//i can’t find anything where they say that food should not be imported//
I suggest you look harder. This is from XR’s website (which makes some quite hysterical reading in parts, but that’s by the way). It details their criticism of the UK’s current efforts to reduce emissions. Have a look at “Part 6 - Enough is enough… How are our governments letting us down?”

“Firstly, they do not include carbon emissions due to shipping or aviation, which each have a huge impact on global warming. Indeed, internationally these sectors are on track to take us to dangerous levels of warming, despite short-term reductions due to the coronavirus pandemic. See section on emissions from shipping and aviation.
Secondly, the UK’s official carbon accounting figures don’t take into account emissions contained within the goods we import, caused by their manufacture overseas and their transport to the UK – so-called embedded emissions from trade. These emissions have an enormous impact on global emissions. For example, 50% of our food is imported, and 70-80% of our fruit and vegetables. Some reports even suggest that, if we include the imported ingredients in products that are processed in the UK, up to 80% of all our food relies on foreign imports. Not to mention fast fashion and electrical goods. Not only do these imported goods produce huge amounts of fossil fuel emissions when they are being made or harvested, they also produce even more emissions when they are transported to the UK, often by air.”
Does that indicate they suggest that food should not be imported, or have I got it wrong?
These people are utter hypocrites. They engage in all the activities they say should be reduced or ceased entirely in pursuit of their ridiculous quest. Although I would still disagree with them, I may have a little more respect if they practised what they preached. But they don’t. They don’t even have the intelligence to ensure that the ”forbidden” activities in which they participate but which they demand everybody else does not are kept hidden from view. They are best ignored and those of them who insist on making a nuisance of themselves incarcerated for a lengthy spell. This is a decent start:
