3 Policy: Sustainability Ambitions 2020 Sustainable operations Strong positioning towards all stakeholders Acting for sustainable construction with concrete Contribution to biodiversity Protecting our climate Using waste as a resource Reducing all other environmental impacts Assuming our social responsability HC delivers sustainable building materials, which positively contribute to the protection of the environment during and after their lifetime HC delivers a prominent positive contribution to Biodiversity, and builds up a leadership position in the promotion of biodiversity HC continuously acts for minimizing its greenhouse gases emissions HC minimizes the use of natural resources and offers solutions for a sustainable waste management HC is best-inclass in minimizing and managing its environmental impacts HC cares for the safety and satisfaction of its employees, its customers and the local communities Slide SMM AINSI B.

6 Using waste as a resource Gas; 0% PPDF 40; 12% PPDF 90; 2% Anodestof; 25% Glycolbottem; 6% Bruinkool; 11% Finecokes; 5% Papierslib; 1% Bedcokes; 3% Diermeel; 6% besparing van 92 Mm 3 aardgas jaarverbruik van huishoudens ¾ van de bevolking van Maastricht Zuiveringsslib; 29 %

7 Best in class Fitness programme: Europe: av. clinker content 79% (2006) ENCI: 48% (2007) Ggbf slags and e-fly ashes to partly replace clinker Double savings: fewer primary resources reduced energy thus less CO 2 ENCI heeft met 48% het laagste klinkeraandeel van Europa

8 Reducing our environmental footprint World - Portlandcement: 920 kg CO 2 / ton cement ENCI Portlandcement: 710 kg CO 2 / ton cement ENCI Hoogovencement: 230 kg CO 2 / ton cement Cement consumption % man - made CO 2 : World = 5%, EU = 3% Benelux = 2% ENCI heeft haar CO 2 emissies met 28 % verlaagd

22 Cradle-to-cradle: the goal is quality ECO-EFFECTIVENESS DEFINE, INCREASE, SUPPORT, OPTIMIZE ECO-EFFICIENCY

23 Vision for the future: C2C cement and concrete Safe and beneficial when staying in the environment Material cycles Happy neighbours to cement kilns Energy from current solar income Positive footprint: e.g. air cleaning, source of nutrients

24 Steps on the way to C2C All of Heidelberg Cement: 100% Cradle to Cradle cement and concrete 100% Renewable energy Established nutrient cycle Entirely A or B materials and fuels Entirely A or B raw materials Expand to other plants Develop Recycling scheme ECO-EFFECTIVENESS Innovative cement All inputs are types C2C acceptable ECO-EFFICIENCY Air cleaning Use of wastes 100 % 0%
