Methodology and Restatements

The scope of the 2015 Sustainability Report covers all of the operations managed by Teck and also, where appropriate, key issues at exploration and development projects and at joint venture operations. Data for joint ventures not operated by Teck is not presented unless otherwise stated. Our Duck Pond mine completed operations in June 2015 and we have included its data where relevant. Operations managed by Teck that are covered by this report are:

  • Cardinal River
  • Carmen de Andacollo 
  • Coal Mountain
  • Elkview
  • Fording River
  • Greenhills
  • Highland Valley Copper
  • Line Creek
  • Pend Oreille
  • Quebrada Blanca
  • Red Dog
  • Trail Operations

Joint venture operations not managed by Teck, but covered in some areas of this report are:

  • Antamina
  • Wintering Hills Wind Power Facility 

This report discloses sustainability data for the fiscal year ended as at December 31, 2015. Assessment of material issues continued through the first quarter of 2016. The consolidated data for key indicators can be found in the Measuring our Performance Table.

Unless otherwise stated, we report data for our operations on a 100% ownership basis (e.g., for a 97.5%-owned operation, we report 100% of the data). Data is reported using the metric system and Canadian dollars, unless otherwise stated. 

Where available, we include comparative historical data to demonstrate trends. Historical data is reported based on the scope of the report for the respective year. The scope of the report can change year to year, depending on acquisitions or sales of assets. In our efforts to continually improve and standardize our annual reporting process, the interpretation of data from year to year can often change. Certain comparative amounts for 2014 and 2013 have been reclassified or restated to conform to the presentation adopted for 2015.
