Emissions factors convert activity data (fuel burned, electricity used) to greenhouse gas emissions. They vary by fuel type, region, year.

ସୂତ୍ର

Emissions = Activity × Emissions Factor

ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |

  1. 1Emissions = Activity × Emissions Factor
  2. 2Gasoline: ~2.3 kg CO₂/liter, electricity: 0.2-0.8 kg CO₂/kWh (regional)
  3. 3Factor varies with grid composition (coal heavy = higher)

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
Drive 1000 km, car uses 5 L/100km, total 50 L fuel
ଫଳ
50 L × 2.3 kg CO₂/L = 115 kg CO₂ emissions
Typical car trip

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

  • Using national average when regional factor available
  • Forgetting to account for upstream emissions

Why do electricity emissions vary by region?

Coal-heavy grids (high factor), nuclear/wind grids (low factor). US average ~0.4, coal region ~0.8 kg CO₂/kWh.

Are lifecycle emissions included?

Basic factors only include combustion. Full lifecycle includes extraction, production, transport.
