ESG
Environmental Management

We operate a dedicated environmental management organization to analyze the environmental impact of our business activities, minimize environmental pollution, and improve our environmental performance. We also strive to build an environmental management system that is better than what it was the year prior, and rely on a number of methods to achieve this: the monitoring of our environmental management system, the management of our environmental performance and progress made regarding our goals, and regularly conducted environmental risk management (i.e. reflection of organizational performance in environmental management activities).

In addition, by complying with domestic and international environmental regulations and establishing our own environmental management system, which is even more stringent than the legal requirements, we are carrying out company-wide environmental management activities, managing energy consumption and complying with environmental laws and regulations that have been put in place due to serious consideration regarding the methods through which to ameliorate the impacts of climate change.
