Our Methodology: How it works.

Calculations for the self-drive option consider:

• The distance between your starting city and Dover (if taking the ferry) or Folkestone (for the LeShuttle), and between Calais and your chosen resort.


• Emissions based on the chosen route of channel cross:
• LeShuttle: 2.198706 kg CO2e per passenger
• Ferry: 6.4665 kg CO2e per passenger


• Emissions based on car size and fuel type:
• Small car:
• Diesel: 0.139306 kg CO2e per kilometre
• Petrol: 0.140799 kg CO2e per kilometre
• Hybrid: 0.101499 kg CO2e per kilometre
• Battery Electric Vehicle: 0.048228 kg CO2e per kilometre
• Medium car:
• Diesel: 0.167156 kg CO2e per kilometre
• Petrol: 0.178189 kg CO2e per kilometre
• Hybrid: 0.109038 kg CO2e per kilometre
• Battery Electric Vehicle: 0.052666 kg CO2e per kilometre
• Large car:
• Diesel: 0.208586 kg CO2e per kilometre
• Petrol: 0.272239 kg CO2e per kilometre
• Hybrid: 0.152436 kg CO2e per kilometre
• Battery Electric Vehicle: 0.057974 kg CO2e per kilometre

Calculations for the flight option consider:

• The distance between the selected departure airport and Geneva airport (for flights)


• The distance between Geneva airport and the selected resort (for transfers)
