‘Getting the Numbers Right’: Beyond the Inventory in the
Cement Industry
23 March 2010, Washington, USACaroline Twigg
World Business Council for Sustainable Development (WBCSD)
WBCSD Cement Sustainability (CSI)23 member companies 100 countries~40% global production CEOs sign CSI Charter

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
From accounting to reducing: challenges
Sector characteristics:• 60% of cement emissions: process emissions • Long infrastructure life • Increasing demand … …
4
‘… 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
Sector specific detail
5
VerificationItem 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
CoverageVerifiers decide number of sites to be visited and assurance statements explicitly mention number of sites visited and corresponding % CO2 emissions covered
Sampling PlanCount plants assured in other schemes (eg EUETS, CDM) as samples for CSI CO2 assurance, avoiding double verification
DeadlineData must be verified and reported:• Old plants/ new plants/ acquisitions – two years at most• New CSI members – four years at most
6
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
Benchmarking, target-setting

• 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
Policy framework based on sound data

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%
