Shipbuilding
Shipbuilders and marine equipment suppliers play a crucial role in responding to increased demand for alternative fuels and technologies and delivering new vessels on time. The OECD Shipbuilding Committee provides an overview of the current state of the shipbuilding industry. Find out more on the OECD website.

Maritime Decarbonization and Digitalization
Trends in low-carbon patenting in maritime technologies (2005-2021)
Low-carbon maritime technology patents have seen an increase from 2005 to 2021, with a peak in 2015. Despite this growth, the share of climate-related patents in maritime technologies has stagnated, reverting to levels similar to those seen in 2005.

Trends in low-carbon patenting in maritime technologies in selected economies (2005-2021)
The countries patenting the most low-carbon maritime technologies include the EU-27, Japan, Korea, the United States, and China. Each country exhibits distinct technological focuses; for instance, the EU patents most in renewable and hybrid-electric solutions, whereas Japan emphasizes watercraft hull designs. Since the late 2010s, China has emerged as a leading innovator.
