The average American emits 16 tons CO2/year. Global average is 4 tons. To meet climate goals, we need to reach ~2 tons per person. Here's how.
CALCULATE YOUR FOOTPRINT
Best calculators:
CoolClimate Calculator (UC Berkeley): coolclimate.org/calculator EPA Carbon Footprint Calculator: epa.gov/carbon-footprint-calculator WWF Footprint Calculator: footprint.wwf.org.uk Carbon Footprint Calculator: carbonfootprint.com
What they measure: Transportation, home energy, food, shopping, services
AVERAGE EMISSIONS BREAKDOWN
Transportation: 29% (cars, flights, public transit) Home energy: 27% (heating, cooling, electricity) Food: 23% (agriculture, processing, transport) Goods/services: 21% (shopping, entertainment, healthcare)
TRANSPORTATION - BIGGEST IMPACT
Driving less: Walk/bike short trips (0 emissions) Public transit (45% less than driving alone) Carpool (50% less per person) Remote work (eliminate commute)
Vehicle choices: EVs: 50-70% less emissions than gas cars over lifetime Hybrids: 30-40% less emissions Efficient gas car: 20-30% less than average Keep car longer (manufacturing emissions amortized)
Flying: Biggest personal carbon source for frequent flyers One transatlantic flight: ~1-2 tons CO2 Reduce flights, take train when possible, choose direct flights (takeoff/landing most intensive)
HOME ENERGY - QUICK WINS
Immediate actions: LED bulbs (75% less energy than incandescent) Unplug phantom loads (10% energy savings) Adjust thermostat (2°F shift = 5% savings) Cold water laundry (90% less energy than hot) Line dry clothes when possible
Medium-term: Smart thermostat ($100, saves 10-15%) Insulation and weatherstripping Energy Star appliances Heat pump (replaces furnace + AC, 50% savings)
Long-term: Rooftop solar (ROI 5-10 years, $0 bills after) Solar+battery (energy independence) Full home electrification Deep energy retrofit
RENEWABLE ENERGY OPTIONS
Own your roof: Solar panels ($15K-$25K, 30% federal tax credit) Rent: Community solar (subscribe to local solar farm, 5-15% bill savings) Can't install: Green power plans (utility offers renewable energy)
FOOD - OFTEN OVERLOOKED
Biggest impact: Reduce beef (1kg beef = 27kg CO2, equivalent to 100+ miles driving) Reduce lamb (1kg = 24kg CO2) Moderate dairy and pork Increase plant proteins (1kg lentils = 1kg CO2)
Other food actions: Buy local and seasonal (less transport) Reduce food waste (1/3 of food wasted globally) Compost organic waste Eat less processed food (high energy input)
Plant-based impact: Vegan diet: 50-75% less food emissions Vegetarian: 40-50% less Reducetarian (less meat): 20-30% less
SHOPPING AND CONSUMPTION
Buy less: Biggest impact is not buying in first place Ask: Do I need this? Will I use it long-term?
Buy better: Quality over quantity (lasts longer) Secondhand first (thrift, eBay, Craigslist) Repair instead of replace
Avoid fast fashion: Clothing industry: 10% of global emissions Average garment worn 7x before disposal Buy fewer, better quality clothes Support sustainable brands (Patagonia, Allbirds, Reformation)
OFFSETTING (Last Resort)
After reducing emissions, consider offsets for unavoidable emissions
Quality offset programs: Verified Carbon Standard (VCS) Gold Standard Climate Action Reserve
Types of offsets: Renewable energy projects Forest protection/reforestation Methane capture Direct air capture
Offset costs: $10-$30 per ton CO2 typical Annual offset for average American: $160-$480
Caution: Some offsets are greenwashing. Look for additionality (wouldn't happen without funding) and permanence (carbon stays removed).
REDUCTION TARGETS
Immediate (within 6 months): Switch to LED bulbs (0.5 tons/year) Reduce beef consumption (1 ton/year if heavy consumer) Carpool 2 days/week (0.5 tons/year) Total potential: 2+ tons/year
Near-term (1-2 years): Install solar panels (3-4 tons/year) Switch to EV (2-3 tons/year) Go vegetarian (1-2 tons/year) Total potential: 6-9 tons/year

Guides: Project Drawdown: Top 100 climate solutions ranked Citizens' Climate Lobby: Political action guide The Carbon Almanac: Climate solutions encyclopedia
Communities: r/ClimateOffensive r/ClimateActionPlan Local climate action groups
IMPACT COMPARISON
One year of actions: Go car-free: 2.4 tons saved One fewer transatlantic flight: 1.6 tons Install solar: 3.5 tons Go vegan: 1.5 tons Switch to green energy: 1.5 tons
DISCUSSION
What's your current carbon footprint? What reduction strategies have worked for you? What's the biggest challenge in reducing emissions? Should we focus more on individual or systemic change?
