Frequently Asked Questions
What is a carbon footprint?
A carbon footprint is the total amount of greenhouse gases (primarily CO2) generated by your actions and lifestyle. It includes emissions from transportation, energy use, food consumption, and purchases.
How can I reduce my carbon footprint?
Key ways include: using public transport or biking, reducing air travel, switching to renewable energy, eating less meat, buying less and choosing sustainable products, and improving home energy efficiency.
What is the average carbon footprint?
The global average is about 4 tons CO2 per person per year. However, this varies significantly: US average is ~16 tons, European average is ~7 tons, and some developing countries are below 2 tons.
How many trees does it take to offset my carbon footprint?
One mature tree absorbs approximately 22 kg (48 lbs) of CO2 per year. For an average US carbon footprint of 16 tons, you would need about 730 trees. However, reducing emissions is more effective than offsetting alone.
Which activity has the biggest carbon footprint?
Air travel typically has the highest impact per activity. A single long-haul flight can produce 1-3 tons of CO2. Other major contributors include car commuting (2-5 tons/year), home heating/cooling (1-3 tons/year), and meat consumption (1-3 tons/year).
