CWT California Water Service Group

As a reflection of the utility’s ongoing commitment to sustainability and corporate citizenship, Newsweek today named California Water Service Group (Group) (NYSE: CWT) one of “America’s Most Responsible Companies” for 2025. This is the fourth consecutive year that Newsweek and Statista Inc., a leading statistics portal and industry ranking provider, recognized Group with this honor.

Group was one of only three investor-owned water utilities ranked in the Energy & Utilities category. The 2025 list spans 14 industries and recognizes the top 600 out of the 2,000 largest public companies by revenue.

America’s Most Responsible Companies were selected this year based on 30 publicly available key performance indicators (KPIs) derived from corporate social responsibility, sustainability, and other reports, along with independent survey results. The KPIs focused on company performance in environmental, social, and governance (ESG) areas, while the survey asked respondents about their perception of company activities related to corporate social responsibility.

“We have long operated by the mantra to always “do the right thing”—not simply the easy thing—for our customers, communities, employees, and stockholders, and for the environment,” said Martin A. Kropelnicki, Group Chairman & CEO. “To be recognized for our efforts by Newsweek for the fourth year in a row is an honor we do not take lightly, and we will continue striving to enhance our efforts each year to do right by those we serve.”
