Established through a partnership between the Federal Comptroller General (CGU) and the Ethos Institute of Business and Social Responsibility, since 2010 Pró-Ética encourages Brazilian companies and multinationals operating in Brazil to implement measures that can improve the corporate environment more integrity, ethical and transparent, especially in relations involving the Public Administration.

Participation in the Program is voluntary and is carried out by completing evaluation questionnaires. In the 2020-2021 edition, 327 companies of all sizes and from various business requested access to the program, of which 195 were admitted and, after the evaluation process, 67 companies were approved and recognized as Pro-Ethical Company 2020-2021 .

The results obtained by Copel serve as a thermometer for the functioning of the Company's Integrity Program, which constitutes a set of mechanisms and procedures with the purpose of promoting the correct treatment of ethical and conduct deviations and, mainly, the implementation of anti-corruption measures .
