Northwest Airlines has dubbed its environmentally friendly program "EarthCares". There are several parts to it --
The airline is spending $6 Billion (yes, with a B) over the next few years to modernize its fleet, retiring fuel-guzzling jets in favor of more modern and more energy-efficient ones. This will reduce the airline's carbon emissions by 25%.
Also, by the end of the decade, Northwest will donate a total of $1 Million (that's with an M) to the Nature Conservancy, to protect land in the Mississippi River Valley from being polluted, developed or both.
You can support these efforts by donating either money or frequent flyer miles, and you can do it on the airline's website
