Depends on whether you're talking about Europe the continent or eg the EU, though "many" if of course a vague enough claim to be technically true for any corner of the world.
But relateedly, US household energy expenditure is enormous compared to other countries and a lot of it is burning fossil fuels to run AC. There's a big money vs ethics tradeoff going the wrong way for emissions, more so from being a huge oil producer.
I'm interested in the numbers behind this. The location and timing of most air conditioning needs correlates strongly with the availability of PV. At this point I would have guessed that heating is strongly reliant on fossil fuels (and will be for many years to come) and air conditioning will be much greener.
