ESG Framework

Sustainability-related efforts are integral to our business and consistent with our focus on value creation for our stakeholders. As more fully described in our 2025 Sustainability Report Update and shown below, we have achieved our initial targets or remain on track for achievement of all of our long-term aspirational ESG targets by 2033. Most notably, we’ve delivered a 19% reduction in Scope 1 and 2 emissions from our 2019 baseline, achieving our initial target of 15%(3), and a 35% reduction in emissions intensity. We’ve also demonstrated continuous improvement in employee engagement, with voluntary turnover down over 50% from peak levels in 2022, and driven safety incident rates down to record low levels.

Most notably in 2025, we achieved record safety performance with historic low incident rates following multi-year improvements in both employee retention and safety, with more than 65% of operating locations either posting zero safety-related incidents or achieving year-over-year improvements. Moreover, our Total Recordable Injury Rate remained below industry averages. We have and will continue to raise the bar by evaluating our annual progress towards all of our targets and making forward-looking investments, including state-of-the-art recycling facilities and renewable natural gas facilities at our landfills.
