I'd say party's concerned with climate change won a small victory but are still loosing the war.It's still a great victory, the biggest of them all. And an important one, as mentioned before, because we really need parties that put climate change, which is the biggest problem facing the world right now, on the map.
VVD never once spoke about climate change. D66, though considered a green party, does not have a history of fighting for the cause. Groenlinks + PvdD only managed to grow from 6 to 19 seats out of 150. Far away from the strength needed to actually change policy.
We will try again in 4 years but personally I feel we are still stagnating on progressive change as the country went with the conservative status quo (VVD/CDA) to stave off populism.
