Green Building with BREEAM Materials Mat 1: Materials specification Criteria Hilti contribution Aim In 2009 Hilti began measuring the product carbon footprint (PCF) for all products. We To recognize and encourage the use of are dedicated to working closely with our customers and suppliers to reduce carbon construction materials with a low envi- emissions. In working toward this target, we take into account all life cycles of a Hilti ronmental impact over the full life cycle of product starting with the material extraction/provision, internal production, transporta- the building. tion, product usage and end of life. All Hilti products will be analyzed by using the PCF with the aim to reduce the carbon footprint of the next generation of Hilti products. Assessment criteria: A nationally recognized LCA tool has to By understanding the PCF of our products and having full transparency on major be used in line with the international ISO impact factors, Hilti will also reduce the CO emissions of its products in the coming 14040/14044 standard to evaluate mate- 2 years. We follow existing standards (ISO 14040/44, PAS 2050 and first drafts of ISO rial specification according to the CO2 14067) and work closely together with an external partner in Germany. The PCF data contained in the material. provided is partly based on the databases GaBi and ecoinvent (e.g. materials, produc- tion processes etc.). Additionally, Hilti participates in essential associations and con- ferences to ensure the highest possible credibility of PCF data for customers. Example: HUS-H 10x75/5/15 The total CO emissions of a package of HUS-H 10x75/5/15 anchors are almost 15 kg. 2 Looking at the 5 life cycles (see table below) it becomes clear where the CO reduction potentials are: 2 • Material extraction/provision, with 6 kg, is responsible for about 40% of the total CO2 emissions of the anchor and thereby offers the greatest reduction potential. • The production phase of the anchor is the second main source of CO emissions 2 (3.42 kg). Hilti is constantly implementing new innovative production technologies to reduce associated CO emissions. 2 Material Production Transport Usage End of life Global Warming Potential (GWP 100 years) 6.16 3.42 1.64 1.51 1.82 Total CO : 14.36 kg 2 page 16
