Green Options

A German study found that cows are major contributors to global warming, and it doesn’t matter if they’re raised on a conventional or an organic farm.

I’m with Stephanie Ernst over at change.org on this one, though: let’s not blame the poor cows. The culprit here is humans’ taste for meat and dairy and the sheer number of cows we have to raise to put beef on all of those plates.

The Northwest Biofuels Association has produced a joint letter about biodiesel warranty protocol intended to set the record straight for auto dealers (and everyone else that’s confused about the issue).

Recently, I wrote about how biodiesel’s new ASTM standards could go a long way in improving warranty coverage for biodiesel use in your new car. NW Biofuel’s letter goes into a little more detail, and gives you a reference you can give to your dealership or keep in the glove box. Here’s what you should know:

• Whether or not a biodiesel blend is “recommended” by your automaker is separate from the question of whether the use of biodiesel affects engine warranty coverage. Make sure you know exactly what your automaker specifies.
• Because vehicle warranties only cover parts and workmanship, fuel is not covered under any vehicle warranty.
