John Quiggin in Aeon:
Decades ago, economists developed solutions – or variants on the same solution – to the problem of pollution, the key being the imposition of a price on the generation of pollutants such as carbon dioxide (CO2). The idea was to make visible, and accountable, the true environmental costs of any production process.
Carbon pricing could stabilise the global climate, and cap unwanted warming, at a fraction of the cost that we are likely to end up paying in other ways. And as emissions were rapidly reduced, we could save enough to compensate most of the ‘losers’, such as displaced coal miners; a positive-sum solution. Yet, carbon pricing has been mostly spurned in favour of regulatory solutions that are significantly more costly. Why?
