Your Personal CO2 Budget — 1.5°C Truth

Based on IPCC AR6 (2022) and Our World in Data 2024. The 1.5°C-compatible per-capita budget is ~31 tCO2 total across remaining decades, or ~1-2 t/year. Most developed-world citizens emit 4-15× that. The tool blends your country\'s per-capita baseline with your specific lifestyle (flights, driving, diet, heating).

Frequently Asked Questions

What's the 1.5°C budget?
IPCC AR6 (2022): for a 50% chance of staying under 1.5°C warming, humanity has ~250 GtCO2 left as of 2025. Divided by ~8 billion people = ~31 tons total per person across remaining decades. Spread over 30 years = ~1-2 tons/year. Most developed-country citizens emit 8-15 tons/year currently.
Is my personal footprint really the issue?
It's necessary but not sufficient. ~70% of emissions are tied to personal consumption (housing, transport, food, goods). The other 30% is industrial/government. Both have to fall. Personal action: ~50% reduction is realistic without lifestyle collapse, by targeting flights, meat, big cars, fast fashion.
How much can I really cut?
High-impact moves: Skip 1 long-haul flight = 2-4 tons. Switch from beef to mostly-plant diet = 1-1.5 tons. Sell 1 car / use public transport = 2-3 tons. Switch electricity to green = 1-2 tons. Sum: 5-10 tons/year if you really commit. That gets a typical European to ~3 tons/year — still over Paris but in fighting range.
What about offsets?
Carbon offsets work only if (a) certified high-quality (Gold Standard, Verra), (b) used as last-mile after reductions, not first move. Forestry offsets are mostly broken. Direct air capture is real but expensive (€600-1000/ton). The honest answer: reduce first, offset only what you cannot reduce.
