Carbon Footprint Calculator From Delta Airlines
From Delta Airlines website:
Today, when you book a flight on Delta.com, you can make a contribution to The Conservation Fund’s Go Zero program to plant trees to offset the carbon emissions that result from your flight.
Now you can calculate your estimated annual emissions from airline miles and your personal carbon footprint online via our online Carbon Calculator.
Q: What's next? Will people start buying carbon offsets as gifts pretty soon, e.g. birthday gifts, wedding gifts, Christmas gifts, etc.? "Thanks for travelling so far to join us for Christmas this year, we bought you carbon offsets as this year's gift, to offset your carbon footprint from travelling." "Happy Birthday, I bought carbon offsets to offset some of your carbon footprint over the last year." "Congratulations on your wedding, I'm giving you carbon offsets as a wedding gift to cover some of your wedding's carbon footprint."
