    Mariana Ortega Ramirez
    Mariana Ortega Ramirez
    Junior Sustainability Analyst

    Mariana joins EarthShift Global after building a thriving sustainability consulting practice focused on agriculture, forestry, livestock, and fishing, with special attention on mapping of stakeholder perspectives.

    “These sectors attract me because they’re the basis of sustenance, and encompass so much that is alive, beautiful, and meaningful,” explains Mariana, who holds a bachelor’s degree in environmental engineering and a master’s in industrial ecology.

    Her specialty is the relationship between natural resources, climate change, and public policy. On behalf of clients like the World Bank Group for National Institute of Ecology and Climate Change, the Mexican Fund for Nature Conservation, and Mexico’s Ministry of the Environment she has pursued problem-solving and development of implementation schemes that emphasize innovation, communication, and understanding of socio-ecological systems.

    Mariana’s interests date to her childhood, when she accompanied her mother, an agronomist who promoted organic agriculture, on visits to small farms.

    She cultivated the connection as an undergraduate at UPIBI-IPN Instituto Politécnico Nacional & Técnico in Mexico City, where she calculated farm GHG emissions in an industrial ecology research project, and later working at the Mexican arm of the United Nations Food and Agriculture Office.

    She subsequently conducted projects for consulting firms (CINPRO, MGM Innova), government agencies, and as a climate change specialist at the NGO founded and led by Nobel Prize-winning atmospheric chemist Mario Molina (https://centromariomolina.org/english2/).

    While earning her master’s degree at Leiden University – TU Delft & Graz University in the Netherlands, Mariana met and befriended two future EarthShift Global colleagues: analyst Juanita Barrera, a classmate, and senior sustainability analyst Valentina Prado, who was their Life Cycle Assessment (LCA) professor.

    “After graduating I returned to Mexico and worked on projects mostly connected to public policy,” says Mariana. Focal points include design and quantification of indicator sets for environmental monitoring and evaluation, calculation of emission inventories, and development of LCA studies.

    A systems thinking perspective developed during her master’s studies is central to Mariana’s approach. “Besides LCA, I studied ethnographic research and the ‘follow the thing’ approach, as opposed to the method of ‘following the people.’ It’s like a qualitative LCA that also integrates history and storytelling and makes you question what is behind anything that humans consume,” she recalls. “So now my work mixes very technical calculations with workshops or interviews on stakeholder needs and wants, and what’s needed for advancing sustainability projects besides money or technology.”

    She notes that perceptions of mitigation and environmental issues have evolved in recent years. “It’s sometimes challenging to discuss those with stakeholders; the actions involved can be complicated and often don’t render immediate tangible results. But climate change mitigation actions are much more recognized nowadays both in public policy and NGO projects.”

    Mariana’s joining EarthShift Global was driven partly by her passion for the LCA process but also by close alignment with the company’s mission and activities. “It’s an unusually good match,” she says. “I’m most looking forward to helping create knowledge that can improve social and environmental performance.”

    Mariana’s active volunteer work includes research and communication for the Alliance for Our Tortilla (http://www.ipsnews.net/2018/05/mexico-want-put-tortillas-table/), which supports and preserves traditional methods for producing tortillas, a source of low-cost nutrition that is central to the gastronomy of Mexico and other countries.

    Zeynab Yousefzadeh
    Zeynab Yousefzadeh
    Junior Sustainability Analyst

    Trained in materials engineering and industrial management,  Zeynab Yousefzadeh, brings to us a unique combination of engineering, management, and data skills, and a record of successfully advancing sustainability in a mining-oriented industrial organization.

    That organization, Iran China Clay Industries Co., is a major supplier of Kaolin (white clay) to a range of industries across the Middle East. Zeynab joined it in 2005 after earning a materials engineering degree from the University of Tabriz. She quickly began applying her skills to help better integrate the organization’s sales and production departments while also spotting opportunities for waste reduction that could help build new business lines.

    Accomplishments included utilizing lower-grade clay that had to be removed to reach deeper higher-grade material; the lower-grade clay’s different colors proved useful in producing face brick for buildings. She also helped integrate into paint production fine high-quality clay that was a byproduct of processing and had not previously been collected. But the largest advance was her R&D contribution to adopting silica sand waste for making aerated autoclaved concrete (AAC). This type of brick is an increasingly popular lightweight material with a number of sustainability advantages for building construction, especially in areas with high temperature variation.

    Between 2019 and 2021, under the supervision of Dr. Shannon Lloyd, Zeynab earned a second Master’s degree at Montreal’s Concordia University; her thesis was on Prospective Life Cycle Assessment in Surface Engineering. In her research she served as an LCA analyst for Green Surface Engineering for Advanced Manufacturing, leading several full-scale comparative environmental LCAs and receiving Concordia’s Sustainability Research Award for her project, Dissemination of Life Cycle Assessment Methods to Surface Engineering Researchers.

    In addition to her sustainability engineering work, Zeynab writes environmentally focused articles for MÉDAD Persian E-magazine of Montréal and has also developed a series of outdoors videos with her partner Hani Sadati.
