SAN JOSE, Calif., Oct. 27, 2025 (GLOBE NEWSWIRE) -- H2O America (Nasdaq: HTO), one of the nation’s largest investor-owned water and wastewater utilities, has been recognized as one of America’s Greenest Companies 2026 by Newsweek and market data research firm Plant-A Insights Group. The award recognizes H2O America’s commitment to sustainability across its national footprint, which includes local operating companies in California, Texas, Connecticut and Maine. H2O America is one of only three water utilities recognized on the list of 450 companies honored by Newsweek.

Some of H2O America’s actions towards greater sustainability include¹:

• GHG emissions: Achieved a 43% reduction² in Scope 1 and 2 emissions from the 2019 baseline, progressing toward the 2030 goal of 50%.
• Renewable energy: Increased solar generation by 73%, with eight new solar projects, including the first in Texas.

Newsweek and Plant-A Insights Group selected the top 450 companies in collaboration with GIST Impact, a leading impact data and analytics provider, by conducting research and analysis of sustainability data from both public and private companies in the US. To ensure the highest standards, only companies that meet the European Union's stringent sustainability criteria – considered the most advanced globally – were eligible for consideration.

Criteria for the evaluation and scoring of America’s Greenest Companies included over 25 parameters in four main categories: greenhouse gas (GHG) emissions, water usage, waste generation, and commitment and disclosures.
