Oh yes, they are failing, and I can explain you why. We are in a deadlock in my country regarding elected representatives because the baby boomers vote and they are in greater number than us youngs, so the policy will always be conservative and economically liberal. Basically old conservatives control our future even if they have less life remaining than us on this Earth. (That's how I conceived a new democratic process by the way - amount of votes = number of years remaining in your life expectancy. Maybe a first solution offered to you to give younglings a chance about their future ?). Democracies do have power, but they lack a lot of will.

Add to that lobbies and economic agents controlling elected officials so they keep believing in the eternal growth lullaby, and yes - they ARE failing to implement laws that curtail CO2 emissions by rich people/powerful corporations. I really don't see how that's surprising or subject to debate - everything observable around us is in favor of this argument.

I'm not taking a moral high ground, the problem is systemic and I don't accuse anyone in particular. Rich people, not above the law ? Yeah... I won't answer that because I don't believe it to be true, but I cannot formally prove it.

Oh we do have solutions but you wouldn't like those. Carbon taxes, unlawful to eat meat besides on weekends, mandatory carbon offset of long-distance and/or plane trips, unlawful to advertise in public spaces and I have a whole lot more for you - but they will never get implemented ;)
