I think climate activists would just be better off doing what everyone else does - lobbying. Identify politicians who represent areas who would benefit from pollution controls, or green investment or whatever and push the message. Performative acts in front of cameras might feel good but it’s a blunt tool to change policy. Some protestors such as “just stop oil” campaigners are so stupid that they actually help the causes they supposedly oppose.
No change doesn’t happen by asking nicely, but I think some joined up thinking by these groups would get them further than performative protesting and getting arrested. If you want change then you lobby politicians on the positive benefits of change, and businesses on the potential profits to be had from implementing it.
