Glencore - Sudbury Integrated Nickel Operations

Glencore’s Sudbury Integrated Nickel Operations (Sudbury INO) activities include exploration, Fraser Mine, Nickel Rim South Mine, Strathcona Mill and Sudbury Smelter. The company has been mining nickel copper ores in the Sudbury area of northern Ontario Canada, since 1928. The facilities are spread throughout a 60km-long oval shaped geological formation known as the Sudbury Basin.

Current Milestone
Onboarding: Members learn about the program, and identify immediate sustainability goals and support needs.
Developing: Members gather data about sustainability performance, set a baseline year, and prepare to report on metrics.
Reporting: Members measure and publicly report on sustainability metrics, and prepare detailed action plans.
Targeting: Members set a public sustainability target and implement action plans.

Total Emissions: An inventory of all sources of greenhouse gas emissions is the total amount of Carbon Dioxide Equivalent produced over the entire business operation, compiled to ISO 14064-1 standard. For comparison, 5.23 Tonnes of CO2 are emitted by the average passenger vehicle in one year.

Tonnes of CO2 Emmissions  

Scope 1 Emissions: These emissions come from direct release of greenhouse gases, primarily from the consumption of fossil fuels from space heating or vehicle use.

  2016 Scope 1: Energy Direct

Scope 2 Emissions: Electricity consumption requires generation. A share of Ontario’s energy grid comes from fossil fuel generation, and this share is reflected in Scope 2, or “energy indirect” emissions.

Sudbury INO has continuously worked to reduce their energy and greenhouse gas (GHG) emissions through several upgrades within their facilities. Some of these include replacing the SO2 Blower Variable Speed Fan, replacing Converter #8 and also switching to Ventilation on Demand (VOD).

Established an ISO 14001 Green Team since the early 2000s comprised of environmental, operations and management personnel. They work towards achieving continual improvement, pollution prevention and regulatory compliance. Sudbury INO is also part of the Environmental Monitoring Team*, Wahnapitae First Nation Environmental Working Group, VETAC Regreening Advisory Panel, Falconbridge Citizens Committee and Clean Air Sudbury.

Sudbury INO has had some great successes for 2015, including maintaining ISO 14001 certification (an international standard that specifies requirements for an effective environmental management system) on all sites for over 10 years, regreening efforts in support of VETAC (e.g. in 2015 VETAC planted ~70,000 trees), maintained high water quality, carried out capacity building with Wahnapitae First Nation (now has an environmental consulting service group), completed phase one of the Process Gas project (compliance with Reg. 419 with respect to SO2 and metals emissions).
