LCA Executive Certification (CLE)

New Certification: Life Cycle Executive

The American Center for Life Cycle Assessment (ACLCA) announces its new certification for Life Cycle Executives. This certification demonstrates that the individual understands the basics of LCA, and can interpret and communicate LCA results to the general public.

The certification was developed in conformity with the ISO 17024 standard.

The CLE certification is especially useful for individuals such as architects and product specifiers, purchasing agents, environmental managers, sustainability managers, educators and individuals who hire contractors to perform LCA studies.
