The Spirit of Tasmania fleet is the first Australian-based company to benchmark their environmental performance for continual improvement using the Green Marine environmental certification program. Spirit of Tasmania (operated by TT-Line Company Pty Ltd), provides both passenger and freight services between mainland Australia and Tasmania aboard the two Spirit of Tasmania ferries. By enrolling in Green Marine, the ferry operator has committed to implementing best practices that go beyond regulatory requirements, thereby demonstrating its commitment to environmental stewardship. Green Marine was established in 2007 in North America and expanded to Europe in 2020 with the consistent mission to advance environmental excellence in the maritime industry by encouraging participants to voluntarily implement sustainable best practices and technological innovations beyond regulatory compliance.
