Traveling for your daily commute can be damaging to the environement if you drive a car, so why not bike, take transit, or just carpool? Ideas like this can make a world of difference when done en masse. Fortunately someone has gone and made a list of 31 green travel tips to ensure that we do less damage from our travels.
From the section on airplane travel:
24. Combine work and play: If you just have to attend a meeting somewhere overseas, why not book a few days off after the meeting and stay there for a week or so? That way you get the best of both worlds and you don’t have to fly as much, which will massively reduce your carbon footprint.
25. Carbon offset flights: Many airlines are waking up to carbon offsetting and passing some of the expense on to their passengers. If you are so inclined (and can afford it) you can pay a little extra for your flight and the airline will take your extra money and invest it directly into planting trees. Companies such as Treeflights exist in the UK to do just that, planting trees in Wales and Peru.
26. Travelling to the airport: Most hub and regional airports have good public transport links, which means you can catch the bus or train instead of driving to the airport and adding to your carbon footprint even more.
