Human civilization has huge momentum. It took us 70 years of the Great Acceleration via super cheap, super dense, Carbon fuels to grow so big as to get into this complicated mess. We are not going to get out of it in 5 or 10 years. Many infrastructure investments have life cycles of 60-100 years. It is good to start moving away from big pipeline expansions, new cole plants, ect, now. But to pick a date out of a hat and demand that the world be at net zero by 2025, as Extinction Rebellion has done, or in 12 years, as the Green New Deal has done, is clearly pragmatically unattainable without precipitating the complete collapse that they are rallying against. These equally "fairy tale" dates only serve to further alienate people that are still unaware that anything about a growth based social system needs to change.
