Materiality reporting

We identified 16 factors as material to our business and these were mapped against the four strategic pillars.

Our approach to determining materiality

The assessment of GMT’s material Environmental Social and Governance (ESG) factors was carried out in line with a Global Reporting Initiative (GRI) Standards approach. Although we have not followed the GRI Standards for this report, we felt it was important to base what we have done on an internationally acknowledged and respected benchmark.

This assessment was then canvassed with senior staff and selected stakeholders including investors, customers, suppliers and industry representatives. From there, we developed a materiality matrix based on the extent to which each factor influences stakeholders’ decision-making and the significance of those factors to our success.

Mapping our materiality matrix back against our business model

All 16 factors are important contributors to the long-term performance of our business. In terms of ranking, the most significant factors for us were positioned in the upper right quadrant. These factors had the greatest influence on how our stakeholders assessed us, and were also those we judged most important for GMT economically, environmentally and socially. The six most important included, customer relationships, sustainable development, resilent property portfolio, capital structure and financial results, along with health ans safety. These six areas are the focus of GMT's corporate reporting.
