By focusing on our back-to-basics priorities, we have reduced lost-time incidents, demonstrating our strong safety-first culture, and achieving our best safety record in over a decade. We also achieved our People Goal of 100,000 volunteer hours, a full year ahead of schedule, and exceeded our original 2025 volunteer goal by an additional 31,000 hours. These achievements reflect our commitment to our associates’ well-being and active engagement in our communities.
In 2024, we evaluated 100% of new products using our sustainability assessments, a substantial improvement from 22% in 2018, our baseline year.
We surpassed our 2025 Renewable Energy Goal in 2022 and continue to explore solutions to expand our use of renewable energy to lower costs and carbon at the same time. Additionally, our focus on thermal drying biosolids from wastewater treatment and eliminating coal ash from steam generation have driven major waste reduction. In 2024, we further optimized our wastewater treatment processes and targeted various waste streams across our manufacturing locations, leading to a decrease in waste intensity
compared to our 2018 baseline.
We are on track to meet our 2030 scope 1-2 reduction target, supported by more than $35 million invested in coal elimination with cogeneration, energy efficiency, increased renewable electricity, and modernizing our manufacturing operations. These investments have produced financial returns of more than 20%. Our efforts to reduce scope 3 emissions continue through supplier engagement, improving product sustainability data, and sourcing lower-carbon materials.
We reaffirm our commitment to the U.N. Global Compact, pledging to uphold the Ten Principles that focus on human rights, labor standards, environmental protection, and anti-corruption. We strive to integrate these principles into our daily operations and strategy, and we actively seek projects that advance these broader developmental goals.
Our goals support the following UN Sustainable Development Goals
