I'm not quite sure what category to put Lavoisier, HR Nichols et al under. Front groups? They're not quite turfy enough to be astroturf, & not quite thinking enough to be think-tanks. And where would the UIC go - they (supposedly) dont do much in the way of lobbying... maybe there should be one for 'corporate funded research centres', although they dont do much in the way of research either.
As for Lavoisier etc -- there's a section on the http://www.sourcewatch.org/index.php?title=Climate_change_sceptics#Organizational_Skeptics page for organisations that are Kyoto sceptics.
