I read that during a conference about climate change, the chauffeur of Haakon waited about 90 minutes with running engine for him!
Senseless, Haakon, really senseless
I'm not sure Haakon deserves to be scolded, unless the engine was left on at his direction. And considering that Haakon appeared to take the Scandi heirs' climate trip the most seriously of the three and has purchased and been seen driving environmentally friendly cars, I think he deserves the benefit of the doubt that he didn't sanction that.
The palace spokesman said there's no policy that engines be kept running while the royals are performing their duties, so this sounds like the driver being an idiot to me.
