TECK REPORTS 2023 SUSTAINABILITY PERFORMANCE

Teck Resources Ltd. today released its annual sustainability report, highlighting the company's performance in 2023 and progress in key areas including climate and nature.

"At Teck, we are committed to responsibly producing the critical minerals the world needs to create a low-carbon future," said Jonathan Price, president and chief executive officer. "Teck is working to further strengthen the company's sustainability performance, including setting a goal of net-zero Scope 1 and Scope 2 emissions across the company's operations by 2050, and being one of the first mining companies to commit to supporting a nature positive future by 2030."

Teck's approach to responsible mining is underpinned by a long-term sustainability strategy, which sets out goals in the areas of health and safety, climate change, circularity, the company's people, water, tailings management, communities and indigenous peoples, and biodiversity and closure.

Teck's 2023 sustainability achievements included:

• Invested $388-million through procurement from indigenous businesses;

• Achieved capacity to treat 77.5 million litres of water per day at the company's steelmaking coal operations as part of the Elk Valley water quality plan;

• Focused on environmental responsibility at the company's expanded Quebrada Blanca (QB) operations, including securing 100-per-cent renewable power, and implementing the first large-scale use of desalinated seawater in place of freshwater for mining in the Tarapaca region of Chile.
