Notes: (New) in the table above identifies new key performance indicators added this year.
The asterisks (“*“) in the table above indicate metrics added in recent years and historical data is not available.
(1)
Data is provided from the date of acquisition of the following: Aitken Creek Gas Storage Facility (April 2016) and ITC (October 2016).
(2)
Scope 1 emissions from biofuel are not listed as they are negligible.
(3)
2016 is estimated as 2017 was first year for which data was collected.
(4)
94% of Scope 1 emissions are submitted to a regulatory agency. The remaining 6% is prepared with accordance with regulatory requirements but it is not required to be submitted.
(5)
Excludes line losses from ITC and FortisAlberta. These utilities transmit and deliver electricity only and do not purchase or sell electricity.
(6)
Reflects ITC and FortisAlberta. These utilities transmit and deliver electricity only and do not purchase or sell electricity.
(7)
Reflects Central Hudson and UNS Energy. Emissions reflect customer combustion of the gas transmitted and delivered but not owned by the company.
(8)
It has been assumed that natural gas was used in combustion by customers.
(9)
Represents wholesale purchases and previously reported as Scope 3 emissions.
(10)
UNS Energy had a landfill gas contract that expired in 2019.
(11)
In 2018, a heavy sheen condition developed while pre-trenching activities were taking place at a Central Hudson remediation site. There were no impacts to the local shoreline or downstream water intakes.
(12)
In 2017, a transformer containing trace amounts of PCB developed a leak at FortisAlberta. The site was fully remediated and lessons learned were shared with Fortis utilities.
