Our Team

Established in 2020, Planet Fanatics’ Network is an innovative consultancy business built on the founders’ more than 20 years of sustainability experience – domestic and international -, both from the corporate and the civil sector. Sustainability strategy, responsible corporate governance, training and conferences, sustainable product portfolio, corporate climate strategy, EU climate roadmap, responsible investing audit, sustainability reporting, community solar panels and volunteering… The number of innovative, exciting and truly meaningful projects in the Planet Fanatics Network’s portfolio is almost endless, while the implementation is never lacking outstanding expertise, unwavering enthusiasm and the support of a professional network from within the industry.    

In recent years, Planet Fanatics’ Network collaborated with several of the industry-leader corporations of key markets, assisting them towards more sustainable and transparent operations. These processes involved a detailed procedure for drawing up a sustainability strategy, as well as the publication of a sustainability report in accordance with international standards (GRI, SASB, GHG Protocol). Similarly important stages are the coordination of internal ESG-procedures, and the support of awareness building throughout the supply chain. For the first time in Hungary, Planet Fanatics’ Network has published the ESG-rankings of corporations with largest revenues, with the purpose of strengthening the culture of corporate responsibility in the country. 

Our sustainability consultants consider it a priority to support civil organizations and educational institutes with the work they do. In light of this, Planet Fanatics’ Network has established valuable partnerships with WWF Central and Eastern Europe, WWF Hungary and Patrónus Ház among others. We are proud to have supported Bátor Tábor in publishing their first sustainability report in 2022, as the first ever foundation to publish a GRI 2021 standard report and that we can be involved in their biannual report ever since. We support human resources and equality issues in the workplace through the  Egyenlítő Alapítvány to promote diversity and inclusivity.
