Two initiatives to push shipping towards zero-emission ambitions by 2050 were unveiled in the past week, setting out a vision to use green technological investment as a way to propel the world out of a coronavirus-led recession.

Ambitious Scandinavian proposals will inevitably bump up against severe economic difficulties caused by the pandemic, with many problems taking months, if not years, to iron out. Companies and countries facing financial difficulties or cash shortages will be a block in the way.

Last week, the Norwegian Shipowners' Association (NSA) set far-reaching goals for its members that included only ordering zero-emission ships within 10 years and making their entire fleet climate neutral by 2050 as part of a push for an international ban on non-carbon fuels by then.
