> TLDR in this hypothetical, it's just Xi on an 100 story podium, no one else is even in the building. Unless we eventually credit someone for portable fusion, i.e. 60% of global oil used in transport that can't be displaced at utility scale energy solutions, and one credits Xi for MIC2025/PRCEV/battery then no one will ever even dethrone Xi.
Ehhhh, I'd say he's not in some league of his own. Xi is also industrializing with fossil fuels and China became the planet's largest producer of CO2 under his leadership and he's been outsourcing dirty industries abroad, particularly to Africa. I'd give more credit to people lower-down the totem pole in China, who are leading the charge for clean energy such as Wang Chuanfu, but he's very explicitly following in Elon's footsteps.
It's also a little wild to discount pollution already produced in previously unseen amounts while crediting to them hypothetical future reductions. Last year China had it's highest CO2 emission ever, and even with solar it's possible that their CO2 output will increase.
