DNV Certified
We strive to limit the impact of our day-to-day operations on the environment as much as possible and to ensure good working and employment conditions. For this reason, TTTBV has been certified by DNV from mid-2016 until april 2025 according to the CSR Performance Ladder. Because of the much wider international recognition, TTTBV has chosen to strive for ISO14001 certification during 2026 instead.
