Since Planktos was the official carbon neutralizing agency of the Chicago Green Festival, Russ George (our CEO) was asked to give a public speech at the event.
On the way back to the aiport after the festival, Russ told his taxi driver about the trip. Moved by our company's mission, the taxi driver accepted payment of the cab fare in the form of carbon offsets for the taxi.
I find this wonderfully hilarious. And good for the jolly green cabbie.

Buy one pound, get one free!
Today, I purchased a package of grapes. On the label of the grapes, it says that the fruit was “grown in Chile.”This doesn't surprise me. In my birth-given rights as a wealthy American, I deserve to consume any piece of food I feel like consuming at any given point in time, even if this requires shipping the piece of food halfway around the world for my personal self enjoyment. Obviously.
So, how much CO2 is produced by shipping grapes around the world? Let’s find out.
Some rough estimates:
The middle of Chile is about 5270mi from the middle of the US.
A 747 cargo plane uses about 6.8 gal/mi. Yikes.
At full capacity, a 747 can carry an impressive 450,000 pounds of cargo.
So, we use a little math magic and we get
(6.8 gal/mi x 19.4 lbs of CO2/gal gasoline x 5270 miles) / 450,000 lbs cargo =
1.5 pounds CO2 per pound of fruit
This is actually much less than I had expected. To put this number into perspective, the average American produces a whopping 122 pounds of CO2 daily. Although, eating grapes in April is rather unnecessary, and every pound I can keep out of the atmosphere makes a difference.
I’ll make up for myself at the farmer’s market this weekend, to free myself of liberal guilt.

Green is good in any shade
‘Green’ is not synonymous with ‘elite.’ It’s not a club, it’s not exclusive, and there are no rules to being green. Every person who ever recycled a bottle or rode a bicycle is helping to some degree, and any shade of green is better than none at all.
The reason I say this is because recently, I have witnessed environmentally conscious people criticizing one another for the way they practice their beliefs. I heard a bicyclist talk down to a carpooler. I saw a vegetarian sneer at a meat-eater… in an organic restaurant. Even Al Gore is being criticized for using too much electricity, as if his impact as a public speaker does not do enough for the planet.
This phenomenon is especially confusing to me. I’m sure Snoop Dogg uses just as much energy as Al, and he’s not getting criticized for it. Even President Bush gets by without having his energy bill scrutinized. If Al is a bad person for heating his swimming pool, then I am a better person than my vegan friend, because she once killed a mosquito while we were camping. (Even though I was eating a hamburger.)
When it comes down to it, we are fighting a difficult battle, and we are going to have moments of frustration. Let us channel that frustration into warmth and encouragement, instead of separating into Yankees and Dodgers. With a little love, we can inspire a Hummer-driver to stop at the local farmer’s market. And that is a good first step.
(And while we’re at it, let’s make sure Snoop Dogg keeps his tires properly inflated.)

Watt's your problem?
Sometimes people ask me why global warming focuses on CO2 instead of heat. When I burn gasoline, doesn’t it produce heat? Isn’t heat responsible for global warming?
When you drive your car, fuel gets burned and a lot of heat is produced. In order to keep your engine cool, this heat gets sent through the radiator, where it gets released into the atmosphere. This warms the air around your car and keeps your car cool.
Despite this, the amount of heat released into the atmosphere while driving is very small when compared to the amount of heat trapped by carbon dioxide. Let’s look at some numbers to make sure.
World-wide, we are using somewhere around 6 x10^12 (6 million million) watts of energy at any point in time. That’s a whole lot of light bulbs. Since burning fuel usually makes more heat than useful energy (about 3 times as much), we’ll estimate that 18 million million watts of heat are being produced at a time. Yikes!
Now let’s compare that to the amount of heat being trapped by greenhouse gases. According to the most recent IPCC report, the atmosphere captures 1.6 watts/square meter more heat than it did before the industrial revolution. That means for every square meter of space on our planet, 1.6 extra watts of sunlight are warming the atmosphere. How much heat does that produce? Well,
1.6 watts/sq meter x 510 trillion square meters on our planet =
816 million million watts of heat trapped by greenhouse gases
That’s a whole lot more than we calculated for burning fuels.
Maybe heat produced by a car engine or a power plant is enough to warm the earth, but I am pretty sure that greenhouse gases are responsible for our hyper-speed climate change. At this very moment, greenhouse gases are warming our planet 45 times more than the burning of fuels.
