"Since setting our first-generation environmental goals in 2018, we have significantly reduced our water use, emissions and hazardous waste while continuing to grow as a company. That progress gives us confidence as we pursue our next generation of goals and continue challenging ourselves to make an even greater impact in the years ahead," said Robert J. Pagano, Jr., CEO, President and Chairperson of the Board. "Reflecting on more than a decade of sustainability work, it is rewarding to see how far we have come and the measurable progress our teams have made across the business."

Key accomplishments highlighted in the report include:
