Carbon Capture, Utilization and Storage: A suite of technologies that captures CO2 from facilities, including industrial or power applications, or directly from the atmosphere. Once the CO2 is captured, it is then compressed and transported to be permanently stored in geological formations underground (e.g., saline aquifers, oil reservoirs), or used to create products such as concrete and low-carbon synthetic fuels. CCUS technologies can deliver ‘negative emissions’ by removing CO2 from the air (direct-air-capture) or from biomass-based energy and storing the CO2.1

This may include claims of negative direct impacts, failure to meet obligations or expectations, or lack of fair treatment or process. Teck uses a risk management consequence matrix from Level 1 to 5 to determine grievance severity, which includes environmental, safety, community, reputational, legal and financial aspects. A grievance becomes a dispute when it cannot be resolved jointly within a two-year period and is reassessed as a Level 4 or 5 severity on the risk management consequence matrix.

(Note: a supplier who in the course of providing goods also provides ancillary services (e.g., delivery of goods] is nevertheless considered a supplier).

Supply Chain: A network between a company and its suppliers to produce and distribute a specific product to the final buyer. This network includes different activities, people, entities, information, and resources. The supply chain also represents the steps it takes to get the product or service from its original state to the customer. The supply chain lays out all aspects of the production process, including the activities involved at each stage, information that is being communicated, natural resources that are transformed into useful materials, human resources, and other components that go into the finished product or service.

Total Recordable Injury Frequency (TRIF): A key measure of safety performance that demonstrates the total number of recordable injuries per 200,000 hours worked. Recordable injuries include fatalities, lost-time injuries and injuries requiring medical aid. The types of incidents not included in the TRIF calculation include first aid injuries, high-potential incidents, non-injury property damage, and non-injury mobile equipment events. TRIF is calculated as follows: TRIF = (number of medical aid injuries + number of lost-time injuries + number of fatal injuries x 200,000) divided by total number of hours worked. The factor of 200,000 is derived from the average number of hours worked by 100 people in a one-year period (50 working weeks x 40 hours per week x 100 people). This factor is frequently used in North America.
