I agree with most of what you say Kornelija, the main environmental problem it notcarbon dioxide but consulerism and the throwaway society. And the answer is simply personal responsibility.
One of my grandma's always said "buy cheap, buy twice," yet it takes just as much energy, water, agricultural products, chemicals etc. to make a £5 t shirt as to make a £15 t shirt.
But I'm still wearing the £15 t shirts I bought 7 or 8 years ago, the £5 t shirts were only fit for polishing the car after two years.
Apply that philosophy across the board and emissions will come down
The one thing climate activists are always pushing that annoys me is recycling. It very often requires more energy to recycle than to make new and the recycling industry produces mountains of toxic shite (and just wait til we start recycling Li - ion batters for EVs in large m=numbers.
But then I'm sure EVs will never catch on. An ad campaign for a new small family car, the Corsa, tells me it will get me 209 miles on a single charge. Fine, but I can drive my 20 year old Honda Accord ES 209 miles in the time it takes to charge the Corsa without breaking any speed limits (I would break speed limits of course, but that's a matter of principle.)
We must not be blinded to the practicalities by hype.
BTW I'm so old that when I was a kid we had resusable glass bottles for milk, fizzy drinks etc. It surely can't be beyond the capabilities og modern science to create resusable plastic containers.
