Understanding and Reducing Your Carbon Footprint
A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Globally, the average sits closer to 4 tons. To avoid a significant rise in global temperatures, the global average footprint must drop under 2 tons by 2050.
The Global Discrepancy
Developed nations consume vastly more energy per capita than developing nations. Air conditioning, fast fashion, high meat consumption, and frequent air travel are primary drivers of massive individual footprints.
The Impact of Transport
Replacing just 20 miles of driving per week with public transit or biking can eliminate nearly 1,000 pounds of carbon dioxide emissions over the course of a single year.
High Impact Lifestyle Changes
While systemic changes by governments and corporations are essential, individual choices still account for up to 70% of global greenhouse gas emissions. Here are the most effective ways to lower your personal footprint:
- Switch to a Plant-Rich Diet: Meat production, specifically beef and lamb, generates massive amounts of methane and requires huge tracts of deforested land. Adopting a vegetarian diet can reduce your food footprint by half.
- Home Energy Efficiency: Ensure your home is properly insulated. Switch to LED lighting and, if possible, opt-in to a green energy tariff with your utility provider so your electricity comes from wind or solar.
- Fly Less Frequently: A single round-trip transatlantic flight can add up to 2 tons of CO₂ to your footprint—more than the total yearly footprint of an average person in many countries.
