Isn’t it true that once a car is built, it’s basically better for the environment to drive it until its wheels fall off instead of scrapping it
In terms of global warming; maybe. It depends on many factors when looking at a specific case. Another commenter already put some numbers together.

Brother, with some luck a nuclear plant is in construction stage after those 20 years
