Carbon Footprint & Sustainability
Environment — Frequently Asked Questions

A carbon footprint is the total amount of greenhouse gases (expressed as CO₂ equivalent, or CO₂e) emitted directly and indirectly by an individual, organization, or activity. It is measured in metric tons of CO₂e per year. The global average is about 4.7 tons per person; the US average is about 16 tons; the EU average is about 8 tons. The Paris Agreement target requires reducing to about 2 tons per person by 2050.
What are the biggest contributors to an individual's carbon footprint?
For most people in developed countries, the top contributors are: (1) transportation — especially flying and solo car driving (25–40%), (2) home energy — heating, cooling, and electricity (20–35%), (3) food — especially meat and dairy production (15–25%), and (4) consumption — manufactured goods, clothing, and electronics (10–20%). The specific proportions vary by lifestyle and location.

Carbon offsets fund projects that reduce or remove CO₂ from the atmosphere (reforestation, renewable energy, methane capture) to compensate for emissions elsewhere. Quality offsets are verified by standards like Gold Standard, Verra/VCS, or the Clean Development Mechanism. While offsets can be part of a climate strategy, direct emission reductions (flying less, switching to renewable energy) are always preferred over offsetting.

A round-trip economy flight from New York to London produces approximately 1.6–2.0 tons of CO₂ per passenger. Business class produces 2–3× more due to larger seat space. Short-haul flights are less efficient per kilometer due to takeoff/landing cycles. Our carbon calculator includes aviation emissions with class-of-service adjustments.

The most impactful dietary changes are: (1) reducing red meat consumption (beef produces ~27 kg CO₂e per kg vs. ~3 kg for chicken), (2) minimizing food waste (about 30% of all food is wasted globally), (3) choosing seasonal and local produce when possible, and (4) incorporating more plant-based meals. A fully plant-based diet can reduce food-related emissions by up to 50%.
