Emilio has collaborated on ESG and environmental performance audits, helping companies meet international standards and clearly communicate results to banks, investors, and sustainability rating agencies. His perspective combines international reporting frameworks with business needs, enabling access to sustainable financing and strengthening the social license to operate. A certified consultant and auditor, he supports companies and banks in managing climate-related risks, assessing valuable opportunities during the energy transition, and conducting technical and sustainable project evaluations. His experience also allows him to transform operational and environmental metrics into metrics that are understandable to the bank's finance department, helping to improve investment decisions and make them more informed and aligned with resilience and decarbonization goals. In his role as Chief Mining Officer, Emilio promotes operating models that seek to increase productivity and safety, while reducing the environmental footprint and strengthening the industry's reputation with global stakeholders.
