Contents Letter from our Chief Executive Officer and Technical Committee Chairman Letter from our Chief Financial Officer About FibraShop Our 2021 Annual Sustainability Report 77 FIBRA SHOP Supply CHAIN GRI 2-6 Our commitment to sustainability goes beyond the limits of our or- ganization. We also encourage other organizations to work on min- imizing their negative impacts on the environment and society. To this end, we created a Responsible Sourcing Policy through which we extend our ESG responsibility to suppliers, defining criteria for responsible acquisition of goods and services and sustainable man- agement of our supply chain, to ensure it operates in line with our values, goals, guidelines and policies. To continue this effort, in 2022 we will be developing a procedure for supplier evaluation and a questionnaire that incorporates envi- ronmental, social and governance aspects. The goal will be to analyze our supply base both at the time of selection and in regular reviews throughout our commercial relationship, to identify the ESG risks that may be present in the supply chain and determine its impact on the environment and society. Based on the results of this evaluation and the findings of the questionnaire, we will develop action plans and/or preventive or mitigating measures, as the case may be.

With a new outsourcing law that took effect last year, the corporate pur- pose of our specialized service suppliers was modified to specify the services to be supplied, job descriptions were closely reviewed to ensure they coincided with the "specialized service," and finally new service provision agreements were signed among the compa- nies of the group.
