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-
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
So although cement is one of the major players in the worldÕs pollution, and
certainly in the construction industryÕs 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% Ð does this look right to anybody else?
