In 2008, the British Columbia Liberal Party, which confoundingly leans right, introduced a tax on the carbon emissions of businesses and families, cars and trucks, factories and homes across the province. The party stuck to the tax even as the left-leaning New Democratic Party challenged it in provincial elections the next year under the slogan Axe the Tax. The conservatives won soundly at the polls.
Their experience shows that cutting carbon emissions enough to make a difference in preventing global warming remains a difficult challenge. But the most important takeaway for American skeptics is that the policy basically worked as advertised.
