If your mother, or mother-in-law, is an ardent environmentalist you might was to buy her some carbon credits for Mothers Day, especially if she is concerned about using the SUV go to the grocery store, to get her hair done, or take a trip to the Saturday Farmers Market. Carbon is a real bargain right now just ten cents a metric ton.(Click for a larger image.)
An SUV emits about 1.54 lbs of CO2 per mile. If you buy your mom and your mother-in-law $10 dollars of carbon at 10 cents a ton she would have a 100 metric ton of credits. She would have 220,462 lbs, or about 130,170 miles of satisfaction knowing she can drive just about anywhere and be saving the planet.
Of course is she drives one of those little environmental friendly cars at 0.59 lbs of CO2 per mile, she can go 373,664 miles without a worry on just $10.00 in carbon credits. She will be so proud of you.
Then again, maybe she would like some carbon futures. (Click for a larger image.)
Hummm. Maybe you should spend another $20.00 for some flowers to go with those carbon credits.
