Developing the Materiality Matrix at Telefónica

by Robert G. Eccles, George Serafeim and Asun Cano-Escoriaza


Telefónica, one of the largest telecommunication companies in the world and headquartered in Spain, has been issuing a corporate sustainability report since 2002. In its 2011 Sustainability report, the company included a "materiality matrix," and was one of only five of the 97 companies in Spain that produced a sustainability report that year. The case describes the purpose of the materiality matrix, how it was developed, and the opportunities the company sees for improving it.
