Honestly, I think auto manufacturers and oil companies should charge just a little extra to fund carbon reductions and carbon offsets. Since that isn't happening anytime soon, I started looking into purchasing offsets for my own truck.
There are a few outfits out there that either do carbon reductions (plant trees) or carbon offsets (help renewable energy projects). But for ease of simplicity, and because I think there are a lot of organizations planting trees out there already, I purchased a TerraPass.
It's nice to know that, though I'm driving a truck that's emitting carbon into the atmosphere, I'm also doing something to more than negate it's effect on global warming.
