I can see that, if it is restricted to British vessels, it is perfectly within the powers of this Parliament, but I am not at all clear
that it would be right to impose that kind of obligation on British vessels without attempting to encourage foreign vessels to do the same. As I mentioned at Second Reading, something like this is already happening, and in pretty small ports—though they have a large amount of traffic, usually overnight, when refrigerated vehicles go straight to Europe and arrive quickly at their markets, which are pretty hungry for the result.
