1 These data exclude the energy used by our smaller U.S. offices. Our reporting of our Scope 1 GHG emissions aligns with code NR0102-01 of the Sustainable Accounting Standards Board (SASB) standards for the Oil & Gas – Midstream industry, Non-Renewable Resources sector.
2 Natural gas sales include retail sales to customers and commercial sales (including transportation services) to industrial and other large natural gas users.1 PJ = 1,000,000 GJ. We have converted volume sales data (based on the annual average monthly heating values for gas deliveries) into sales data that are in PJ.
3 Our reporting of our Criteria Air Contaminants aligns with code NR0102-03 of the SASB standards for the Oil & Gas – Midstream industry, Non-Renewable Resources sector.
4 GHG Emissions that Result from Grid Loss: We provide a high-level estimate of the Scope 3 GHG emissions resulting from the loss of electricity during its transmission and distribution (grid loss). The estimate assumes the 2016 national-level percentage grid losses apply for all years. Sources: ECCC NIR (2018) and EPA eGRID (2018).
"N/R" references in this table indicate that emissions were below regulatory reporting thresholds.
