Accurately grasping environmental risks of land during operations and strengthening corporate governance! A historical investigation technology that protects social trust through transparent information disclosure.

From the perspective of corporate compliance and environmental governance, accurately understanding and managing the soil contamination risks of owned land is extremely important. This survey service is a solution for factory management that proactively identifies environmental risks on-site from the stage where there are no plans for factory closure (during operation) and implements appropriate preventive and inspection measures. By not leaving opaque environmental liabilities unaddressed and establishing a transparent information disclosure system, we firmly protect social trust from stakeholders such as investors, financial institutions, and local residents. We support advanced corporate management that fulfills social responsibilities with reliable data. This plan serves as an environmental countermeasure solution that demonstrates the safety of underground areas with solid evidence during real estate sales, sincerely safeguarding the company's social credibility and the asset value of important land. Please feel free to entrust this to us with confidence.

Applications/Examples of results

It is used for evaluating land environmental risks before the conclusion of real estate sales contracts, confirming the presence or absence of voluntary soil contamination associated with factory reconstruction or closure, and calculating environmental liabilities related to land owned by target companies in M&A (the risk of impairment of tangible transferred assets). Additionally, it serves as objective legal evidence for incorporating special provisions regarding warranty liabilities after land transfer into contracts. Furthermore, it is an extremely suitable service for preemptive measures for mandatory investigations based on regulations when the development area exceeds 3,000 square meters, as well as for preliminary analysis surveys to meet acceptance criteria for construction-generated soil (excavated soil). It is widely adopted in various business scenarios to protect corporate social credibility and asset value.
