I have a "green" solution for the planet...
How about we gradually reduce the human population back to 2 billion (no need to kill people or start a war - just let it happen over the course of 100 years by limiting the number of children).
Abolish interest on money - this is the reason economies have to "grow". It is actually a pyramid scheme on a finite size planet. Doomed to fail. Get rid of interest rates and there is no longer a need to grow the economy.
Educate people so that they behave rational. People's retirement plan must consist in saving the exact amount of money you will need once you stop work. The current generational systems are, again, a pyramid scheme!
Make products have a mandatory life expectancy of at least 10 years. Why do we need to change car, TV, mobile phone, etc. every two to four years? Only for the economy to grow. This causes so much waste!
Eat less!
With these simple points, we will meet all climate goals, while maintaing a high living standard.
All the hype with electric cars, hydrogen, etc. is bullshit. It won't be enough for soon to become ten billion people and it does little to nothing to "save" the earth.
