We continue to transform our vehicle fleet by adopting
low-carbon technologies such as hybrids, plug-ins and biodiesel fuel in those
vehicles that have diesel engines. We acquire commercially available hybrid and
alternative fuel technology when a vehicle needs to be replaced. We research
new vehicle technologies for compatibility with our fleet requirements and plan
to introduce them as they become available.
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.
