Change in the economy, just as in the climate, can be self-reinforcing, sudden, and irreversible. The world’s fastest transitions to renewable energy and electric vehicles are happening in countries where economic tipping points have been crossed in these sectors. By deliberately targeting these thresholds, we can achieve large-scale change much more quickly than we might expect. To find these opportunities, we need to move away from traditional cost–benefit analysis and adopt a very different approach to decision-making.
