Vote political parties into power that put a price on emissions and honestly work on reducing it.
The big problem is that this is not gonna be free. When fossils are used, it's obviously because they are the most economical option. As soon as you price in actual externalities (=> climate change), energy is going to get more expensive, and people don't like this. Almost everyone claims to be concerned about climate change, but a lot of people are neither willing to pay more for gas or power, nor do they want to risk making local industry less competitive.
The sad truth is that almost any cost for environmental sustainability/emission reduction is already too much for a lot of people.
If there are no parties mainly concerned with climate sustainability, then that is very likely because voters are not sufficiently interested in such platforms, and are more receptive to messages like "will fight immigrants", "will fight use of incorrect pronouns" or "will prevent trans-women from fighting in womens MMA".
Speaking for the US: climate sustainability (as main focus) was up for election 25 years ago, and about half the nation did not even bother voting, so it seems unsurprising to me that focus has shifted away from this issue (and fair to blame voters for that).
