A persuasive article by Charles Komanoff in Salon argues for a carbon tax:
Their model is British Columbia, Canada’s third most populous province, which began taxing carbon emissions in 2008. The tax rate now stands at $25 per ton of carbon dioxide (Canadian currencies and weights have been converted to American). That is probably close to the limit of what a single state or province can charge on its own without driving carbon-taxed shoppers or businesses to neighboring states.
Six years on, the tax is a smashing success. On every indicator that matters ― emission reductions, economic output and jobs ― B.C. is outstripping the rest of Canada.
