Cameco Corporation is one of the world’s largest providers of uranium fuel. Nuclear energy plants around the world use its uranium products to generate one of the cleanest sources of electricity available today. Cameco is committed to delivering its products safely and responsibly. Sustainable development principles and practices are integrated at each level of Cameco’s organization, from overall corporate strategy to individual employee practice in day-to-day operations.

Cameco’s corporate objectives are set out under four measures of success: a safe, healthy and rewarding workplace; a clean environment; supportive communities; and outstanding financial performance.

SAFE, HEALTHY, REWARDING WORKPLACE

Cameco is committed to living a strong safety culture, while looking to continually improve. As a result of this commitment, the company has a long history of strong safety performance at its operations and across the organization.

2018 Highlights:

• Best safety performance in the history of the company as measured by Total Recordable Incident Rate (TRIR) and Lost Time Incident Rate. However, our TRIR performance did not meet the improvement target set for 2018; therefore, our efforts toward continuous improvement in this area remain a focus moving forward.
• Several operations reached significant safety milestones, including the Blind River Refinery and the Crow Butte Operation passing 12 and 11 years respectively without a lost-time incident and several other facilities continued to increase their record of days without a lost-time accident.
• Continued low average dose of radiation to workers, including the Cigar Lake Operation as it sustained production at licensed capacity.
• Continued improvement of safety systems and performance for support groups, such as corporate facilities.

CLEAN ENVIRONMENT

Cameco is committed to being a leading environmental performer. This is done by keeping risks as low as reasonably achievable and looking for opportunities to move beyond regulatory requirements. Progress is tracked by monitoring the air, water and land near the company’s operations, and by measuring the amount of energy used and the amount of waste generated. This information helps Cameco identify opportunities to improve.

2018 Highlights:

• As part of Vision in Motion, we began shipping contaminated soil and legacy low-level radiative waste stored at the Port Hope Conversion Facility to the long-term waste management facility.
• Remained a top performer under Canada’s Fisheries Act Metal and Diamond Mining Effluent Regulations with effluent performance well below regulatory limits.
• Sustained Cigar Lake at full production without exceeding an environmental limit or having a significant environmental incident.
• Continued efforts to reduce low-level radioactive waste stored at our Fuel Services Division.
• Implemented Canadian Standards Association (CSA) Waste Management Standards at our Fuel Services Division facilities.
• Continued efforts to systematically improve energy conservation and efficiency at both our Fuel Services Division and Saskatchewan facilities.
• Continued industry-leading research developing enhanced groundwater restoration techniques that can be applied at our US in-situ recovery operations.

SUPPORTIVE COMMUNITIES

Gaining the trust and support of our communities, our Indigenous partners, and governments is necessary to sustain our business. We earn support and trust through excellent safety and environmental performance, by proactively engaging our stakeholders in an open and transparent way, and by making a difference in communities wherever we operate. We are a leading employer of Indigenous peoples in Canada, and a five-time Gold award winner through the Progressive Aboriginal Relations program as judged by the Canadian Council for Aboriginal Business. Since 2004, we have procured nearly $3.8 billion in services from local suppliers in northern Saskatchewan. These efforts are critical to obtaining and maintaining the necessary regulatory approvals.

2018 Highlights:

• Over $120 million in procurement from locally owned northern Saskatchewan companies (89% of total).
• On December 31, in northern Saskatchewan, 319 of our employees were Residents of Saskatchewan’s North (RSN) (49.7% of total), compared to 603 RSN employees at the end of 2017 (49.6% of total). While the number of employees declined as a result of the suspension of production at our McArthur River/Key Lake operations for an indeterminate duration, we maintained the proportion of RSN.
• Corporate Knights ranked Cameco as one of Canada’s top five Corporate Citizens in 2018.

TSM PERFORMANCE

Due to difficult uranium market conditions, Cameco has undergone a number of changes to its operations and support functions in recent years, including the suspension of production at McArthur River and Key Lake in early 2018, and the suspension of production at Rabbit Lake and curtailment of US production in 2016. Nonetheless, Cameco remains committed to effective management systems, which is reflected in its strong TSM scores.

Aboriginal and Community Outreach

Cameco’s commitment to meaningful community engagement is reflected in the TSM results for its facilities. Cigar Lake, Key Lake and McArthur River achieved Level AAA performance for all indicators of the Aboriginal and Community Outreach Protocol.

Crisis Management and Communications Planning

Cameco’s corporate office and participating facilities met all of the criteria of the Crisis Management and Communications Planning Protocol.

Safety and Health

Cameco continued to demonstrate high levels of performance in the area of safety and health. Cigar Lake, Key Lake and McArthur River achieved at least Level AA performance for all of the TSM Safety and Health Protocol’s five indicators.

Tailings Management

Cameco has maintained Level A performance in tailings management for its Key Lake Operation. The company has been engaged in MAC’s review of the TSM Tailings Management Protocol and is working to implement the new criteria at its facilities.

Biodiversity Conservation Management

Cigar Lake, Key Lake and McArthur River maintained strong performance in biodiversity conservation management as well, with at least Level AA performance for all three of the Protocol’s indicators.

Energy Use and GHG Emissions Management

The area of energy use and GHG emissions management represents an opportunity for improvement for Cameco’s facilities. The company is working to enhance its energy management and expects performance for this Protocol to improve in the coming years.
