Economic benefits of building zero-emission capable vessels in East Asia

Abstract

Achieving net-zero greenhouse gas (GHG) emissions from international shipping by or around 2050 will 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 opportunity for shipbuilders and shipbuilding countries, especially for first movers that gain a competitive advantage in the marketplace. In this paper, we provide an overview of the shipbuilding market and existing government support measures for the industry in China, Republic of Korea, and Japan. We then estimate the additional revenues these countries could earn by building ZECVs instead of conventional vessels.
