The Clean Shipping Alliance 2020 (CSA 2020) represents a group of leading companies from the commercial shipping and cruise industries that have been leaders in emission control efforts and have made significant investments in research and analysis, funding and committing resources to comply with 2020 fuel requirements through the development and use of Exhaust Gas Cleaning Systems (EGCS). The Alliance provides information and research data to better inform industry, national and international authorities, non-governmental organisations and the public, to achieve shared environmental and sustainability initiatives across all shipping sectors.
