The single most important thing for avoiding a climate disaster is cutting carbon pollution from the current 51 billion tons per year to zero, says philanthropist and technologist Bill Gates. Introducing the concept of the "green premium" -- the higher price of zero-emission products like electric cars, artificial meat or sustainable aviation fuel -- Gates identifies the breakthroughs and investments we need to reduce the cost of clean tech, decarbonize the economy and create a pathway to a clean and prosperous future for all. (This virtual conversation, hosted by TED Global curator Bruno Giussani, was recorded in March 2021.)

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. Get involved at https://countdown.ted.com/sign-up
