Weekly Economics Podcast: Can we tax our way to a cleaner planet?

One of the most fashionable economic ideas of the past decade has been ​‘nudge’ theory – the idea that a little prod from government can encourage us to change our behaviour and be better citizens, maybe without even realising it. Meanwhile, good old-fashioned regulation seems to have been decidedly out of favour with recent governments – and leaving the market to just do its thing isn’t all that popular with campaigners.

When it comes to the environment, do all of these approaches have their place? What works best? And are there better or worse ways to make sure our economy doesn’t wreck the planet?

Ayeisha Thomas-Smith is joined by Dave Powell, head of environment at the New Economics Foundation, and Alice Bell, director at climate charity 10:10.
