OUR ENVIRONMENT G4-DMA Management approach to greenhouse gas emissions Corresponds with Toronto Hydro’s Material Issue: Air Emissions Toronto Hydro’s approach to managing greenhouse gas (GHG) emissions is to support the City’s goals in their efforts to reduce GHG emissions. In 2015 and 2016, anti-idling technology was evaluated, a facilities consolidation program continued to reduce the square footage per employee of the buildings occupied by Toronto Hydro, and staff were relocated to a new, energy-efficient building from the 6 Monogram Place location. These and other initiatives are described in greater detail below. Toronto Hydro’s GHG emissions are below the reporting threshold for Environment Canada’s National Pollutant Release Inventory (NPRI). The NPRI represents public disclosure of Toronto Hydro’s carbon footprint. G4-EN15 G4-EN16 GHG accounting Toronto Hydro reports GHG emissions through Scope 1 and 2 emissions, as quantified in accordance with national and provincial GHG reporting guidelines, and the GHG Protocol – Corporate Accounting and Reporting Standard. • Scope 1 – Consists of direct emissions from stationary combustion (facilities), mobile combustion (fleet) and fugitive sources (SF6 and refrigerant leaks) • Scope 2 – Contains indirect emissions from the use of purchased electricity (facilities and line losses) Toronto Hydro’s GHG inventory includes all Toronto Hydro-owned and controlled (leased) facilities; however emissions associated with capital work performed by contractors are not included. Scope 3 emissions are also not included in this GHG inventory. The emission factors used to calculate the GHGs are the provincial values4 representative of Ontario’s energy supply mix, and are measured in tonnes of carbon dioxide equivalent emissions per gigawatt-hour (tCO2e). The data from 2014 represents Toronto Hydro’s greenhouse gas base year for comparison purposes. The base year for comparison of GHG emissions was chosen to be 2014 as the methodology for calculating SF6 emissions was changed in 2014. 4 Emission factors published in Environment Canada’s National Inventory Report 1990-2014: Greenhouse Gas Sources and Sinks in Canada 72 TORONTO HYDRO I 2016 CORPORATE RESPONSIBILITY REPORT
