What are the CO2 implications of building a car, say, in Japan and shipping it to the UK versus building it here (with a high proportion of locally produced components)?

Although widely blamed on “brexit”, it’s clear that Nissan and Honda’s recent decisions to switch some future production back to Japan were more complex – and that it’s no coincidence that they closely followed the Economic Partnership Agreement (EPA) between the EU and Japan. In effect, the cars could be made more effectively in Japan and imported to Europe.

But what are the implications of shipping those new cars half way around the Earth? Are there scientific studies on the impact of global emissions (that you all agree with) on that?

I’m going to stick my head out (again!) and suggest a European built 2.0 RDE2 diesel would kick butt if the reported emissions included getting it to you – as surely they should?
