This means war...

I've been reading through the Carbon War Room shipping battle. It is indeed quite interesting read. Of course, by nature, shipping is the most environmental means of transport, but that should not be an excuse for not improve. Most probably major efforts are needed from IMO as well as flag states, port states and the major owners/operators to drive the changes needed.

“SHIPPING > Situation
Lack of visibility and lack of sovereignty explain in part
why the shipping industry’s destructive pollution has escaped regulation to
date. Ships account for an estimated 1.3 billion tons of CO₂e annually,
or close to 3% of global anthropogenic emissions, in addition to emitting black
carbon soot, a leading cause of Arctic ice melt, and NO_X and SO_X.
The shipping industry is the largest emitter of NO_X and, producing
an equivalent amount to 800 million cars annually, and also one of the largest
emitter of SO_X. Under business-as-usual, harmful emissions from this
sector will continue to rise as demand for freight increases. Emissions of CO₂e
are contributing to rising atmospheric concentrations of CO₂e that
lead to catastrophic climate change.”
