After spending 18 months abroad, McMillans were inspired to return home to Scotland with as little environmental impact as possible. En route from Singapore, they journeyed across 14 countries over 85 days, using 22 buses, 14 trains, 11 boats and numerous rickshaws. They enjoyed it so much that they started a website to help others do the same -- flightless travel. Aircrafts currently produce 4% of Europe's CO2 emissions but recent research has found that aircraft emissions have up to 2.7 times more impact on the air than ground emissions due to the delicate nature of the upper atmosphere. While "slow travel" is better for the environment, Tom McMillan feels that is also a great way to engage with the world and "savour the moment."
