Edit: am I missing something? I don’t see any discussion of the difference in energy costs for shipping concentrates vs juices, just for production of concentrates vs juices?

Actually I don't see it in the PDF, either, although the Stanford Magazine article quantifies it in a way that suggests it was reported somewhere:

Once processed, the juices have to be transported to the markets. The concentrated forms take less energy because of their compact size and substantially lower weight. Nevertheless, even the energy-intensive distribution of Not From Concentrate orange juice only amounts for 22 percent of the juice’s total carbon dioxide emission. Of course, the emissions in this step greatly depend on distance from processing plants (mainly Florida, and also California), but in most cases, this consideration is not important enough to shift the balance.

The study report itself calls itself a preliminary findings, and the reporting around it was that they'd publish full findings at some point later.

Either way, that's why I asked. I genuinely don't know the answer or whether/when the lines would cross.
