Abstract
International maritime shipping is essential to global trade yet remains one of the most challenging sectors to decarbonize. Its dependence on fossil fuels, long asset lifetimes and competition with other industries for clean energy carriers create deep structural barriers. At the same time, the sector’s emissions sit at the intersection of global and sectoral regulation, which means that climate policy can affect shipping both directly and indirectly. Because of these features, understanding how shipping transitions under different policy and technology conditions requires a framework that links trade, energy systems and the global economy in a consistent way....
