Sustainability
External Recognition and Evaluations
Basic Approach
Under its corporate philosophy, “To give attentive consideration to both humanity and nature,” the Mitsuboshi Belting Group positions initiatives related to the environment, society, and governance (ESG) as important management issues.
The Company believes it is important not to rely solely on self-assessment of its sustainability initiatives, but to enhance their objectivity and credibility through third-party evaluations and alignment with international principles and indicators.
Based on this approach, the Company pursues continuous improvement and enhancement of corporate value over the medium to long term through various ESG evaluations and participation in initiatives.
