If you want to think about lifestyle (what is a good thing to do) a more helpful question might be: What is the amount of longterm sustainable carbon emissions, and how can we reach it collectively?

@malte

The numbers aren't useful anymore, because we are too far gone for 1.5. And the number alone always has said less than the assumptions its calculation is based on and the modeled possible passways to reach it, see methods in IPCC reports.

If you must know a number, whatever the assumptions, look it up at global carbon budget:

„The remaining carbon budget to limit global warming to 1.5°C is virtually exhausted. With a warming of the planet attributed to human activities of 1.36°C in 2024, the remaining budget for 1.5°C is 170 GtCO2, equivalent to 4 years at the 2025 emissions levels.“ (2025 key messages)

Nowadays 1,5 is only mentioned together with overshoot. So you'd better prepare to have negative personal emissions. Or shed some delusions.
