Can you name the countries with the most successful green parties?
Measured by percentage of seats in legislature (lower chamber if applicable) won by green parties in the most recent election, and percentage of popular vote
Some countries do not have popular vote information available
Mostly based on this Wikipedia list, which is based on how the parties describe themselves, though I removed some that didn't seem to be actually green parties and added missing others
Interesting that those countries most at risk from climate change (low lying island nations) do not appear on this list. Rather it is mostly wealthy European nations.
Perhaps in, say, Oceanian island nations, the major parties focus more on environmental issues than in other places, but just not enough to make it their primary focus or to make them "green" parties?
At the last election in Australia, Greens secured a total of 15 of the available 221 seats across both houses of parliament or 6.6%. Do they not appear on the percentage of seats table because you are only counting the lower house?
