Our Team

Founders

Fertetics Mandy
Founder-Owner, Managing Director, Lead Consultant, Accredited ESG Advisor

I am a sustainability expert with a background in economics and environmental management, educator, trainer, and transformative team coach. For 25 years, I have worked in sustainable business models and responsible corporate governance, striving for a better world. I combine sustainability development with organic organizational development and have extensive experience in sustainable procurement, stakeholder engagement, reporting, strategy development, business ethics, and diversity and inclusivity.

With international experience, I have conducted more than 25 sustainability audits worldwide (e.g., China, India, USA), gaining hands-on insight into supply chain sustainability.

As a lecturer, I teach at Corvinus University of Budapest MBA and Executive MBA programs, as well as at METU’s sustainability courses, and I am an instructor in accredited ESG advisor programs at both institutions. I have taught in more than eight cohorts of the Sustainable Business Academy’s Certified Sustainability Manager (CSM) program since its inception. I also play an active role in founding and serving on the advisory board of the Hungarian Sustainability Professionals Network, and I am co-founder and jury chair of the Sustainable Procurement Award.

In 2023, I was named among the Top 25 most recognized sustainability experts, and students of the CSM program have repeatedly awarded me the recognition of “most practice-oriented instructor”.

My passions include diversity and inclusion, supporting social entrepreneurs, and developing self-awareness – for example, through psychodrama.

Urbán Katalin
Founder-Owner, Accredited ESG Advisor

I have more than 25 years of experience in sustainability performance measurement, reporting, data disclosure, and reporting standards (GRI, ESRS), as well as corporate EHS management, carbon footprint calculation, and SbTI-related work.

In 2021, I received the BCSDH Women Leaders Award for “achieving results with innovative development solutions and leading my teams to success.” In addition to my expert role, continuous development of my leadership skills is a priority for me.

I was responsible for preparing Hungary’s first sustainability report, was a member of the GRI Stakeholder Council, and as a GRI-certified trainer contributed to the training of over 120 professionals alongside Mandy Fertetics under the Alternate name.

I spent more than 10 years as EHS Manager at Grundfos Hungary before moving into a global role, and I currently serve as Global Head of Sustainable Finance at Grundfos.

At Alternate, I now participate as a silent partner and only occasionally teach or contribute to very few projects.

Team Members

Cseh Annabella
Sustainability Consultant, Accredited ESG Consultant

At the start of my career, I wasn’t sure where I was heading, but I soon realized I wanted work that goes beyond daily tasks and has a genuine positive impact on the world. I deliberately sought paths that intersected environmental protection, social responsibility, and systems thinking.

I earned my Master’s degree in Resource and Environmental Management at BME, studied urban development in the Netherlands, volunteered in climate-friendly municipal programs, and in 2023 obtained my Certified Sustainability Manager qualification. I also gained experience in multinational corporations in business development, client relations, reporting, and team leadership, which gave me firsthand insight into how organizations operate internally and how sustainability can be integrated.

As a sustainability consultant at Alternate, I have found my calling – combining my work experience with the values I believe in. I am primarily responsible for sustainability reporting and sustainable procurement, while also managing projects and client relations. Today, I do work where my professional expertise and personal values not only coexist but strengthen one another.

Szkalisity András
Sustainability Intern

I earned my MSc in Geography in 2025, and since September of the same year I have been a PhD student at the Doctoral School of Earth Sciences at the University of Szeged, as well as a sustainability intern at Alternate. Thanks to my family, I have paid attention to living sustainably from an early age. I mostly commute by bike, try to minimize my use of plastics, and strive for energy efficiency in daily life.During my geography studies, I learned a lot about sustainability but had limited opportunities to approach the topic from a corporate perspective. I believe corporate efforts toward sustainability will be one of the key issues of the 21st century, and I want to contribute to these efforts to the best of my ability.At Alternate, I participate in various consulting projects, such as preparing double materiality benchmark analyses, updating sustainability reports, and liaising with clients’ supplier networks.

I consider community awareness-raising important — I have organized local events as part of the national “TeSzedd” litter collection initiative and sustainability challenges. Our research on micromobility and energy poverty, in which I was actively involved, received professional recognition.

Tran Thanh An (Anna)
sustainability intern

I am a third-year Data and Business Analytics student at IE University with a particular interest in the intersection of technology and sustainability. My interest in sustainability began in high school when I participated in a sustainability seminar and then in a Peace Designer Project competition. There, my team and I developed a sustainability action plan and installed selective waste bins at our school — still in use today. I am interested in renewable energy, reducing food waste, and slow fashion. I believe that data-driven approaches play a key role in creating a more sustainable future. At Alternate, I support sustainability consulting projects through data collection, updating sustainability reports, helping develop training materials and educational blog posts, and working on brand materials.

Partners, that we worked with

As a micro-enterprise, it is important for us to surround ourselves with an outstanding network of experts whose skills or konowledge complement ours — allowing us to expand our capacity, impact, and competencies to meet our clients’ needs and address sustainability challenges. We collaborate with excellent specialists in areas such as noise management, environmental protection, diversity, organizational development, and accessibility.

Mandy has wide experience both in the NGO field and in corporate sector. We had the pleasure of working with Mandy (Alternate) within corporate framework, where efficiency, focused, professional work and pragmatic approach is highly needed and appreciated. She supported us in the process of developing our corporate sustainability strategy and created a fine balance among vision, strategical approach and operative management. Together we built up not just where we want to go in our sustainability journey, but we also clearly see the way before us and able to continue our walk on it.

Mandy has been an absolute asset to our team and contributed significantly to our current ESG infrastructure. I’ve had the pleasure of knowing Mandy for almost five years during which she was a part of the global Knorr-Bremse Corporate Responsibility department. Mandy has a strong ability to manage multiple stakeholders and create networks. This is one of the key reasons Knorr-Bremse was able to establish reliable processes to further develop the sustainability agenda company-wide. Here, Mandy contributed not only with her structured way of working but also with her grand knowledge of sustainability topics and her eagerness to stand up for the mission. I wish her the very best for the future and without hesitation I highly recommend Mandy if you are looking for someone with experience in sustainability.

The trainings and other events organized by Alternate are always characterized by a high level of professionalism and up-to-date knowledge. Their ‘helicopter perspective’ approach to topics is a great asset in our professional work.

I had the pleasure of working with Mandy (Alternate) for three years on Budapest Airport’s vital sustainability stakeholder engagement initiative. Her professional communications background and extensive network were key to designing, launching, and operating the Greenairport program. She is outstanding in the ESG field, a pleasure to work with, and it’s no coincidence that this project received the Ozone Green Award, the Delfin Award in Hungary, and the European Eco-Innovation Award from the Airport Council International.

Mandy did an excellent job as project manager for the 2022 EU Diversity Month. With 56 programs, Hungary achieved second place in Europe that year. Mandy successfully engaged numerous stakeholders from the corporate sector, civil society, and education to co-create and implement events around diversity and inclusion – raising awareness, sparking discussion, and encouraging learning. Through social media and press coverage, the program reached 1 million people.

We are very grateful for the professional expertise and comprehensive information – many of us now see the world differently.

We are proud to be among the top 15% with our EcoVadis silver rating – but we know that sustainability is not a finish line, it’s a continuous journey. In this process, expert support was particularly valuable: it helped us articulate our instinctive good practices in ESG language and receive meaningful, tailored feedback—not generic advice, but real directions for development.

Arató Gábor / Managing Director - Manupackaging International Kft.

Obtaining the EcoVadis certification was a completely new area for me – wiith new responsibilities and expectations, and a language quite unlike what I was used to in finance. In this complex and initially daunting process, the Alternate team, led by Mandy, provided not only professional support but also guided us as true mentors. With their help and advice, I gradually gained more confidence in navigating the many and complex requirements. What I especially appreciated was that we didn’t receive general template solutions, but recommendations and tools tailored specifically to our small company’s operations, culture, and resources. The documents and processes we developed weren’t just created to ‘sit in a drawer’ – they were implemented in a way that made them truly useful in our day-to-day operations.

The Alternate team contributed to our success and well-deserved pride in achieving the EcoVadis silver rating not only with their expertise but also with their empathetic and collaborative approach. I wholeheartedly recommend them to anyone embarking on a similar journey.

Szantner Judit / Head of Quality and Sustainability - Manupackaging International Kft.

We first contacted Alternate in preparation for the EcoVadis assessment. We worked together over about four months in a customized mentoring process. From the very beginning, the expertise and experience they brought gave us a sense of security, especially important in such a complex process where we had no prior experience. Mandy and her team provided thorough, well-structured, and tailored support. We never felt like we were receiving a generic solution, but rather practical help adapted to our situation. During the process, we didn’t just prepare for the assessment—we also evolved: set new goals and launched internal processes that will support our long-term sustainability performance.

We were satisfied with both the results and the collaboration—so much so that we decided to continue working together beyond the project.
