Environmental

Before mining, we conduct thorough comprehensive baseline studies of local ecosystems, geology, water, and land use to develop the detailed assessments required for mine permit approvals. These assessments also guide our mine planning process to minimize impacts, respect critical habitats, and achieve cost-effective reclamation that supports biodiversity outcomes post-mining.

Prior to the development of any above-ground storage facility, a comprehensive options analysis is undertaken. This evaluation addresses life-of-mine storage needs, disposal methods, potential environmental and community impacts, operational management considerations, and closure obligations. The management of mineral waste in our tailings impoundments plays a critical role in minimizing the impact of mining for communities, the environment, and our operations.

Where feasible, our preferred strategy is to store mineral waste below ground level within available mining voids. If above ground storage is necessary, detailed designs are developed in compliance with both local and federal regulations. Throughout construction and operation of each impoundment, regular assessments by qualified, independent engineers ensure conformity with design specifications, monitoring regimes, and maintenance protocols, consistent with Peabody’s Coal Waste Containment standard.

We regularly assess the effectiveness of our reclamation practices, track our progress at each site, and prioritize progressive reclamation through our incentive compensation metrics. To ensure regulatory compliance is achieved and Peabody’s standards are implemented, relevant staff receive training on permit conditions and site practices controls. Where applicable, Peabody also engages with our stakeholders, including Traditional Owners and Indigenous groups, to incorporate their knowledge and perspective into the reclamation practice that will shape post-mine land use.

Since the 1960s, Peabody has served as a leader in reclamation performance and industry-leading practices, and that proud history continues today. Our dedicated reclamation staff are leaders in the science and methodology that have supported our performance. By investing in ongoing and progressive land restoration, we have enabled new uses and redevelopment of former mine sites, including opportunities for renewable energy projects on reclaimed land, recreational areas for conservation, and housing developments in mining communities.

Successful land restoration is a metric within Peabody’s executive compensation program, with a target of reclaiming as much, or more, land than we disturb annually. This approach balances cost-optimized operational excellence and our commitment to minimizing environmental impacts from our mines.

Peabody has established an annual target to restore one acre of mined land for every acre disturbed. In 2025, we surpassed this benchmark by grading 2,629 acres and revegetating 3,269 acres of mined land, equivalent to 1.6 acres graded and 2.0 acres revegetated for every acre affected by mining. Our progressive land practices also resulted in $45.1 million in bond releases and contributed to revitalizing wildlife habitats, rangelands, forests, prime farmland, grazing areas, and wetlands.
