How Your Travel Choice Impacts the Planet

Emission Calculation Methodology

Carbon dioxide emissions from travel result from multiple sources beyond fuel combustion. Accurate assessment requires understanding both direct operational emissions and lifecycle impacts of transportation infrastructure.

Travel emissions include vehicle operation, fuel production, infrastructure amortization, and accommodation energy consumption. Total impact varies significantly based on occupancy rates, vehicle efficiency, and trip duration.

Primary Emission Sources

• Direct fuel combustion during transport
• Fuel extraction and refining (well-to-wheel emissions)
• Vehicle manufacturing amortized over operational life
• Infrastructure maintenance (airports, roads, accommodation)
• Auxiliary services (ground transport, facilities)

Variables Affecting Carbon Footprint

Vehicle Efficiency by Category

Occupancy Impact Multipliers

• Solo travel: 100% emissions per person
• Two passengers: 50% emissions per person
• Four passengers: 25% emissions per person

Maximizing vehicle occupancy is the single most effective emission reduction strategy across all transport modes.

Trip Distance Efficiency Thresholds

• Short trips (< 500km): Aviation competitive on total emissions
• Medium trips (500-2000km): Ground transport advantage
• Long trips (> 2000km): Accommodation type becomes dominant factor

Accommodation Carbon Intensity

High-Impact Accommodation

• Luxury hotels: 25-40 kg CO₂ per night
• Resort complexes: 30-50 kg CO₂ per night (pools, spas, climate control)
• Business hotels: 15-25 kg CO₂ per night

Medium-Impact Accommodation

• Standard hotels: 10-20 kg CO₂ per night
• Guesthouses/B&Bs: 8-15 kg CO₂ per night
• Hostels: 5-12 kg CO₂ per night

Low-Impact Accommodation

• Camping with facilities: 2-5 kg CO₂ per night
• Wild camping/rooftop tents: 1-3 kg CO₂ per night
• Eco-certified accommodations: 3-8 kg CO₂ per night

Emission Reduction Strategies

Vehicle Selection

• Choose most fuel-efficient vehicle for passenger count
• Avoid oversized vehicles for terrain requirements
• Consider hybrid/electric options where charging infrastructure exists

Route Optimization

• Plan direct routes to minimize total distance
• Combine multiple destinations efficiently
• Avoid high-traffic areas that reduce fuel efficiency

Accommodation Choices

• Prioritize low-infrastructure camping over energy-intensive hotels
• Select eco-certified accommodations when indoor lodging required
• Extend stays to reduce transportation frequency

Trip Planning

• Maximize passenger count through shared travel
• Choose destinations accessible by efficient transport modes
• Balance trip frequency with emission impact per journey

Carbon Offset Considerations

Quality carbon offsets can neutralize unavoidable emissions, but effectiveness varies significantly by program standards.

Verified Offset Programs

• Gold Standard: Internationally recognized certification
• Verified Carbon Standard (VCS): Rigorous project verification
• Climate Action Reserve: North American standards
• Plan Vivo: Community-focused sustainable development

Offset Costs by Travel Mode

• Brussels-Biarritz rooftop tent: €5-8 to offset
• Brussels-Biarritz car + hotel: €8-12 to offset
• Brussels-Biarritz flights: €15-25 to offset

Future Technology Impact

Electric Vehicle Adoption

Current electric vehicles reduce transport emissions by 60-80% in regions with renewable electricity. However, charging infrastructure limitations restrict long-distance touring capability.

Sustainable Aviation Fuels

Next-generation biofuels could reduce aviation emissions by 50-80%, but remain cost-prohibitive and production-limited for widespread adoption.

Efficiency Improvements

Vehicle efficiency continues improving at 2-3% annually, with new models producing significantly lower emissions than previous generations.
