Transportation Carbon Calculator

✈️

Flight Emissions

Assumes round trip (×2)
Uses radiative forcing multiplier ≈1.9 (applied in calculations) for non-CO₂ effects
🚗

Car Emissions

For EVs, includes grid emissions based on your region
🚆

Train & Bus Emissions

Assumes round trip (×2)
Rail typically has 70–85% lower emissions than air travel

How this fits into your planning

Use this calculator to see where emissions come from (flights, car transfers, rail/bus). Next, use Comparisons to choose the best transport option, and Trip Planner to build a lower-carbon itinerary. Later, use Interactive Maps to explore accessibility and trade-offs visually.

🚆 ✈️ Travel Decision Tool

Answer a few questions to find your best travel option

1 Is there a direct train under 2.5 hours?

2 Do I need to work or want to relax?

3 Am I going to islands or northern Spain?

4 Booking last minute on a budget?

5 Carrying lots of luggage?

🚆 RECOMMENDATION: Take the TRAIN

Based on your answers, the train is your best option!

Why train wins:
  • Flights are often banned for short distances
  • Better for work or relaxation
  • Train stations are easier with luggage

✈️ RECOMMENDATION: FLY without second-guessing

Based on your destination, flying is the clear choice!

Why flying wins:
  • Islands and northern Spain are better reached by air
  • Often faster for remote destinations

🔍 RECOMMENDATION: Check BOTH options

For last-minute budget bookings, compare train and flight prices.

What to do:
  • Check budget airlines for last-minute sales
  • Compare with train ticket prices
  • Sometimes flight sales beat last-minute train prices

🤔 RECOMMENDATION: Consider both options

Compare train and flight options based on these factors:

Factors to consider:
  • Environmental impact (train is greener)
  • Total door-to-door travel time
  • Current prices for both options
  • Personal preference for comfort
