GHG Programs

Greenhouse Gas Management Systems

Specific best practices on energy management systems can be found in the Mining Association of Canada’s Toward Sustainable Mining website. Our continued reporting against these standards is provided in the detailed Operations sustainability summary reports for Trail, Highland Valley Copper and the Hemlo Operations.

Greenhouse Gas Emissions

Teck’s direct GHG emissions (as CO2 equivalent) increased to 1,602 kilotonnes in 2007, largely as a result of including emissions from EVCP (on a 52% basis). Emissions excluding EVCP totaled 778 kilotonnes (kt) compared to 728 kt in 2006. Key increases in 2007 were a consequence of the first year of operation for Lennard Shelf and a rise in emissions at HVC due to additional truck and shovel use for the mine life extension work noted above.

Note that our reported direct GHG emissions now include estimated emissions associated with the Waneta Dam hydroelectric facility which we own. Approximately 1900 GWh of energy from this facility is used at Trail Operations, while 900 GWh is sold to the export market. Estimated emissions from the dam are reported separately from those for Trail Operation in order to ensure that comparisons with other zinc production facilities, which do not typically own the facility which supplies their electrical power, can be made on a more consistent basis. At present, the emissions factor we use for this hydro facility is based on electricity usage for the province of B.C. (0.02 kg CO2e / kWh). We believe that actual emissions from this hydro facility are considerably lower, and are working towards developing a more accurate emissions factor.

It should also be noted that direct emission results for previous years at Trail have been restated based on slightly revised methane and nitrous oxide emission factors associated with the use of coal and coke.

We also track our indirect GHG emissions associated with electricity use; 2007 estimations are 162 kt, or approximately one tenth of our direct emissions. Our indirect emissions are relatively small as many of our Operations are in regions which obtain a significant proportion of their electricity from hydro generation, such as British Columbia and Washington State.

Teck also reports on GHG emissions and energy consumption in the Mining Association of Canada’s Annual Progress Report (see www.mining.ca). Reports on our facilities emitting more than 100 kt CO2e/annum under Canada Federal requirements are available at www.ghgreporting.gc.ca.

Transportation Indirect Emissions

Our transportation emission impacts result from three principle activities: transportation on-site, receiving materials from suppliers, and distributing products to market. Teck has not thoroughly evaluated indirect transport emissions in the past other than a preliminary assessment of distributing products from the Highland Valley Copper mine in 2006, which indicated that the largest contributor to CO2 emissions is from marine vessels as opposed to truck and rail activities.
