This is a bit like complaining that electric heaters are a big problem because they use a lot of energy and may contain greenhouse gas products inside them.
There are entire industries belching thick black smoke into the atmosphere because it’s slightly cheaper than the clean alternative. That’s where climate change efforts should be focused, not on the small creature comforts provided for humans so that they don’t suffer in the heat.
I’m not sure what you think is happening here, but energy is just being moved around. Air conditioners aren’t just belching out extra heat. If air conditioners were 100% efficient then they’d break even on heating, but in reality they’re much better than that, pretty much all air conditioners are at least 200% but most are more than that. This is achieved by using the same effect that your refrigerator uses - the radiator behind the freezer isn’t mega hot, right? You could look into vapor-compression refrigeration to learn more.
My point is that the anti air conditioner stuff is just greenwashing, that’s all. The facts are that air conditioning isn’t a particularly bad technology in any way.
Sure, of course, air conditioners have environmental impacts, that’s obvious - but so does building solar panels or electric cars.
Inverter heat pumps are one of the obvious solutions to mitigate climate change because they’re much, much more efficient than other forms of heating and cooling, we should be pushing for them to become common in Europe, not jumping on some bandwagon we don’t really understand because traditionally Europe hasn’t been hot enough to need it.
