Global CO2 Price of $50 May Avert Climate Catastrophe, MIT Says

A global carbon price of $50 a metric ton may be enough to limit catastrophic climate change, according to the Massachusetts Institute of Technology.

China, the world’s biggest emitter, is crucial to curbing emissions to limit temperature rises to 2 degrees Celsius (3.6 Fahrenheit), according to a study published in the Energy Economics journal. Emissions reductions elsewhere will be more expensive without having China’s participation in a global climate treaty, according to the research.
