Hi Brian, Joe, ENviro Listservers, Thanks, I think I agree that we have the technology to make changes in 20 years, yet not the political ability or will. Too many well established and connected companies is one problem. Usually they will buy up technologies that threaten their base. From my little experience the GCI web site is designed a bit odd and hard to navigate and search. On the GCI site I believe the piece on the Montreal Protocal was in the Correspondence Tab on the far left where Aubrey (not Aud) seems to add current things as they happen. I couldn't find anything on the M.P. after looking long enough this morning. If you get a chance read some of the notes in the Correspondence section. To me it seemed like the most useful portion of this site. http://www.gci.org.uk/ Yours in Engineering, Dave YiEngr, MA/NY DDave
