Danes are not 'one' but 5.6 million, they don't all share the same opinion on the environment, on shipping, or on Maersk. But I agree that Danish governments have succeeded in making Denmark appear much more environmentally progressive than is generally the case and that is a form of hypocrisy.
Not only that but look at their taxes and tariffs for cars. That is hilarious!
Only until you compare the environmental impact of shipping / ton / km to other transport modes - at which point you realise that modern container vessels is by far the most environment friendly transport mode.
You'd find the biggest hypocrites among all the consumers buying goods shipped around the world on those ships.
We won't solve global warming by finding the hypocrites. We'll solve it by knowing the problems and resolving them (or, if we don't want to work 1 problem after 1 problem, imposing taxes on petroleum usage or gas emissions, but history shows that such laws never get through).
