The problem here is that many countries are just outsourcing their CO² output. If you move the factory to Asia, the CO² output doesn't show up in your country, but instead in Asia.

Another issue with the charts by the BBC is that they don't show per-capita data but instead the total amount, and the "needed for 1.5°" curve is also not adjusted per-capita but instead adjusted based on what the country is doing so far. So for example, it allows for the USA to have per-capita yearly CO² emissions of ~10t by 2030, while Kenya only gets 0.95t per capita.

Actually, they say Kenya is wildly not on track to reach the 1.5° goal, while even the incredible increase that they are projecting based on the policies curve would only put them up to 2.4t CO² per capita, compared to the 10t CO² per capita that they put as the "USA would be awesome if they managed to reduce to that level".

Almost all European (and many other) countries have set similar goals for 2000, 2020, 2035 and noch 2050, and we are all just breezing by them. On the contrary, the CO2 output has increased since 1990.

Setting goals doesn't matter if there is no plan and no punishment for not keeping it.

The current plan of basically all countries is "let's wait another 20 years and see if some magic technological solution to our problems appear". That's not planning, that's superstition.
