Re: GSBN:Cemento (combined responses)



Thanks Mark Ð 

It looks as though the 6-10% figure so often quoted in green architecture
circles for cement manufacturingÕs CO2 contribution may be partially right-
and wrong.

But see a graph at 

<a  target="_blank" href="http://cdiac.esd.ornl.gov/trends/emis/glo.htm";>http://cdiac.esd.ornl.gov/trends/emis/glo.htm</a>

This was in one of the references Mark so kindly put out.  It puts cement
manufacturing contribution at somewhere around  2-3 %  annual global CO2
emissions 

So although cement is one of the major players in the world&#xD5;s pollution, and
certainly in the construction industry&#xD5;s contribution, it looks to me that
although its present contribution may now be nearer 2-3 % of overall annual
global CO2 emissions, its cumulative total effect of all human generated CO2
appears to be nearer 8% &#xD0;  does this look right to anybody else?
