What is an Environmental Product Declaration (EPD)?
An Environmental Product Declaration (EPD) is an independently verified and registered document that communicates transparent, comparable data and other relevant information about the life-cycle environmental impact of a product in accordance with ISO 14025.
Multiple datasets are included in an EPD: resource consumption of energy, water and renewable resources, and emissions to air, water and soil. This data is aggregated using multiple environmental impacts including contributions to climate change (carbon footprint), resource depletion, and air, water and soil pollution.
What does the EPD for ‘Galvanizers Association of Australia: Hot Dip Galvanizing in Australia’ cover?
The EPD provides an industry average environmental impact of hot dip galvanized steel in Australia conforming to the requirements of AS/NZS 4680. It covers steel products, such as hot-rolled structural steel sections, steel plate, and hollow structural steel sections, that are hot dip galvanized after fabrication by members of the GAA. As such, it represents the industry average for members of the GAA.
The declared unit for the EPD is 1 year of protection of a 1 m² coated 8 mm thick steel plate. The scope is ‘cradle-to-gate with options’ covering production, transport to customer, end of life and recycling potential. A guide is provided to adjust the average EPD and apply it to align with specific product.
The average impact of the hot dip galvanizing process, excluding the steel data, is also listed. This enables users to take EPD data for a specific steel product and calculate a more accurate environmental impact of the galvanized product.
Who was involved in the EPD?
The EPD was produced by thinkstep ANZ using data from our Australian galvanizing members provided and it was verified by start2see.
Who are the Australian galvanizing members of the GAA?
All of our Australian galvanizing members details are listed in the Galvanizers section of this website.
