GRI G4 EN8

Includes intercepted water. Cameco withdraws water from surface water, collects groundwater, and withdraws water from municipal water utilities in the areas where we operate. Rainwater that comes into contact with our operations is collected and stored, which is reflected in our water withdrawal volumes. Cameco does not withdraw wastewater directly from other organizations. Water withdrawal from our exploration activities is not included. Cameco is currently evaluating how this indicator is reported to align with the new GRI standards and plans to update the way water withdrawal is reported in future ESG reports.

EM-MM-140a.1

Fresh water defined as water with an average total dissolved solids (TDS) less or equal to 1,000 mg/L for the purpose of this indicator. Areas of High or Extremely High Baseline Water Stress were identified using the World Resources Institute Aqueduct tool. Cameco's North Butte operation is classified in an area of high water stress (3-4). Cameco withdraws fresh water from a drinking water aquifer at North Butte for use in firewater suppression systems, bathrooms, and sinks within surface buildings. The quantity of water withdrawn is < 5,000 m3 annually. This is such a small proportion of total water withdrawn that it is not measurable within the corporate total.

Non-mineral wastes

Non-mineral waste does not include solid waste generated as tailings, water treatment sludge and slime, or waste rock. Non-mineral waste does include mineral processing waste. Cameco does not generate intermediate or high-level radioactive waste. The total amount of low-level radioactive, non-hazardous, and hazardous waste generated in each category is separated and presented by disposal method: diverted, landfilled, or stored on site. Diverted materials include those that are recycled, reused, repurposed, or reprocessed. We separate waste into these disposal categories using internal tracking systems that track the inventory of waste on site and the transfer of waste off site. The amount of waste transferred off site is confirmed through information provided by the receiving organization.

GHG emissions/energy use

Cameco’s scope 1 greenhouse gas (GHG) emissions are presented as tonnes of carbon dioxide equivalents (CO2e). CO2e is used to compare the emissions from various GHG sources based on their global warming potential (GWP). Cameco adopted the GWPs published by Environment and Climate Change Canada (ECCC) and the United States Environmental Protection Agency (US EPA), which reference the GWPs stated in the International Panel on Climate Change’s Fourth Assessment Report. Cameco’s significant sources of direct GHG emissions include those generated by the consumption of fuel from non-renewable sources and industrial processes. Emission factors that are country- and fuel-specific are used to convert the fossil fuels consumed to GHG emissions in CO2e. For our Canadian operations, we have used emission factors published by ECCC through the Greenhouse Gas Reporting Program. For our US operations, we use the emission factors published by the US EPA in the most recent Emission Factors for Greenhouse Gas Inventories document. 

Cameco’s indirect (Scope 2) GHG emissions are presented as tonnes of CO2e. CO2e is used to compare the emissions from various GHG sources based on their GWP. Cameco adopted the GWPs published by ECCC and the US EPA, which reference the GWPs stated in the International Panel on Climate Change’s Fourth Assessment Report. Indirect GHG emissions are calculated by applying a utility- or region-specific emission factor to the amount of electricity purchased from that area, which is determined through utility invoices.

Total energy consumed GJ 3,261,156 3,189,800 3,222,286 EM-MM-130a.1 Cameco’s energy consumption includes energy consumed as fuel from non-renewable sources and energy consumed as electricity. Energy consumed as fuel from non-renewable sources is calculated by applying a fuel- and region-specific energy content factor to the consumed volume of non-renewable energy sources at Cameco’s operations. These energy sources include propane, natural gas, diesel and gasoline. Cameco does not utilize renewable energy sources directly. Energy consumed as electricity is calculated by applying a conversion factor of 0.0036 gigajoules per kilowatt hour (GJ/kWh) to the raw electricity consumption. Cameco does not sell energy as electricity, heating, cooling, or steam.

Air quality

Air emissions are reported for operated facilities in Canada only. Air emissions from our in situ recovery operations in the US are not material for this indicator and are not included. Air emissions of NOx, SO2, CO, VOCs, PM, PM10, PM2.5 and NH3 are calculated using the guidance provided by Environment and Climate Change Canada through the National Pollutant Release Inventory. The total air emissions for these constituents include air emissions released through point sources such as process stacks, storage and handling, fugitive emissions, and as a result of road dust. Air emissions of uranium and Hydrogen Fluoride include air emissions released through point sources.

Public support

Reported data on public support is taken directly from polling Cameco undertakes in the various regions in which we operate. Data collection is undertaken by marketing research experts using industry-accepted methodology aimed at collecting unbiased opinions of community support. Accuracy of individual polls varies by region and from year to year based on individual sample sizes. It is important to note that polling questions in Ontario are framed in terms of support for Cameco operations specifically while other regions are asked about their support of the uranium industry more broadly.
