Why Net Zero?

Everyone has agreed that Net Zero is a good idea, without necessarily agreeing what it means, still less on how to get there. This series of lectures looks at the science behind it, how climate impacts are emerging, and when and how we need to act to turn things around.

Both the science, and the policy challenge, of achieving net zero are far simpler than many are led to believe. Simple does not mean easy, which makes it all the more important that everyone should understand both why and how we need to get to net zero: you shouldn’t have to take a scientist’s or politician’s word for it.

Reducing the problem to its essentials – how to stop fossil fuels from causing further global warming – should help you form your own views on which policies are actually going to work.
