If you don't want to give up long-haul travel but are concerned about the carbon wake left by airplanes, why not cut back on your emissions by traveling overland?
Ozbus, a company offering a long-distance overland service from London to Sydney, began operations last month. The 12-week trip across the world includes activities in 20 different countries and every terrain from deserts to rain forests.
The itinerary includes stops in Iran, Pakistan, Myanmar and Malaysia, although the schedule may change because of political and environmental conditions. Geared toward backpackers (half the nights are spent camping), the trip involves one short flight, from East Timor to Darwin, although Mark Creasey, the company's founder, said he was trying to find space for his group aboard a ship.
The next trip leaves on Sept. 17 and arrives in Sydney on Dec. 9. The cost is £3,750 a person, about $7,350, at $1.99 to the pound. Information: www.oz-bus.com.
Intrepid Travel is an Australian tourism company that is offering a 130-day trip from Singapore to Paris called To the End of the Earth and Back.

The trip's price starts at $12,410 a person (plus $1,300 in local payments); www.intrepidtravel.com/endearth.
