Master's student in Finance, Anwvli Austin Oluh, has been awarded the 2026 ISEG ESG Prize for his final master's thesis, which developed an Artificial Intelligence tool to identify 'greenwashing' in major European companies.

The winning project, titled “Talk Without Walk: A Transformer-Based Measurement Framework for Corporate Greenwashing from Verbal Disclosures”, proposes an innovative solution to analyze the verbal communication of executives from companies in the STOXX Europe 600 index, between 2012 and 2022. Using advanced Natural Language Processing (NLP) models, the study correlates the intensity of environmental discourse with companies' actual ecological risk incidents.
The ISEG ESG Award, a joint initiative by ISEG – Lisbon School of Economics & Management, the Lisbon City Council, and NTT DATA, aims to recognize academic excellence in sustainability and ESG, encouraging practical and innovative solutions. This year's edition, themed “Innovation for a Sustainable Future,” received over 20 submissions, with six finalists selected for the final pitch session.
Anwvli Austin Oluh participated in the online presentation session for the finalists, where the award was presented by Cinzia Simão, Principal Director at NTT DATA. The organization expressed gratitude to all participating students and the finalists for their contributions to reflection and research on sustainability challenges.
The jury, comprising Nuno Caleia (Division Chief of the Lisbon City Council), Professor Helena Jerónimo (Vice-President of ISEG and Jury President), and Cinzia Simão (Principal Director of NTT DATA), evaluated the works and selected the winner.
