Who are these candidates with a "bold climate agenda"? I don't know any political party in any country, where I'd say 'they've got a bold climate agenda'.
Read the Wiki and well, I dont know. It may be a climate agenda, but in my opinion being green isn't necessary being bold.
Bold would be meeting at least what scientist recommend: halving emissions by 2030.
I know, that's very much to ask for any country in the world. That's why it's called bold.
What green parties all over the world are doing is: turn the rudder away from fossil fuels towards renewable energy. Which is a step in the right direction, but I think that's not bold. It's the least one can do.
This current one is very much including countries outside of the US and Green Parties have been and actually are in government in a number of countries. Also those parties are mostly not Russia friendly at all.
