Sustainability: Extrusion EPDs and LCA

Aluminum Extrusion Environmental Product Declarations and Lifecycle Assessment

Environmental Product Declarations (EPDs) have been called "Environmental Nutrition Labels" for materials and products, describing the potential environmental impact of a product through its life cycle.


In October 2016, the Aluminum Extruders Council released the most comprehensive industry-wide set of Environmental Product Declarations (EPDs) to date that document the environmental performance of aluminum extrusions produced in the U.S. and Canada.

The EPDs quantify the “cradle-to-gate” lifecycle environmental impacts of aluminum extrusions. One EPD is for thermally-improved extrusions – of particular interest for fenestration applications – and one covers extrusions that have not been thermally improved. Both provide data for mill finish, painted and anodized products, so architects and designers can assess the environmental impacts of finishing and thermal improvement decisions.

AEC Aluminum Extrusion LCA

A Life Cycle Analysis (LCA) or EPD Background Report is the precursor to the EPD. In addition to presenting the conclusions shown in the EPD, it will provide additional detail about items such as:

  • Inputs at each process step
  • Secondary data sources employed
  • Key assumptions & allocations
  • Assessment of alternative scenarios re: key inputs
  • Data quality & completeness assessment

The AEC EPD’s are based on a detailed study of the process inputs and outputs of 11 AEC member extruders. Thirty separate facilities, located across the U.S. and Canada, with more than 85 extrusion presses and a variety of finishing and thermal improvement facilities, were included in the study. In aggregate, extrusion production of 1.7 billion pounds, or about one-third of the North American total for 2015, was covered in the study.

The Aluminum Extruders Council (AEC) has achieved a UL Environmental Product Declaration (EPD) certification. The UL EPD certification mark indicates that UL has independently reviewed and certified the manufacturer's environmental impact disclosure that constitutes the EPD. For more information, visit
