The UPA assessed 12 commercial tank terminals at Ulsan Port, based on four key categories: environmental responsibility, social responsibility (including safety), business operations, and contributions to the local community.
JSTT received the top honour for its outstanding safety and environmental management systems and significant investments in sustainable business practices.
Stolthaven Terminals President, Guy Bessant, said: "Thank you very much to the UPA for this award. We are extremely pleased to be recognised for our performance in these critically important ESG categories. Thank you also to the whole team at JSTT for their commitment to safe and sustainable practices and excellent services to our customers."
