GHGs - greenhouse gas emissions
MW - megawatt |
| > energy efficiency
Improving energy efficiency is an important means to address GHG emissions. We use a Global Energy Management System, which makes use of international best practices and benchmarking to identify measures that can be taken to improve the energy efficiency of facilities. The system also increases understanding at the project design stage of potential energy-efficiency and GHG-emission-reduction opportunities associated with new projects.
| Since 1994, the overall energy efficiency of our refineries has improved by 16 percent and by four percent during the last five years. Additional investments in energy efficiency occurred in 2006. For example, the design of a new hydrotreater, built at Strathcona refinery as part of the ultra-low sulphur diesel project, incorporated a number of energy efficiency features. By increasing opportunities for heat integration in the new facility, the refinery will reduce fuel consumption, thereby lowering GHG emissions. Numerous smaller improvements in energy efficiency were also made during maintenance turnarounds at the Strathcona and Nanticoke refineries.
Another way we save energy is through cogeneration, a clean and efficient method of producing electricity and steam at the same time. We have cogeneration facilities at Cold Lake and Sarnia, with a combined capacity of 265 MW.

> flaring
Our actions to minimize the flaring of natural gas in our Upstream business also result in fewer GHGs being emitted. Today, virtually all of the solution gas generated at production facilities is recovered (see Air quality for more information).
