The American climate bill which has just cleared the Senate adopts what promises to be the only feasible approach in the present social environment. The emphasis is on cash incentives (can we say 'bribes'?) to households and businesses to adopt greener practices aimed at reducing 'greenhouse' gas emissions by 40% by 2030.
In a world where so many of us resent being preached at, or suspect hypocrisy - say from celebrities jetting around the world - the incentives method has three huge advatages: First, it demonstrates serious intent , with the Federal government (most of whom are after all taxpayers) putting serious money behind their mouths; second, it displays understanding that many families and businesses will find it difficult and expensive to convert homes and premises and offers help with that, and; third but not least, it makes clear that no one is setting themselves up on a higher moral plane and preaching down to the plebs from the pulpit. Millennia of conditioning about ethics endures that we don't regard someone offering us incentives as a particularly saintly or virtuous person. Presumably that point applies to US administrations also. Aided by the tax system they confer this benefit on the whole people, not just the rich.
The self-same moral confusion and suspicion that has led us to rely so much (too much many would say) on markets for values now makes the American approach to tackling the climate crisis look like the only way to go.
