Whether you're hitting the highway for a weekend in Cleveland with Grandma or jetting off for a business trip in London, there's far more to consider than just garden-variety travel dilemmas (like how to keep off unwanted pounds from Grandma's home cooking or how many pairs of shoes you'll need for that two night excursion to the UK).
The travel industry has multiple environmental impacts, including significant greenhouse gas emissions from vehicles, high energy consumption from hotels and resorts, and mountains of trash from drinks and snack foods bought en route. These concerns are likely to intensify along with the industry’s growth. In 2004, more than 600 million US passengers boarded an airplane to attend a business meeting or take a vacation. By 2010, that number is expected to grow to more than 1 billion.
