Study shows China can be carbon-negative in an economically competitive way

If we’re going to limit global temperature increases to 2 degrees above preindustrial levels, as laid out in the Paris Climate Agreement, it’s going to take a lot more than a transition to carbon-neutral energy sources such as wind and solar. It’s going to require carbon-negative technologies, including energy sources that actually reduce carbon dioxide levels in the atmosphere. While most climate researchers and activists agree that carbon-negative solutions will be needed to meet the goal set in Paris, so far most of these solutions have been viewed as impractical in the near term, especially for large, coal-reliant countries like China. Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Harvard-China Project on Energy, Economy and Environment, in collaboration with colleagues from Tsinghua University in Beijing and other institutions in China, Australia, and the U.S., have analyzed technical and economic viability for China to...
