This policy stipulates measures to enhance the functionality of the greenhouse gas emission trading market to encourage companies to achieve substantial reductions in GHG emissions. The definition of “market participants” who can participate in the emission trading market will be expanded to include investment traders, collective investment managers, trust companies, banks, insurance companies, and fund managers. In this amendment, the criteria for allocation cancellation have been raised to eliminate the causes that hinder reduction efforts, and improvements have been made to effectively reduce greenhouse gases. When emissions decrease by more than 15%, there is a differential cancellation. The emission trading system manages 74% of national GHG emissions, and this amendment will incentivize companies to reduce their emissions.
