Hi, I’m Mari Barnhoorn, a dual Dutch-South African professional based in Rotterdam, pursuing an MSc in Global Business & Sustainability at Erasmus University. I combine hands-on ESG work with academic research, currently writing a thesis in collaboration with PwC’s human rights working group, focusing on how CSDDD and ESG legislation shape corporate practice. Through roles at PwC and my involvement with STAR, I’ve built experience in sustainable finance, KPI reporting, CSR, and stakeholder engagement. I’m passionate about responsible business, human rights, and making sustainability actionable through pro bono projects and community programs, while continuously developing my cross-cultural communication and analytical skills.
