New Efforts of the Chinese Government

• Very recently, the Chinese government has begun
  to fund research to construct technology and
  policy strategies for CO2 mitigation
• ? MOST (Ministry of Science and Technology)
• ? CAE (Chinese Academy of Engineering)
• ? NSFC (National Natural Science Foundation
  of China)
• ? Collaboration with IIASA
