The America's Climate Leaders ranking, presented by USA Today in partnership with Statista, identifies U.S.-based companies that have achieved meaningful reductions in Scope 1 and Scope 2 greenhouse gas emissions relative to revenue. The 2026 list evaluates companies with more than $50 million in revenue and independently reported emissions data.

"We've made strong progress by setting clear, measurable goals and holding ourselves accountable to them," said Robert J. Pagano, Jr., CEO, President and Chairperson of the Board at Watts. "After exceeding our initial emissions intensity targets, we've set a new goal to reduce water, GHG and hazardous waste intensities by 3% annually, in addition to reducing our absolute carbon emissions by 10,000 MT by 2034. That progress is driven by a disciplined operating approach and continued investment in more efficient, sustainable technologies across our business."

Watts has embedded sustainability into its broader business strategy, focusing on improving energy efficiency, reducing emissions, and advancing water conservation across its operations. Between 2018 and 2023, the company achieved a 62 percent reduction in water intensity, a 60 percent reduction in market-based emissions intensity and a 35% reduction in hazardous waste intensity, significantly surpassing its original targets. Since 2014, Watts has reduced more than 80 million liters of water globally through investments in operational efficiency and conservation measures.

Watts also incorporates sustainability into its product development process. In turn, its solutions help improve the efficiency and sustainability of the facilities they serve, while supporting customers in achieving their own environmental goals.
