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"
Regional emissions do matter for the conclusions you draw.
All high-income countries already trend down in emissions.
Global emissions are rising because poorer countries that were basically almost "no emission"/capita in the past are still catching up (but that catch-up is less steep than in the past because green energy is available from the get-go).
Conclusions would be: Emission reductions in rich countries need to be aaccelerated, and helping poor countries peak at a lower level would probably be prudent (but good luck selling such policies to alt-right voters).
"Renewable are not helping" is not a sensible conclusion.
