Degrowth

Actually not at all. 12 Trillion over 7 years means 1.7Trillion added to global annual GDP. The global economy has a GDP of a bit over 100 Trillion. So we are talking adding 1.7% growth and then stagnation. For the most part global GDP has grown by about 3%. So we are talking a low year in terms of GDP growth and then no growth at all.

As for the UN SDG part of them is to meet the most basic material needs of everybody. When poor people get money, they spend it. That is just logical, when you need food and have money, buying food makes perfect sense. At the same time better education also helps the economy a lot. Long term that would stop global population growth a lot faster and be a net positive the everybody. The other part is that renewables require a lot of investment as well, which also naturally grows GDP.
