I hear that Washington State has the highest gas prices in USA. Since I ride a bicycle, I wouldn't notice except for the news media coverage.
Conservatives tend to blame our new cap and trade system for reducing carbon emissions. They do have a point. I don't think you can just tax corporations without them passing the cost on to consumers. Cap and trade is kind of complex. I'd prefer a straight forward carbon tax. Cap and trade is more like a hidden tax.
Even with a carbon tax, the government can still provide help to folks that are lower income and harder hit; like farm workers or folks who have to commute a long ways since they can't afford housing that's closer to jobs.
Still, if we really want to reduce our carbon footprint, the cost of fossil fuels needs to go up.
