Measuring carbon footprints: how will China's new system work?

China is developing a nationwide carbon footprint management system—but how will it work, and will it lead to real emissions reductions? In this episode, we break down what a carbon footprint actually means, how it's calculated, and whether companies are truly cutting emissions or just using sustainability as a marketing tool, with Professor Xu Ming from Tsinghua University. He's a leading expert in environmental systems engineering. Together, we explore China's approach to tracking carbon footprints. Can this system help businesses and consumers make greener choices?
