Our commitments

CSR: Byron Group awarded SILVER medal by Ecovadis

Since 2016, Byron Group has been committed to a CSR approach with the ECOVADIS organization. Our current status is SILVER, which places Byron Group among the top 5% of suppliers rated by the organization (Ecovadis Assessment 2024).

 

Pay equity: Byron Group scores 98/100!

Achieving a score of 98/100* in 2025 means that Byron Group is a company that is highly committed to promoting gender equality in pay.

Pay equity is important because it aims to eliminate unfair pay gaps between men and women. In many companies and industries, women are often paid less than men for equivalent work. Achieving a score of 98/100 indicates that Byron Group has successfully achieved a high level of pay parity between men and women, meaning that employees of both genders are paid fairly for the work they do.

This has a positive impact on employee productivity and motivation, as they are aware that their contributions are valued and rewarded fairly.

In accordance with the provisions of the Avenir law, which aims to eliminate the gender pay gap, Byron Group is committed to publishing its results:

Indicator of average gross annual pay gap per FTE: 38/40

Individual increase rate deviation indicator: 35/35

Indicator of female employees who received a raise in the year following their return from maternity leave: 15/15

Indicator of the number of employees of the underrepresented gender among the 10 highest paid: 10/10

*Reference period selected: January 1, 2025, to December 31, 2025.
