On October 24, the General Manager of Beijing Green Exchange and Secretary General of the Beijing Green Finance Association, Mei Dewen, said this at the "2021 Global Wealth Management Forum" hosted by Caijing Magazine and Caijing Think Tank.

Mei Dewen pointed out that according to the well-known Kaya model, a country’s carbon emissions depend on the number of population, per capita GDP, energy intensity per unit of GDP, and carbon intensity per unit of energy. In this sense, China‘s “carbon neutrality” faces three major challenges: macroeconomic transformation, energy transformation, and financial transformation.

Mei Dewen stated that the effectiveness of the carbon market depends on "strict policies, accurate data, and lively markets." First of all, the policy must be strict, that is, strict legislation. Because the carbon market is a quota market, the future carbon trading market needs to move from the current intensive emission reduction to the absolute total emission reduction, so it must be strict; second, the data must be accurate, that is, rigorous quantification. Because the carbon market is a virtual market based on the energy statistics system. If there are problems with energy statistics, monitoring, and analysis, there will be problems with the authenticity, completeness, and accuracy of the data, which will be a disaster for the carbon market; third, the market must be lively, that is, serious pricing. Only when the market is alive can there be liquidity and scale, and the price can reflect the true marginal abatement cost of carbon emissions, comprehensive social cost and externality cost.
