Gilbert reference follows.

When you complete your report why don't we just place it in the @ccess or
WTP&P library (along with anything else of yours that you think might be of
use to people.

8.  SPOTLIGHT ON AVIATION IMPACTS
The environmental impacts of aviation are receiving increasing
attention. The IGFR Open Research Program Research Group
<20. transport> (contact: igfr at i...) recently drew our
attention to Issue No. 3 of the Sustainable Transportation
Monitor which focuses on aviation. It states that  '...of all
transport modes, aviation is the least environmentally
sustainable at present, and shows the least promise of becoming
sustainable.' At currently typical vehicle occupancies and fuel
efficiencies, air travel fuel use per person is similar to the
rate for car travel. However, the climate change impact of air
travel is estimated at about three times the rate of car travel
- primarily because engine emissions at altitudes of 10-11 km
appear to have a more potent greenhouse effect than the same
emissions at sea level. For example, high altitudes enhance the
formation and greenhouse potency of ozone from NOx emissions.
Global air travel is growing at about 5 percent annually. The
