While they admit that it is a "meaningless-but-entertaining milestone", TerraPass
deserves credit for reaching the 100 million pounds of carbon offset
marker this week. While people's cars are still driving them around, the TerraPass program has taken "the equivalent of taking almost 15,000 Honda Civics off the road for a year (or, ahem, 7,500 Hummers)". So, hat's off to them.
TerraPass says its goal is to offset 10 billion pounds of carbon, so they've got a ways to go (99 percent, actually). Still, their actions are making driving a theoretically cleaner thing to do, and I wish them well in their quest.
