All subsidiaries are guided under the Guidelines for the Investigation and Disposal of Hidden Hazards from Environmental Emergencies in Companies and the Administrative Measures for the Registration of Emergency Plans for Environmental Emergencies in Companies and Public Institutions released by the Ministry of Ecology and Environment to formulate their own investigation and governance regulations for environmental hazards and emergency response plans for environmental incidents. Through centralized investigation of environmental risks and hidden dangers, we acquire a full understanding of hidden environmental risks, register hidden risks and assess the current situation, formulate and enforce rectification measures, eliminate various hidden environmental risks, and prevent and reduce the occurrence of similar incidents. We also establish a monitoring and hierarchical management system for key environmental factors to effectively prevent the occurrence of major environmental pollution incidents.
