Since returning from the UK in 2012, I has been engaged in work related to regional carbon trading pilot projects, organized the implementation of national climate projects, verification of key emission units in carbon trading pilot areas, climate change-related issues such as greenhouse gas inventories in many provinces and cities across the country, and established the National Carbon Market Capacity Building Centre. I participated in the national recycling transformation review, presided over the implementation of the Ministry of Commerce "National Economic and Technological Development Zone International Cooperation in Energy Conservation and Environmental Protection" project, the National Development and Reform Commission CDM project, the Ministry of Environment and other ministries and commissions of low-carbon energy research. I provided carbon related consulting and services for more than 60 parks and hundreds of leading enterprises across the country.
