How should you get to your destination? Via car, train, plane, bus? A lot will depend on road conditions, the type of car, how far you're traveling, and how many passengers are involved.
Airplanes emit more CO2 than buses, trains, or cars, but they carry more passengers and make traveling longer distances feasible.
Trains pollute more than cars, but they too carry more passengers.
On the other hand, the materials that go into road construction aren't green at all, so even if you're traveling via fuel efficient car, there are other variables to consider. Likewise with buses.
So, what's the most eco-friendly way to travel? Sadly, there is no right answer. The best we can do is continue to improve our technology, so that green travel will one day be a reality.
