Thanks for your replies. As I see it, focus has been on individual actions and individual responsibility which is important but the solutions are primarily on the systemic structural level. Two examples of what this means and how individuals can contribute to solutions on the structural level.
Demands on production
The European Union has regulated vacuum cleaners demanding that producers build vacuum cleaners that use less than 800 watts. Before this regulation 2000 watts was normal. Today they all use 800 watts.
So we could write new market rules and promote them.
Clear information about pollution levels and emitters
The Public doesn't have access to clear and user-friendly data about pollution levels and the companies that emit. Right now people are pretty confused which inhibits action and help those who wants to continue with business as usual.
For example, coal power plants. The data exists but needs to be more accessible. What plants exist in my country? My city? How much energy does it produce and needs to be replaced with renewables? Wikipedia lists the largest coal power stations in the world which is a start but the information should be even more accessible, shaped to help people act. When we have specific targets we can demand that politicians act.
