We do not seem to be able to limit the global warming to less than 2 degrees. Many nations have legislated or promised ambitous goals to reach net-zero, but during 2022 and 2023 we saw no radical changes that would make us believe that we are ever going to fulfill the ambitious goals, until 2030, 2040 or 2050 which are often the years we have promised to reach net-zero in different sectors and nations. We continue to live like there was no tomorrow, or in scientific terms, "business as usual". Even if we according to definitions reach net-zero in various sectors, this is often accomplished without taking the full life-cycle into account, meaning it is not net-zero in reality.
Hence, our current socioeconomic system has a lot of rigidity, that does not allow for radical changes to be implemented. It seems in other words, that we need to change the economic system in the world to be able to mitigate climate change. But, when I read different articles, books, etc, I have never found any suggestion by economic experts how this economic system could look like. I only heard in vague terms that we need to go away from today's system and have a circular economy. But, no one is able to explain how the foundation of a new economic system could look like and what it means in simple terms. Maybe there are no systems that could repalce today's system. So, this is what I'm asking for: How could an economy work (explained for a non-economic expert) that would save the earth?
