GRESB research

The independent GRESB research (Global Real Estate Sustainability Benchmark), conducted annually for more than ten years now, analyses infrastructure companies in terms of their performance in the areas of sustainable development plus environment protection, social responsibility, and governance (ESG).

The research serves as a benchmark for funds investing in infrastructure companies worldwide. More than 100 investors managing assets valued at above USD 22 trillion use GRESB data to monitor their investments, engage with their managers, and make decisions which lead to a more sustainable real estate/infrastructure industry. The institution which conducts the research, GRESB BV, is a subsidiary of Green Business Certification Inc., a non-profit organisation incorporated in the United States.

GTC joined the GRESB research in 2018. In 2019, in spite of more stringent requirements, GTC achieved the score of 76 out of 100 maximum points, which translated to the 1st position among 11 companies in the motorway operation and maintenance sector in Europe, and 18th position among all European companies participating in the research.

By taking part in the GRESB research and attaining a very good result for the second time in a row, GTC confirms its long-standing engagement in social responsibility and sustainable development. Year after year GTC holds and engages in numerous projects in the areas of cooperation with local communities, environment protection, and ensuring the highest safety standards for both its employees and participants in road traffic. In addition, GTC puts immense weight on ensuring proper governance standards, including ethical code, accounting, and quality, all of which lie at the base of the efficient management of the A1 AmberOne Motorway.
