An EPD is a comprehensive disclosure of a product’s environmental impacts associated to the different stages of its life cycle, from its creation, use, to disposal, and other relevant information in accordance with recognised international standards (e.g. ISO 14025 - Type III Environmental Declarations, EN 15804 Sustainability of construction works - Core rules for construction products). EPDs bring credible transparency since they rely on an objective scientifically accepted approach and are third-party verified and publicly available.
Early in 2014, Holcim New Zealand worked with one of their main customers, Allied Concrete, to become the first concrete manufacturer to publish an EPD in Oceania. Allied Concrete aspires to be a sustainable and environmentally conscious organisation and is running a sustainability programme to improve the use of energy and resources. The EPD published in July 2014 provides information for 1 m3 of normal pump or standard grade ready-mixed concrete for a number of compressive strengths covering the range made with Holcim-manufactured cement (i.e. 28 concrete batching plants).
Thanks to this, Allied Concrete won the “Extra Distance Award 2014” from the New Zealand Ready Mixed Concrete Association. The judge’s report commented “The judges were impressed by the courage shown by Allied Concrete in obtaining an EPD and in so doing leading the way forward on behalf of the concrete industry. Not only was the time and resource expended significant, but the foresight in openly acknowledging the environmental impact of their product to accurately assess efficiencies is very responsible.”
Holcim New Zealand was instrumental in that success in that it made the environmental impact calculations for Allied Concrete using the tools that were developed by the Cement Sustainability Initiative (CSI) and Holcim
