"In con- struction this will include measuring the impact of electricity usage at shipyards and the footprint of materials and equip- ment, including energy use in steel pro- duction and materials’ logistics. LCA will likely also introduce a lot of new environmental impact considerations – for example, acidi? cation of land around shipyards. Very little consider- ation is given to such things today."

Buzuku says LCA may show a bias towards Northern Europe, where yards have access to cleaner energy, but the reality of shipbuilding is 60% in China, 25% in Japan and 20% in Korea. "Some
