Glencore Halts $300M Quebec Smelter Investment to Cut Emissions
Glencore Canada has announced the suspension of its $300 million investment aimed at reducing emissions at the Horne Smelter in Rouyn-Noranda, Quebec. This decision follows the province’s inability to reach a satisfactory agreement with the Swiss multinational firm.
Investment for Emission Reduction
Initially, Glencore planned a nearly $1 billion investment to cut arsenic emissions at the smelter and modernize its facilities. This initiative was in line with Quebec government targets, which stipulate an allowable annual average of 15 nanograms of arsenic per cubic meter (ng/m³) in ambient air, measured at the nearest sampling station to the smelter.
Company’s Announcement
In a recent press release, Glencore expressed that it would be “irresponsible” to proceed with investments without assurance of the smelter’s long-term operational viability. Additionally, plans to invest at the CCR Refinery in Montreal will also be curtailed in the medium term.
Future Compliance Challenges
Starting in March 2027, the Horne Smelter is projected to be unable to comply with its permit terms, putting the facility at risk of closure. Glencore has continuously set forth two essential conditions for the Quebec government: adjust the emissions reduction plan to a realistic timeline and ensure stable regulatory conditions, including maintaining the 15 ng/m³ arsenic emissions target during the next permit period.
Operational History and Emissions Statistics
- Established: 1927
- Average Arsenic Levels (March 16, 2023 – March 15, 2024): 45 ng/m³
- Reduction: 40% decrease from the previous year
Since summer 2025, Glencore has made multiple efforts in collaboration with the Quebec government to ensure operational sustainability. However, the company claims necessary conditions for continued operation have not been satisfactorily met.
Emissions Controversy
The Horne Smelter has faced significant backlash concerning its emissions. A class-action lawsuit has been authorized by the Quebec Superior Court, filed by two residents of Rouyn-Noranda against both Glencore and the provincial government. The plaintiffs allege that the smelter has breached Quebec’s environmental standards, leading to disturbances in the neighborhood. They further accuse the provincial government of failing to adequately supervise Glencore’s operations.
Glencore’s chief of operations for custom metallurgical assets, Marc Bédard, emphasized the importance of job protection and operational continuity for the company in light of these developments. The situation remains critical as negotiations with the Quebec government continue to evolve.
