We can compare many metrics: CO₂ emissions per capita for different regions, cumulative CO₂ emissions, share of global cumulative CO₂ emissions.

Conclusions would be: it's not that renewables are not helping, it's renewables are not helping enough. We need global emissions tax. The European Carbon Border Adjustment Mechanism (CBAM) is a step in the right direction, but still a very small step because it covers only production of few carbon-intensive goods imported to Europe.
