Fiacro Jimenez Ramirez

Yale School of the Environment

My name is Fiacro Jimenez Ramirez. I am an international student from Mexico City where I studied my bachelor’s degree in Politics and Public Administration in El Colegio de México. In 2020 I started my career as a professional in the field of environmental policy as I joined the Ministry of the Environment of Mexico City. For two years I was responsible for the evaluation, monitoring and improvement of the city’s social rainwater harvesting program (the largest rainwater harvesting program in the world for urban environments), which provided sustainable access to clean water to the most vulnerable households in the city. As part of my responsibilities, I was also in charge of leading the Ministry’s sustainable finance efforts. As I learned more about the intersection between policy, finance, and the environment, this led me to take the next step in my career; thus, in 2022 I joined the Federal Ministry of Finance of Mexico with the team responsible for the country's sustainable finance efforts. There I was responsible for Mexico’s portfolio in the Global Environment Facility, while also providing support for to the Ministry’s key efforts in the development of the National Sustainable Taxonomy, development of the national emissions trading system, and participation in high level fora such as the G20 and COP27.

Joining YSE as Fulbright and a Three Cairn Scholar, during my time in the master in environmental management I am focusing on developing my technical skills in terms sustainable finance. As I further specialize in the field of business and the environment, I plan to take courses such as Renewable Energy Project Finance and Corporate Finance; while simultaneously taking advantage of Yale’s extensive network in the environmental work. In line with the latter, with the help of YSE and the Three Cairns Group I will be joining the Mexican delegation in COP28 as part of the team responsible for the Sustainable Finance track.

Ultimately, after graduation in 2025, I intend to further develop my career in the field of sustainable finance becoming a professional capable to bridge the distance between the fields of politics, finance and the environment, whether through government action, private sector or through a multilateral international financial institution.
