A healthy population is essential for economic development. The poorest people on the planet tend to suffer most from the health effects from exposures to environmental hazards like air pollution and impure water. In turn, disease and disability related to polluted environments slows and blocks economic development.
Now this is how most shippers figure out the fuel surcharge on mileage. The base cost of fuel starts at $1.25 a gallon and is also based on a truck getting 5 miles to the gallon and is figured on the avg. national price of fuel as per the DOE every week.
What's more, FedEx's surcharges aren't based on fuel prices from today, or even last week. There is a two-month lag between the fuel price index and the fuel surcharge, the company explains. For example, the fuel surcharge for November 2012 is based on the September 2012 average spot price of fuel.. Likewise, UPS tweaks its surcharge once a month, and its current surcharge rates are even higher than FedEx's: 6.5% for ground shipments, and 7% for air and international packages.
