Using Copper to Achieve A Sustainable Future

A more sustainable future relies on the use of copper. The need to build structures that are healthy for their occupants and use less electricity and water, makes copper the top material choice for architectural and interior elements, building system controls, plumbing and HVAC equipment, mechanical systems and appliances, and energy generation, storage, and electrical applications.

Why is copper critical to a green and healthy building?

Copper’s versatility is a plus for better building construction, needed for structural necessities to aesthetic adornments, including roofing, wiring, renewable energy applications, and plumbing.

Life Cycle Assessment - Copper Tube and Sheet

As an association committed to promoting the sustainable use of copper materials, CDA developed a life cycle assessment (LCA) for copper tubes and sheets produced in North America in accordance with ISO 14040/44 and ISO 21930. With a cradle-to-gate scope, this LCA can be used by manufacturers as an input to their own product-specific LCAs and Environmental Product Declarations (EPDs). Additionally, this data was incorporated into the GaBi database allowing for quick and efficient use of the results.  For a list of participating manufacturers, please contact

3E Exchange

One of the biggest hurdles for today’s manufacturers exploring options to streamline the safety of their products is gathering product and material data efficiently from suppliers. CDA and 3E Exhange have improved manufacturers’ abilities to achieve full material disclosure for safer product design through their publication of over 700 shared materials, which represent all the active wrought and cast copper and copper alloy products registered in the Unified Numbering System (UNS) for alloy designations, on the 3E Exchange platform. Each shared material contains information on the alloy’s contents, potential health, safety, and environmental impacts, and their status with various regulatory schemes like REACH and RoHS. This puts material transparency directly at the fingertips of manufacturers using or seeking to use copper and copper alloys, supporting their ability to meet product compliance requirements and obtain sustainable certifications for their products more easily.

Sustainable Minds

CDA has partnered with Sustainable Minds to share copper industry standard-based Health Product Declarations (HPDs). Sustainable Minds transparency catalog offers a streamlined platform that is searchable by Construction Specifications Institute (CSI) Division number making it easier for architects, engineers, and contractors to find, search, and specify products with transparency disclosures. The ASTM/ASME standards that were leveraged in the development of CDAs standard-based HPDs are linked within each individual CDA listing for reference and ease of use.
