Frequently Asked Questions
What is a carbon footprint?
A carbon footprint is the total greenhouse gas emissions caused by an individual, organisation, or activity, expressed in CO2-equivalent tonnes. It includes direct emissions (driving, heating) and indirect emissions (electricity, food production, goods manufacturing).
Is the average US carbon footprint really 14-16 tonnes?
Yes. The US EPA and World Bank data consistently put average American per-capita emissions in the 14-16 tonne range. This is among the highest in the world, driven by high car use, large homes, air conditioning, and animal-heavy diets.
What single action reduces footprint the most?
For most people with cars, eliminating or electrifying car travel and cutting beef consumption have the highest measurable individual impact. Flying less also has a large impact per change. The right action depends on your current habits.
Does individual action matter if corporations emit more?
Both matter. Corporations emit on behalf of consumers - demand drives supply chain emissions. Individual choices signal market preferences, influence social norms, and aggregate to meaningful collective impact. Systemic policy change is also essential and independent action does not replace it.
