Mueller Water Products, Inc. (MWA) — ESG & Values Scores

Environment story

Mueller Water Products discloses established reduction targets for GHG emissions, internal water withdrawal intensity, and waste-to-landfill, indicating a structured environmental management approach. However, the company has not disclosed specific Scope 1, 2, or 3 emissions figures, nor has it announced a quantified net-zero target year. The 10-K acknowledges that many manufacturing plants use significant electricity from fossil-fuel sources, creating material climate risk exposure. The company faces a CERCLA PRP liability from a former U.S. Pipe facility near a Superfund site in North Birmingham, Alabama, though indemnification agreements with Tyco successors provide partial protection. Environmental capex is stated as immaterial. The absence of disclosed emissions baselines, third-party verification, and a time-bound net-zero commitment significantly constrains the environmental score, despite stated focus on water-use minimization and manufacturing water-quality standards.
