evaluation of co2 emissions reduction strategies in the iranian cement industry

portland  cement,  as  the  main  constituent  of  conventional  concrete,  is  the  most  widely  used  cementitious material in the construction industry. but portland cement production has major environmental disadvantages, including  high  energy  consumption  and  carbon  dioxide  (co2)  emissions.  so  the  production  of  portland cement  is  accounted  for  7  to  10%  of  global  co2  emissions.

considering  the  amount  of  portland  cement production and co2 emissions in iran, it can be concluded that iran is facing environmental problems caused by cement production. hence, various  co2 emissions mitigation strategies of the iranian cement industry have been evaluated in this study.

this research work applied analytical hierarchy process (ahp) method to evaluate  and  prioritize  mitigation  strategies. the  obtained  results  showed  that  among  the  16  strategies studied,  clinker  substitution  (blended  cement)  and production  of  low  carbon  cement  such  as  geopolymer cement were recognized as the most important strategies to reduce co2 emissions in the iranian  cement industry.
