This is a law being enforced by the green party. That all other parties is on board is simply because everyone needs the greens to get to power - despite they having only less than 7% voted for them. They are the only party that have supported both the bloc in the parliament in the past.
Rest of us 93% hopes that they will fall below 4% votes in our election next year (it looks hopeful) and be gone from the parliament.
Most citizens doesn't agree on this law. We understand that it will hurt us enormously economically, make it impossible to live on the countryside (a place that the green party openly despise) and that it in the grand scheme of things will do zero since China continues to build coal plants.
