Avoid overnight shipping
Select ground transportation, instead of rush delivery, for your mailing needs and cut down on fossil fuel use and pollution.
In our harried society, it's easy to forget about Mom's birthday, or when the mortgage payment is due, until the last minute. But try to avoid overnight shipping, which burns the most fossil fuels per item. In fact, ground shipping tends to be six times more energy efficient than air.
Also, because airplanes release their greenhouse gases way up in the atmosphere, they tend to do more damage than gases emitted at ground level, at least as far as global warming is concerned.
Avoiding overnight delivery will also save you a bundle of money, since companies add a hefty price for the service.
