I hope not too many people base their voting decision on the amount of similarity they have in their answers with parties. The way questions are phrased do not always give parties a way to answer (Yes/No/Neutral) in the same way. As an example, 2 parties could both say No to a higher Co2-tax, but one of them does so because they claim climate change is a hoax, while the other one has a problem with it not being progr…
Another problem is, that currently most parties are claiming to care all about the climate and would immediately take steps to fight the climate change after the election. Just if two of those parties have been in power for the last 8 years, you might want to weight their statement accordingly :)

Of course, a cynic would say that's just an excuse for delaying, and a trick to play both sides...
