted all of our truck fueling facilities to
emission-reducing biodiesel fuel, which is a blend of 20 percent soybean oil
and 80 percent ultra low-sulfur diesel.
Company vehicles will be transformed over time as vehicles come
up for replacement, initially replacing them with available hybrid and
alternative-fuel vehicles, and later with even newer technology as it becomes
Existing hybrids use both an electric motor and a standard
gasoline or diesel engine. While the cost of hybrid vehicles is greater than
that of conventional vehicles, we know there is great value for
the environment by helping reduce carbon monoxide pollution.
To further reduce carbon
emissions from our fleet, we switched to biodiesel fuel. Biodiesel is available
at all 13 PHI-owned fuel sites, which are strategically located throughout the
area. We have approximately 1,000 diesel powered vehicles in our fleet.
