Go Green with an -airline-? Its a nice thought, but it struck me funny that JetBlue is advising you to reduce your impact.
* Note their list does -not- include 'stay home' :
Plant shade trees to protect from summer sun.
Explore installing a solar water heater for your home.
Encourage recycling efforts.
Re-use envelopes, jars, paper bags, scrap paper, etc.
Join a car pool or use public transport.
Reduce your use of air-conditioning.
Rent or borrow items that you don't use often.
Start a garden; plant a garden instead of a lawn
Compost kitchen waste, or give it to a friend who can.
I can just hear it... "Happy St. Patrick's Day!... I wanted to give you something that would turn green (eventually) so here's my kitchen trash!?"
