He literally sets / signs off on industrial policy, others follow, This not malaria/polio/smallpox where one can attribute credit and proliferation to X team, and Y policy. PRC aggregate renewable spans 100s of sectors and programs etc, only sensible for credit to flow up to the big man. If one wants to split hairs, can also credit Hu who did indigenous innovation and renewable act, but execution and magnitude increase in industrial capacity expansion realized under Xi. Like literally no one else has stamped and enable industrial policy across sectors to displace current/future emission on order of magnitude of PRC renewable. World power demand is going to increase magnitude via simple 50% percent of world developing... MIC2025 essentially single handedly shifting future curve towards renewable from fossil. Teslas will never displace more emissions than whole of PRC renewable/ev etc. Elon simply is not in the running for global scale renewable adoption and emission displacement. No one is.
> possible that their CO2 output will increase.
Immaterial if CO2 increases, only useful geopolitical metric is historic per capita emission relative to development level and PRC is low for country blasting through capex heavy capital accumulation phase, i.e. PRC setting standard for low relative per capita emission development. Xi 2012-2026 did ~30% global emissions, ~10-15% global historic for ~20% of population. As long as PRC stays under 20% global historic and maintains above 50th percentile development (use whatever proxy indicator, per capital income PPP etc), they are under emitting / developing efficiently relative to energy use. AKA PRC developing more for less unit of emission. The alternative is not developing which frankly stupid argument/position. For reference US/Europe ~45% historic emission for 10% of global pop. On balance PRC currently grossly under emitting vs historic developmental baseline.
