  • 2025 Target: 95 g CO2/km fleet average for new cars
  • 2030 Target: 37.5% reduction from 2021 levels
  • Classification: Based on WLTP (Worldwide harmonized Light vehicles Test Procedure)
  • Penalties: €95 per g/km excess over target per vehicle
🌿 Emission Reduction Strategies

🚗 Vehicle Choice Impact

  • Electric Vehicles: 0 g/km direct emissions (90%+ reduction)
  • Hybrid Vehicles: 30-50% reduction vs conventional cars
  • Smaller Engines: 1.0L vs 2.0L can save 30-40% emissions
  • Diesel vs Petrol: 15-20% lower CO2 (but higher NOx/particles)
  • Manual vs Automatic: Manual typically 5-10% more efficient

🛣️ Driving Behavior (20-40% Impact)

  • Eco-driving: Smooth acceleration/braking saves 10-25%
  • Speed Management: 80 km/h vs 120 km/h saves ~25%
  • Cruise Control: 5-10% savings on highways
  • Route Planning: Avoid traffic jams and hills
  • Gear Selection: Higher gears = lower RPM = less fuel

🔧 Vehicle Maintenance (5-15% Impact)

  • Tire Pressure: Under-inflation increases consumption by 5%
  • Regular Service: Clean air filter, oil changes
  • Weight Reduction: Remove unnecessary items (100kg = +5%)
  • Aerodynamics: Remove roof boxes when not needed
  • Air Conditioning: Use wisely (can increase consumption 10-20%)

🚌 Alternative Transportation

Transport Mode CO2 per km per person Reduction vs Car
Walking/Cycling 0 g 100%
Electric Bus 20-40 g 80-90%
Diesel Bus 40-80 g 60-80%
Electric Train 15-40 g 80-95%
Diesel Train 30-60 g 70-85%
Car (Average) 150-200 g Baseline
Motorcycle 80-120 g 40-50%
Domestic Flight 200-300 g -50% to -100%

📊 Quick Reduction Checklist

  • ✅ Immediate (0% cost): Eco-driving, route planning, speed limits
  • ✅ Low cost: Tire pressure, remove weight, regular maintenance
  • ✅ Medium cost: Efficient tires, aerodynamic improvements
  • ✅ High cost: Hybrid/electric vehicle, public transport season ticket
  • ✅ Lifestyle: Combine trips, work from home, car sharing
📚 Emission Calculation Guide

🎯 What are Vehicle Emissions?

Vehicle emissions are pollutants released from motor vehicles, primarily CO2 (carbon dioxide), which contributes to climate change. This calculator focuses on CO2 emissions based on fuel consumption and driving patterns.

🔬 Calculation Formulas

  • CO2 from Petrol: Fuel (L) × 2.31 kg CO2/L
  • CO2 from Diesel: Fuel (L) × 2.65 kg CO2/L
  • CO2 from LPG: Fuel (L) × 1.62 kg CO2/L
  • CO2 from CNG: Fuel (kg) × 2.75 kg CO2/kg
  • Fuel from L/100km: (Distance × Consumption) / 100
  • Fuel from MPG: Distance / (MPG × 4.546)

🌍 Emission Factors by Fuel Type

  • Petrol/Gasoline: 2.31 kg CO2 per liter
  • Diesel: 2.65 kg CO2 per liter (+15% vs petrol)
  • LPG (Liquid Petroleum Gas): 1.62 kg CO2 per liter (-30% vs petrol)
  • CNG (Compressed Natural Gas): 2.75 kg CO2 per kg (-20% vs petrol)
  • Biofuels: Vary by source, typically 20-80% lower

📏 Understanding Different Units

  • L/100km: Liters per 100 kilometers (metric standard)
  • MPG (US): Miles per gallon (US gallon = 3.785L)
  • MPG (UK): Miles per gallon (Imperial gallon = 4.546L)
  • km/L: Kilometers per liter (inverse of L/100km)
  • g/km: Grams of CO2 per kilometer (standard measurement)

⚠️ Factors Affecting Real-World Emissions

  • Driving Conditions: City vs highway (city uses 20-40% more)
  • Weather: Cold weather increases consumption by 10-25%
  • Traffic: Stop-start traffic can double consumption
  • Vehicle Load: Passengers and cargo increase emissions
  • Vehicle Age: Older vehicles typically less efficient
  • Maintenance: Poor maintenance can increase emissions 20%+

🌿 Environmental Context

  • Tree Offset: 1 tree absorbs ~22 kg CO2/year
  • Global Context: Transportation = 16% of global CO2 emissions
  • Personal Impact: Average car emits 4-5 tons CO2/year
  • Target: Paris Agreement aims for carbon neutrality by 2050
  • Progress: New car emissions down 25% since 2000

🔍 Calculator Limitations

  • Based on direct combustion emissions only (not lifecycle)
  • Uses average emission factors (actual may vary ±10%)
  • Doesn't include manufacturing or fuel production emissions
  • Real-world consumption often 15-25% higher than official figures
  • Electric vehicle emissions depend on electricity grid mix

💡 Using This Calculator Effectively

  • Use manufacturer fuel consumption figures for accuracy
  • Add 15-20% to official figures for real-world conditions
  • Calculate both individual trips and annual totals
  • Compare different vehicle options before purchasing
  • Track your emissions over time to see improvements
  • Use results to justify eco-friendly transportation choices
