The case for putting a price on greenhouse gas emissions from human activity is not arguable. It’s undeniable. But what is arguable is the best way of achieving it in the working of a modern economy. Shi-Ling Hsu, a law professor at the University of British Columbia, argues for a currently less popular way in his newly published book The Case for a Carbon Tax. “There is no policy instrument that is more transparent and administratively simple than a carbon tax.” Unfortunately its overtness tells against it politically because voters, politicians and emitting industries see the price very clearly and can calculate what they think it might cost them. But in Shi-Ling Hsu’s view environmental measures that purport to be painless are either misleading or set to accomplish nothing.
His book is grounded in the recognition that climate change is a serious problem with unacceptably high risks of catastrophic consequences that must be addressed immediately. It is alone among environmental problems in posing the risk of such vast environmental changes that the effects could destabilise entire economies, countries, and regions.
