It seems that hardly a week goes by without the IPC advertising some 
meeting, conference, exhibition or other event (webcasts excluded). Then 
there are others sponsored by other organisations.

These most frequently involve travelling and lodging in hotels, neither 
of which are without a severe impact on the environment. It would be an 
  interesting calculation to work out the no. of kg of CO2 emitted for 
attendees of these events just to be there.

The figure must average in the hundreds of kg/delegate, if not more. Is 
there any way to reduce this, e.g., more Internet conferences, seminars 
equipment demos, one-on-one discussions etc???

Just a thought with oil at $150/bbl to spice the discussion.
