In debates about politics I have often heard that environmental problems are transversal, independent on the left-right spectrum, that the environment and ecology can be defended from the left or from the right... and from an ideal, abstract, theoretical point, that's true, how could one deny that? There is no reason why a conservative should want to destroy the planet - in fact, the very word "conservative" is pretty much against that.
However, in practice, I am still yet to see a right-wing party that gives a damn about the environment. Be it at the European level, national level, regional level or even at the city level. Go to any random city in my region, read the platform of left-wing parties, and you will typically see bike lanes, bus lanes, pedestrianization, etc. Read the platform of right-wing parties, and you will see more asphalt, more lanes, more parking spaces. City-level elections are supposed to be much more about the candidate, and less about the party, but they still spontaneously group like that.
It shouldn't be like that, and maybe in some other countries it's not like that, I'm not claiming this is universal. But in my country, it certainly is like that.
