Abstract: Brazilian sanitation companies disclose their sustainable practices through sustainability reports as part of their commitment to Sustainable Development Goal (SDG) 6 of the 2030 Agenda, which aims to ensure universal access to water and sanitation. This study proposes a methodology to evaluate how these companies integrate Environmental, Social, and Governance (ESG) principles into their management and disclosure practices, rather than assessing service delivery or operational outputs directly. These indicators were applied to the sustainability reports of Brazil’s three largest sanitation companies: Sabesp (Companhia de Saneamento Básico do Estado de São Paulo), Copasa (Companhia de Saneamento de Minas Gerais), and Sanepar (Companhia de Saneamento do Paraná). The results indicate that all three companies have incorporated sustainability into their competitive strategies and corporate governance practices. Sabesp demonstrated a stronger adherence in the environmental and governance dimensions, Copasa excelled in social performance while also performing well in governance, and Sanepar exhibited the lowest adherence among the three. Hence, we present a methodological framework for monitoring corporate ESG performance and governance practices aligned with SDG 6, focusing on their management and disclosure practices, rather than directly assessing service delivery or operational results.
