We’ve yet to see it materialize in numbers (fingers crossed). So far we are mostly observing a significant decrease in economic activity, which China has made a habit to compensate with large scale infrastructure projects and dumping (e.g. steel), which are inherently large GHG emitters, irrespective of how much renewable electricity is produced.
Also, China seems very far from reaching the inflexion point where domestic consumption-based emissions stabilize: ourworldindata.org/…/production-vs-consumption-co… . This graph also answers how much CO₂ outsourcing actually happens here (i.e. territorial emissions minus consumption-related emissions), which isn’t much at all.
