How to Calculate Carbon Tax
What is Carbon Tax?
Carbon tax estimates the cost of greenhouse gas emissions under a price-per-ton-CO₂ policy. It values environmental externalities.
Formula
Carbon tax = emissions (tonnes CO₂e) × tax rate ($/tonne)
Step-by-Step Guide
- 1Carbon tax = emissions (tonnes CO₂e) × tax rate ($/tonne)
- 2Rates vary: $0-200/tonne CO₂e globally, ~$10-60 typical
- 3Encourages emission reduction and clean technology adoption
Worked Examples
Input
Annual emissions 5 tonnes CO₂e, carbon tax $50/tonne
Result
Annual tax $250 (incentivizes reduction)
Makes clean energy attractive
Common Mistakes to Avoid
- ✕Assuming carbon tax alone solves climate change (needs multiple policies)
- ✕Neglecting regressive impact on low-income households
