2、require zero-emission capable vessels(ZECVs).Most of these vessels would likely be built in China,Republic of Korea,and Japan,which collectively dominate the shipbuilding industry,especially for large cargo ships.Because ZECVs are more expensive than conventional vessels,this presents an economic op
