2 The Cement Sustainability Initiative (CSI) Edvaldo Araújo Rabelo (Votorantim co-chair of CSI) FICEM XXVIII Technical Congress Sao Paulo, 5 September 2011

3 About the WBCSD The World Business Council for Sustainable Development (WBCSD) is a global CEO-led coalition of some 200 international companies, from 35 countries and 22 sectors, with a shared commitment to sustainable development. Collectively, members represent an estimated: 15 million employees 7 USD trillion annual revenues 5 USD trillion market capitalization (Source: Observatoire de la Finance, Geneva, December 2009) 3

4 Cement Sustainability Initiative 23 member companies One third global cement production Two thirds outside of China 4

5 From study to action Independent Study Planning Action Individual implementation Joint projects + Communication and outreach All reports available on the CSI website, 5

6 CSI Charter All CSI members have signed the CSI Charter It summarizes individual member actions included in the Agenda for Action Companies joining the CSI agree to implement these actions within 4 years of joining 6

7 CSI Work program Future work program Early Work Identifying impacts and minimizing them CO 2, NO x, SO x, micro-pollutant emissions, land use, safety Defining metrics key performance indicators Sustainable use of Construction Materials Impacts on biodiversity Recent Work Public reporting Contributing to public policy International outreach India, China, South America 7

9 CSI and climate change 9

10 CO 2 emissions 5+% of manmade CO 2 emissions come from cement production. Cement is on the radar of all policy makers around the world. Mitigation policies will impact cement production. Carbon costs will be a major production cost in the future. All models (IEA, CSI, McKinsey, others) identify the same 4 levers for CO 2 Control Energy efficiency Alternative Fuels Clinker substitution Carbon capture and storage 10

11 CSI work Five key elements CO 2 Protocol accounting and reporting Global CO 2 and Energy Database Cement Technology Roadmap with International Energy Agency (IEA) Global Climate Policy Analysis Sectoral Approach New CDM methodology, based on standardized baselines (not approved) 11

12 CSI Global CO 2 and Energy Database Getting the Numbers Right (GNR) 12

13 What is the GNR database? The GNR database is : An independently-managed database of CO 2 and energy performance information on the global cement industry. The possibility for all participating companies and interested stakeholders to get access to standard web-based reports. Reflecting their own performance Positioning their performance with regards to the sector s average (worldwide or by region) Within strict confidentiality guidelines. 13

14 GNR database the objective The objective of the GNR database is to deliver : Uniform (based on the agreed GHG protocol), accurate and verified data so that the industry can understand its own current and future performance potential. Key drivers of emissions and performance are also included. policy makers can get access to current performance data to aid their analysis and decisions. 14

15 Confidentiality and anti-trust issues The database complies with anti-trust laws and is managed by an independent third party service provider. Individual participants may only see reports based on their individual company data or aggregated results. Confidential information on individual companies or plants is not disclosed, nor made accessible, and is protected by contractual and data security measures. 15

16 The interests of joining Joining the GNR reporting process provides access to state-of-the-art data and analysis of the cement industry s global and regional performance, allows participants to benchmark their own performance, track their emissions inventories, and develop sound, data-based responses to company and regional climate management issues. Joining is possible directly through CSI (by becoming a CSI member) of through regional trade associations (CEMBUREAU, FICEM ) 16

17 GNR coverage Getting the Numbers Right (GNR) Representative statistical information on the energy and CO 2 performance of clinker and cement production, worldwide and regionally, to serve the needs of internal and external stakeholders. Coverage (2009, latest data available): 918 facilities 608 million tons clinker 789 million tons cement 26% of global cement production 17

18 Regional coverage Regional coverage (2009) South America ex. Brazil 37% North America 79% Japan Aus NZ 41% India 54% Europe 93% CIS 18% China 5% Central America Brazil 72% 72% Asia ex. China, India, CIS and Japan Africa + ME 34% 35% 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 18

19 Levers for CO 2 reductions 1. Energy efficiency small impact; new plants already highly energy efficient 2. Alternative fuels co-processing biomass and waste materials 3. Blending materials using substitutes for clinker 4. Carbon Capture and Storage not yet ready 19

20 Energy consumption per region India is most efficient region Driver: high energy prices 20

21 Alternative fuel use (2009) 2009: 88% fossil fuel; 9% fossil waste; 3% biomass Europe leads on fossil waste (>20%); Brazil on biomass (10%) Models assume 25-60% alternative fuels by

22 Clinker to cement ratio Average: 76% Blending material: Slag Fly ash Limestone Pozzolana Models assume ratio 70-73% in future 22

23 Net CO 2 per ton cementitious Text 23

24 Summary: Levers for CO 2 reduction Clinker Substitution and Alt Fuels Investment in Pre-calciner technology 24

25 Good progress, well documented % change Net CO 2 / tonne clinker, kg/tonne Net CO 2 / tonne cementitious, kg/tonne Heat Consumption, MJ/tonne clinker % Alternative fuel Clinker/cement ratio, % ,6-9 Electricity Consumption kwhr/tonne cement

26 CSI Summary Sustainability is important to CSI companies Licence to operate & access to resources Opportunities as well as risks Positive performance by companies Reductions in emissions of CO 2, dust, NO x, SO x, Public reporting and third party verification Engagement with stakeholders Rehabilitation of quarries Companies work actively on today s challenges Fatalities Climate change Biodiversity and land use management Water Role of concrete in sustainable construction 26
