Reasons to be hopeful: the climate solutions available now

We have every tool we need to tackle the climate crisis. Here's what some key sectors are doing

The climate emergency is the biggest threat to civilisation we have ever faced. But there is good news: we already have every tool we need to beat it. The challenge is not identifying the solutions, but rolling them out with great speed.

Some key sectors are already racing ahead, such as electric cars. They are already cheaper to own and run in many places - and when the purchase prices equal those of fossil-fueled vehicles in the next few years, a runaway tipping point will be reached.
