As an energy intensive business, our greenhouse gas emissions are comprised of a wide range of direct and indirect emissions sources, including mobile equipment, building heating, iron ore indurating furnaces, a wholly owned power plant, and via the purchase of grid electrical power.

Our program has focused on the following:

  • Migrating to cleaner iron ore indurating furnace fuels, i.e. natural gas vs. coal
  • Implementing energy efficiency projects throughout the process
  • Conserving heat within the operating facilities during winter months
  • Replacing old equipment and motors with modern, efficient components and controls
  • Supporting our electrical provider’s significant efforts to move towards clean, renewable energy sources vs. fossil fuels (electrical provider in Minnesota is expected to achieve 44% renewable energy production by 2026)
  • Negotiating new power contracts with our suppliers to reduce cost and environmental impacts to the regions where we operate
  • Developing products for our customers to reduce steelmaking total greenhouse gas lifecycle emissions

Some additional information from these efforts is provided below.

Cliffs’ involvement in stabilizing the energy supply in Michigan’s Upper Peninsula facilitated the transition of the 350-megawatt coal-fueled Presque Isle Power Plant to new natural gas-generating stations with a combined output capacity of 183 megawatts. The transition, completed in Spring 2019, will result in an approximately 75% reduction in Scope 2 carbon dioxide emissions.

Two coal fired power plants will be replaced with renewable energy from the grid and cleaner, more efficient natural gas power generation.

Our procurement of renewable energy in Michigan and Minnesota will increase substantially over the coming years, to approximately 40-45% by 2025.

In the last three years, two of our facilities have implemented numerous energy efficiency projects that have resulted in 67,000,000 kWh savings (enough for 2,100 houses over three years).
