Air

We strive to reduce the emissions intensity and increase the energy efficiency of our operations.

Natural gas is the cleanest fossil fuel, producing about 25 percent less carbon dioxide (CO2) emissions than oil and up to 65 percent less CO2 emissions than coal. Even though natural gas is the cleanest fossil fuel, we continue to direct our attention to further reducing air pollutants from our production methods. We are not just focused on current improvements to air quality. We are constantly looking to the future by advocating for increased natural gas usage in transportation and power generation.

2013 Encana air emissions

Total direct and indirect emissions (CO2e) (1)

Total direct and indirect emissions (CO2e)
  • (1) USA Division air emissions calculation methodology underwent a number of data, process, and methodological improvements in 2012 resulting in a significant decrease in calculated direct emissions from 2011. If the current methodology is applied to the 2011 emission inventory, the revised value for 2012 would be 1,568 103 tonnes CO2e.
  • (2) Indirect emissions decreased due to reductions in electrical grid emission factors used for our BC facilities in 2013.
  • (3) The increase in our U.S. direct greenhouse gas emissions is due to ongoing refinement of our calculation methodology and equipment inventory, as well as operational factors. As well, changes to Global Warming Potentials (GWPs) for methane (CH4) and nitrous oxide (N2O) were mandated by regulatory reporting in 2013. These changes significantly affected our emission inventory, and were retroactively applied to our 2012 inventory to maintain consistency in our inventory and to comply with regulations.
