Lucas Joppa, Microsoft’s first chief environmental officer, thinks about climate change through the lens of coding, and he says the world’s current net-zero approach simply won’t compute. So how do we create a system that actually accounts for all the world’s carbon emissions — and helps us get to zero (as in zero additional carbon added to the atmosphere by 2050)? Joppa shares three “bugs“ in our current net-zero code, a four-point plan for fixing them – and how logic can help us change the current course of climate change. Countdown is TED’s global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world.
