Due to its dependence on fossil fuel combustion and the fact that it is one of the least regulated anthropogenic emission sources, emissions from the marine transport sector contribute significantly to air pollution and climate change. The European Environment Agency last March published a report on the impact of international shipping on European air quality. The main objective of the report was to provide a comprehensive review of recent literature and reports, taking into account expert knowledge, on the maritime transport sector. The report addresses the sector’s impact on air quality and climate forcing in Europe and the executive summary of the report is presented in this article.
