I am hoping for something which might have similar effects: that the EU will get its act together first and implement a carbon taxation scheme, imposing tariffs on imports from countries that do not implement a carbon tax. The US, unfortunately, seems to be in denial of the climate crisis. I wonder if in 30 years we will be putting todays climate deniers in courts (like the Nuremberg trials) for crimes against humanity.
