The oil and gas industry has evolved into a water industry. Demands on using, handling and treating water are paramount today. Environmental, social, and governance (ESG) criteria are a set of standards for a company’s operations that socially conscious investors use to screen potential investments. Environmental criteria consider how a company performs as a steward of nature. Social criteria examine how it manages relationships with employees, suppliers, customers, and the communities where it operates. Governance deals with a company’s leadership, executive pay, audits, internal controls, and shareholder rights. Problems related to ESG issues - water discharge, toxicity, radio-active scales, H2S, etc. leave clients needing chemicals and solutions to address them properly.
