Frequently Asked Questions
What is a carbon footprint?
A carbon footprint is the total amount of greenhouse gases (primarily CO2) generated by your actions, measured in metric tons per year. It includes direct emissions (driving, flying) and indirect ones (food production, energy generation). The concept helps individuals and organizations understand their climate impact.
What is the average US carbon footprint?
The average American produces about 16 metric tons of CO2 per year — one of the highest per-capita rates in the world. The global average is about 4 tons. To limit warming to 1.5°C, scientists estimate we need to reach 2 tons per person by 2050. Transportation and food are the two largest personal sources.
How can I reduce my carbon footprint?
The highest-impact changes are: switching to an electric or hybrid vehicle (saves 1–4 tons/yr), reducing flying (one round-trip flight = 0.9 tons), eating less meat especially beef (saves up to 0.5–1.5 tons/yr), switching to renewable electricity, and improving home insulation. Individual action matters, but systemic change amplifies it.
