Senior Research Associate at UMass Lowell

Mark Rossi is a senior research associate at the Lowell Center for Sustainable Production (LCSP). He is a leader in creating innovative solutions to the challenges of hazardous chemicals in products, manufacturing operations, and supply chains.

Rossi led and co-created solutions for safer alternatives to chemical pollution from 2004-2025 as the co-director and then executive director at the non-profit environmental organization, Clean Production Action. Recognizing that no single organization can solve the complex problems of chemical pollution, he founded in 2006 the multi-stakeholder collaboration, BizNGO Working Group for Safer Chemicals and Sustainable Materials, to bring together business leaders, regulators, and environmentalists to co-create safer solutions.

In the search for reducing the complexity of finding safer alternatives to hazardous chemicals, Rossi led the development of and co-created the chemical hazard assessment method, GreenScreen® for Safer Chemicals in 2007, and the ecolabel standard, GreenScreen Certified® in 2017. Today, companies across the globe use GreenScreen to select safer chemicals and products in the building, electronics, retail, textile, health care, firefighting foam, apparel, and food service ware sectors. Seeing the need for a metric to track progress away from hazardous chemicals to safer solutions, he co-founded the Chemical Footprint Project (CFP) in 2014. The concept of chemical footprinting as defined by CFP is now integrated into the international Global Framework on Chemicals. With LCSP team members he has co-authored many research reports, including: Chemical Footprint Project annual reports (2016-2020); Alternatives to Methylene Chloride in Paint and Varnish Strippers (2015); Guidelines for Sustainable Plastics (2009); and Alternatives Assessment Framework of the Lowell Center for Sustainable Production (2006).
