That graph is well below earlier forecasts. Accurate predictions require more than simple extrapolations which 30 years ago suggested exponential growth. Instead CO2 per capita and especially in terms of GDP resulted in a different story.

Add in more kids being born in 1985 than 2025 and per capita numbers matter. https://ourworldindata.org/grapher/number-of-births-per-year
Poor countries are rapidly becoming wealthier which is obviously a good thing. Meanwhile wealthy countries are becoming a lot more efficient with their carbon emissions. Where those lines intersect is what matters in the near term because poor countries aren’t copying 1950’s technology. Skipping power hungry CRT screens and inefficient engines etc just makes economic sense. China emissions spiked as they industrialized but they are currently minimizing their investment in outdated fossil fuel based technologies in favor of solar and EV’s etc.
