Among the 13 companies implementing tactics to
conserve fuel and/or substitute alternative fuels, six
have shifted to less polluting fuels, including biodiesel.
In its 2006 sustainability report, utility giant FPL Group
Inc. noted the recognition it received from the Council
for Sustainable Florida for its use of 2 million gallons of
soybean diesel in 2005. Seven companies are either
using auxiliary power units or changing delivery prac-
tices to reduce truck idle time, a large contributor to
fuel waste. FedEx, Johnson & Johnson and Wal-Mart
report using wider tires on their trucks, and Tyson
Foods uses aluminum wheels on its tractors, theoreti-
cally reducing road friction and thus increasing fuel
efficiency and reducing emissions. Besides implement-
ing tactics to reduce fuel emissions, FedEx is advocating
that the U.S. Senate Energy and Natural Resources
Committee establish vehicle efficiency standards that
would ultimately impact all road shipments.
