I really don't see the contradiction, if that 30% was true, which, really... but ok, it still would normal for the CCP to do stupid stuff because they think it makes them look modern or ecological or similar. That's why there's no need for economic sense to explain that development at all. There are also excellent non financial reasons to want to dominate that market. So to circle back, their use of trucks, which if you buy the 30% "omg lol" as they say, is in no way an argument to them making sense, neither economically nor ecologically.
