This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.
Cosan S.A. operates through its subsidiary Comgás, the largest natural gas distributor in Brazil, serving over 2.3 million residential, commercial, and industrial customers across São Paulo state. This regulated utility business constitutes a core segment of the conglomerate's integrated energy and logistics portfolio. The company's operations are centered on the distribution and sale of piped natural gas, a fossil fuel, to end consumers.
While Cosan has diversified into bioenergy and sugar production, its natural gas distribution network remains a foundational and material part of its business. There is no publicly announced plan to phase out this fossil fuel infrastructure or transition the utility's service to renewable energy sources. The company continues to derive significant revenue from the combustion of natural gas by its customer base.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.
