#shorts Kennedy then asked Litterman who provided a similar answer, saying it’s about working with other countries, but Kennedy again pressed about the possibility of China and India not cooperating.

Kennedy: “Dr. Litterman, if we spend 50 trillion dollars or however much it takes to make the United States carbon neutral by 2050, how much will it lower World temperatures?”
Dr. Litterman: “Senator, that depends on the rest of the world. We have to work with the rest of the world. We’re in this together.”
Senator: “What if we spend 50 trillion dollars, Europe cooperates, most western democracies cooperate, but India and China don’t. How much will our 50 trillion dollars lower World temperature?”
Dr. Litterman: “Senator, we have to get the world to work together. How much? I don’t know.”
Senator: “Do you believe based on your observation of Mr. Xi Jinping that he will ever do anything that is inconsistent with China’s best interests in the name of global climate change?”
“I understand that China has a federal carbon tax.”
Kennedy: “Okay, yeah. But, faced with a policy, okay, where China does something that’s not in its best interest but it does it because it’s in the global best interest, do you think President Xi would do that?

“I think that President Xi understands that we have to work together to address this global problem. Yes, I do, and it will be in the best interests of China to work with the United States to address.”

Founding partner at Kepos Capital and chair of the Climate-Related Market Risk subcommittee Dr. Robert Litterman testified during a hearing to consider “climate-related economic risks and their costs to the Federal Budget and the Global Economy.” Kennedy also asked another witness, President of the American Action Forum Dr. Douglas Holtz-Eakin, similar questions.
