Those suggesting not having guests at all, I've already written about that if you read back through the posts.
Thanks for the alternative fuel suggestions, certainly going to look into those properly. I wonder if we can get a large scale delivery to be stored at my house, otherwise I wonder if we could lobby the local kommune to get one of the local fuel stations to sell HVO or flame or something...
@wbo - Hello from Nesbyen *waves*! All the things you mention sound great and make sense if you compare a new diesel vs. a new electric. Having driven a couple of electric cars I agree they are so much nicer to drive, much cheaper and plenty practical these days.
The question is still whether it is more environmentally friendly to buy a brand new EV over keeping my dirty old VW T5 going for as long as it will. I'm still unsure however this thread has provided a lot of good info to consider both sides. I definitely like the idea of finding an alternative fuel that I could run the diesel car on to produce less emissions.
Then I'm wondering if there are some kind of exhaust of filter you can retrofit to the exhaust to reduce the NoX fumes.

@AEtR I have been involved in a couple of projects where we have retrofitted Selective Catalytic Reduction kits to large diesel power generators to meet UK emissions regs ... so it's certainly possible and productive*. For powergen sector I believe the technology has moved across from the world of agri, large tractors etc. I do not know if there is a similar capability considered viable for old vans though - perhaps a business opportunity for someone out there?
*One of our client's projects was for a 2MVA diesel generator - and iirc had NOx of ~1800mg/m3, the kit reduced that down to ~150mg/M3
I’m not really convinced with the idea of selling the old van on and it still being used or something. It just feels like I move the problem on rather than fixing it, don’t you think?
it drops down the food chain and at the bottom rung a 25 yr old rusty filthy transit is scrapped and off the road. Everyone in that chain is now driving a slightly greener vehicle
re SCR retrofits for vehicles, Do you know what the legislative framework (if any) is in Norway?
Some stuff here from Germany:

Seems to have turned into a consumer* vs (VW) manufacturer argument
German consumer groups have pressured automakers to endorse hardware retrofits to reduce NOx emissions from in-use diesel cars—instead of lobbying for customers to buy new cars—and to pay the costs.
Hardware retrofits of Euro 5 diesel cars have been enabled by technical regulations issued by the Bundesministerium für Verkehr und digitale Infrastruktur (BMVI, Transport Ministry). When issued, the regulations were criticized by Volkswagen, who advised its customers against having hardware retrofitted by third-party providers. “All of the concepts that we know of so far bring disadvantages for our customers such as increased fuel consumption and therefore increased CO2 emissions, and even a reduction in performance in some cases,” said the company.
I’d be most likely remain skeptical of their efficiency for cold-starts and short trips. Could be wrong.

*still cringe at this term because when I first heard it I was young and it seemed ominous…now I’m old and it seemed prescient.

Traffic-related sources have been recognized as a significant contributor of particulate matter particularly within major cities. Exhaust and non-exhaust traffic-related sources are estimated to contribute almost equally to traffic-related PM10 emissions.
Dear god, I can just hear the anti-disc brake bike bregade once they get a hold of that!
Wish my car was so good at emitting brake dust. All the brake dust I generate welds itself to my alloys.
