From accounting to reducing: challenges
Sector characteristics:
• 60% of cement emissions: process emissions
• Long infrastructure life
• Increasing demand … …
Industry emissions reductions with Protocol:
• Sector specific detail
• Benchmarking and target-setting
• Policy framework based on sound data
• Competitive issues, anti-trust
• Using the data
3
Sector specific detail
‘… provide a harmonized methodology for calculating
CO2 emissions, with a view to reporting these emissions
transparently’
‘… addresses all direct and main indirect sources of CO2
emissions related to cement manufacturing, in
absolute and specific or unit-based terms’
Developed and revised with stakeholders

Verification
Item
Proposed requirement
Standard
ISAE3000, ISO 14064-3 and CSI CO2 Protocol
Materiality
Threshold
5% of one or more CO2 KPIs
Level
Limited
Frequency
At least once every two years, assuring data from both
Coverage
Verifiers decide number of sites to be visited and assurance
statements explicitly mention number of sites visited and
corresponding % CO2 emissions covered
Sampling Plan
Deadline
Count plants assured in other schemes (eg EUETS, CDM) as
samples for CSI CO2 assurance, avoiding double verification
Data must be verified and reported:
• Old plants/ new plants/ acquisitions – two years at most
• New CSI members – four years at most
5
Benchmarking, target-setting
Companies set own emissions reductions targets, sharing
learning together
By 2010 (1990 baseline)
• Holcim: 20% reduction in specific CO2 emissions
• Titan: 15% reduction in specific CO2 emissions
• Siam Cement Group: reduction to 670 kg/ton cementitious product
By 2012 (1990 baseline)
• Votorantim: 10% reduction in specific CO2 emissions
• Italcementi: reduction to 690 kg/ton cementitious product
… etc
6
Policy framework based on sound data
• CSI ‘Getting the Numbers Right’
• Aim: obtain current and robust data for CO2 and
energy performance … at global and regional levels
across cement companies worldwide
Provides:
– transparent, verifiable, current data on key drivers of
emissions and performance
– global and regional data: 1990, 2000, 2005, 2006, 2007
2007 data = 891 global cement installations /
31% of global cement production

‘Getting the Numbers Right’
Note: 5 Chinese companies recently joined the CSI; their production volumes and emissions
data are not yet included. Once they are, coverage in China will reach approximately 20% and
global coverage over 40%
8
Competition issues, anti-trust
• Managed by independent 3rd party
• Complies with anti-trust laws
• Participants may only see reports on own individual
company data or aggregated results
• Confidential information on companies or plants is:
– not disclosed
– not accessible
– protected by contractual and data security measures
