The 2019 World Environment Day theme “Beat Air Pollution” was a call to action by the United Nations to combat the challenge of poor air quality.1 While economic growth can result in an increase in air pollution, alternative consumption and production models, knowledge advancements and innovative solutions can successfully reduce emissions to air.2
Mining and mineral processing can contribute to air pollution through processes such as drilling, blasting, crushing, collection and storage, and transportation along the supply chain. Associated emissions to air include particulate matter (e.g., fine and coarse dust that can include minerals and metals) and gases. To maintain a transparent approach to managing these emissions, several governments, including the Canadian and American governments, require companies to monitor and mitigate their impacts on air quality and to disclose their emissions publicly through inventories such as the Toxic Release Inventory in the United States and the National Pollutant Release Inventory in Canada.
Air quality, particularly related to dust, continues to be identified as a key concern by our communities of interest, especially at our steelmaking operations in the Elk Valley and Trail Operations in B.C. and at Carmen de Andacollo Operations in Chile. As air quality issues require close collaboration with local stakeholders, we continue to explore initiatives to improve air quality across our operations.
