Prof. LIU Yi is a professor at the University of the Chinese Academy of Sciences. He is the director of the Carbon Neutrality Research Center (CNRC), Institute of Atmospheric Physics of the Chinese Academy of Sciences, Chair of the China-EU Expert Group on Satellite Remote Sensing monitoring of Greenhouse Gases, and Vice Chair of the Satellite Meteorological Committee. LIU is the main organizer and contributor of the Strategic Priority Research Program of the Chinese Academy of Sciences, also known as the "Carbon Project".

His responsibilities also include design, development, and data application research surrounding the Chinese Carbon Dioxide Satellite (TanSat). He developed the high-precision inversion and flux calculation methods for greenhouse and other polluting gases from satellite measurements, and promoted breakthroughs in atmospheric greenhouse gas satellite remote sensing methods and applications in China. 

LIU has published more than 100 scientific papers in peer-reviewed journals, including Nature.

Background: 

China has committed to achieve carbon neutrality (net-zero carbon emissions) by 2060. To achieve this goal, carbon emissions must peak before 2030. This carbon neutrality strategy will be the largest formal human adaptation effort in this century, by altering the current evolutionary course of the climate system and by creating new frontiers in atmospheric and climate science. On the path toward this milestone, scientists must understand and resolve a number of issues, such as responses and feedbacks throughout the dynamic Earth system, direct and indirect impacts on climate and the environment, carbon inventories on regional and global scales, renewable energy research, and pathways optimization. Climatologists and research scientists will consider, but will not limit themselves to answering the following questions: 

1) What are the key scientific issues regarding "carbon neutrality"?

2) The gaps between climate “knowns”, “unknowns”, and applying the right research and action.

3) What databases and techniques should researchers strive to improve to support "Carbon neutrality"?

4) How to create a bridge between natural sciences and social sciences?
