Our Materiality Initiatives

TBK Group's Material Issues

The TBK Group has identified the following as its material (key) sustainability issues.

materiality

Materiality Identification Proces
We identified relevant social issues by referencing global frameworks such as ISO 26000, the GRI Standards, and the SDGs, while also taking into account changes in the business environment and global megatrends.

These issues were then evaluated using a two-axis approach:

● Importance to our business, and
● Importance to external stakeholders such as investors, customers, and local communities.

Based on this evaluation, we created a Materiality Matrix.
From the matrix, issues with the highest relevance were selected as materiality candidates.
Finally, after discussions and approval by the Board of Directors, our material issues were formally identified.
