Welcome, I am
Ruth Elisa Castro Cerón.
Mother, wife and daughter, who always wondered if my purpose in life was what I did at work.


After leaving my comfort zone, I understood that my experience of more than 20 years as an employee, leading more than 30 companies towards recognition in environmental and sustainability issues, could be shared to help other people and organizations better understand the tools of sustainability. My goal is to unite efforts and knowledge for a common benefit.


The FAN ESG Methodology summarizes everything I have studied, learned, deciphered and unified in a didactic and simple way to reach all people so that they understand what sustainability is and how to achieve it.
My profession and credentials to give you more confidence about my work:
​
-
Chemical engineer
-
Master in Environmental Management and Engineering
-
Candidate for Master in Renewable Energy and Climate Change
-
Project Management Professional, GRI Certified Training,
-
Certified: Sustainable production, ISO50001, ISO14001, ISO9001
