All this is is a sales tax on consumer goods to fund initiatives to reduce energy consumption. It is not a carbon tax and, besides, it is so small, it would have no impact on energy use anyway. If it were truly a significant carbon tax, it might have more impact.

Albeit, I don't think local carbon taxes would be very effective since people would just transfer their purchases elsewhere.

One more proof that the opposite is also true - on some issues the actions must be on federal and even international level, otherwise we are just moving problems from the left pocket to the right.
