Transforming Ocean Shipping: Alternative Energy Sources and Practical Issues

摘要

Climate change is the top challenge of the 21 st century. Transforming ocean and inland marine shipping is essential to achieving the low- or no-carbon supply chains needed to meet the Paris Agreement's goal of limiting global temperature rise to 1.5 to 2 degrees Celsius. Shipping currently accounts for 2.9 percent of global carbon dioxide (CO_2) emissions, and the industry has committed to halving overall greenhouse gas (GHG) emissions by 2050. The magnitude of this transition is enormous for the entire industry and its suppliers and customers. But what seemed like a monumental and disruptive change just a few years ago is already evolving from a "moon shot" visionary goal to something that actually can be implemented within the lifetimes of the vessels being designed today.
