Clean Harbors Issues 2025 Sustainability Supplement; Achieves 2030 Recycling Goal Ahead of Schedule

Clean Harbors, Inc. (“Clean Harbors”) (NYSE: CLH), the leading provider of environmental and industrial services throughout North America, today published its 2025 Sustainability Supplement, which provides annual data related to its 2024 environmental, social and governance efforts and an update on progress toward its sustainability goals. Clean Harbors recycled 1.9 million metric tons of materials in 2024, accomplishing its recycling goal far in advance of its 2030 target date.

“Clean Harbors continues to provide our customers with environmentally responsible and sustainable solutions for today’s rapidly changing world,” said Eric Gerstenberg, Co-Chief Executive Officer. “In 2024, we recycled more materials than ever before, satisfying Our Environment goal to increase our overall recycling 25% on a combined basis from our 2019 baseline. We achieved this milestone well in advance of 2030 because of the quality of our industry-leading team, our commitment to innovation, and the considerable investments we’ve made in our technologically advanced recycling capabilities.”

The 2025 supplemental report, which is available at www.cleanharbors.com/about-us/sustainability, highlights the suite of sustainable solutions Clean Harbors offers its customers as well as its own sustainability efforts to reduce the environmental footprint of its operations.
