It is ideal for including environmental risk descriptions in integrated reports of listed and global companies, conducting asset risk inventories of company-owned land in the operation of ISO 14001, obtaining governance evidence for ESG investments, and confirming the soundness of land assets during family succession or internal restructuring.
