Energy Use and Greenhouse Gas

As users of fossil fuels to extract and transport ore and electricity to run processing plants, Hudbay operations track energy consumption and associated greenhouse gas (GHG) emissions. We strive to reduce our impact by minimizing energy use and, where possible, reducing the carbon intensity of our operations.

In Manitoba, we set annual energy and GHG reduction objectives, which we strive to achieve through energy savings and CIPO projects. We also closely monitor the regulatory climate to guide our actions.

Although we had intended to establish a GHG baseline for Peru in 2014, we realized that this was premature and now plan to establish a baseline once the facility reaches steady-state operation.

Because Rosemont is in the permitting phase, there are no management plans associated with GHG or fuel use at this time. Most GHG generation is directly attributable to the drilling program fuel use, with a small portion created by light vehicles used for site and ranch activities. However, we have a demonstration solar power site at the field office that generates credits under the Tucson Electric Power program. We are testing various solar technologies to determine their viability for our future use and to provide feedback to the technology providers.

2014 Performance

  • In Manitoba, unusually cold temperatures increased heating needs, so we did not achieve our self-identified target of a 1% reduction in GHG emissions from our 2012 base. As a result of climate-related conditions, total energy use rose by 9% from the base year, with propane use up 18% and electricity up 8%, while diesel and gas consumption was unchanged. Energy intensity rose by 18% from the 2012 base year due to lower metal production.
  • Constancia energy use and GHG emissions rose significantly in 2014 as a result of increased use of diesel fuel for construction activities (mobile equipment and generators) and the start of operations at the Constancia pit and the processing plant.
