The number of countries, provinces, states or cities putting a price on carbon has tripled in the past year and is now at 40, including some US states, said World Bank Group President Jim Young Kim said on Monday.
One of the smartest ways to fight global warming is putting a price on carbon dioxide pollution, some key world leaders at the international climate summit say. Either a tax on carbon dioxide emissions or trading carbon pollution like pork bellies, which puts a price on carbon, will help use capitalism to get closer to a day when the world isn't adding heat-trapping gases to the atmosphere, according to leaders of France, Germany, Canada, Chile, Mexico and Ethiopia, as well as heads of the World Bank, International Monetary Fund and Organisation of Economic Cooperation and Development.
The number of countries, provinces, states or cities putting a price on carbon has tripled in the past year and is now at 40, including some US states, said World Bank Group President Jim Young Kim said on Monday. Kim and others pointed to straight carbon taxes in British Columbia, Sweden and France as examples of what works.
Economists have known since 1923 that "smart economics puts a tax on bad things and not on good things," said World Resources Institute President Andrew Steer, a former Wharton economist who wasn't part of the multi-nation initiative on carbon pricing. He compared it to taxing cigarettes to reducing consumption, although other methods of trading carbon pollution credits aren't quite the same, he added.
"We simply cannot afford to continue polluting the planet at the current pace," World Bank Group President Jim Yong Kim said. "Carbon pricing is critical for reducing emissions, preserving our environment and protecting the most vulnerable."
New Canadian Prime Minister Justin Trudeau said British Columbia's "world class" carbon tax proves such a device doesn't harm the economy. There are already costs -- called externalities -- to burning fossil fuels in terms of public health and deaths, costs that the US Supreme Court has recognized, said Wesleyan University economist Gary Yohe, who was not part of the Paris event.
"Cheap and dirty energy is not cheap for the planet or the health of our people," Chilean President Michelle Bachelet said at the Paris climate summit.
"When green taxes are incorporated into our climate policies, we can harness market forces that can lead to profound changes in our emissions patterns."
