My guest on this week’s Wonkcast is Cao Jing, one of China’s leading experts on carbon taxes. A CGD visiting fellow and associate professor of economics at Tsinghua University in Beijing, Jing was recently the subject of a Bloomberg profile. Working in collaboration with others at Harvard University, she is developing a proposal for China to tax carbon emissions.  She is also involved with the "New Climate Economy Study" (also called Stern 2, to review economic costs and benefits of tackling climate change) led by former President of Mexico Felipe Calderón and Lord Nicholas Stern, author of the landmark Stern Report on the economics of climate change. Jing recently presented the plan at CGD’s Research in Progress seminar, and I’m delighted that she agreed to join me on the show to discuss it.
