Rough Guide to Staying Put
While aviation currently only accounts for about 2 percent of total greenhouse gas emissions, it is the fastest growing source (expected to roughly double by 2025), and one not accounted for in the Kyoto treaty. Moreover, airplane emissions have a greater warming effect, pound for pound, than do land-based emissions, as they occur at altitude.
Rough Guide now publishes a Guide to Climate Change, authored by a staff writer from NCAR -- the National Center for Atmospheric Research in Boulder, Colorado. The company urges travelers to fly less and stay longer while also offsetting emissions.
