Per region CO2 emissions don't matter, CO2 is a largely non-reactive gas, which is rapidly mixed throughout the entire troposphere in less than a year.
It's the total CO2 amount in atmosphere that determines radiative forcing.
The IPCC summarized the current scientific consensus about radiative forcing changes as follows: "Human-caused radiative forcing of 2.72 W/m2 in 2019 relative to 1750 has warmed the climate system. This warming is mainly due to increased GHG concentrations, partly reduced by cooling due to increased aerosol concentrations"
