(a) tCO
2
e is a metric used to compare the emissions from various GHGs on the basis of their global-warming potential (“GWP”) in comparison to the GWP of carbon dioxide
(“CO
2
”). The main GHG are CO
2
, CH
4
, nitrous oxide and fluorinated gases.
(b) Baseline value chain footprint related to our Science Based Target.
(c) We use the GHG Protocol Corporate Reporting Standard and account for Scope 1 and 2 emissions from operations over which we have control, or the relevant proportion
for jointly controlled arrangements.
(d) Data was calculated using relevant Department for Environment, Food & Rural Affairs (“Defra”) conversion factors, with the exception of Fugitive Emissions, which were
calculated using IPCC Assessment Report 5 emissions factors.
(e) Electricity consumption related to ScottishPower owned EVs is accounted for in ‘Purchased electricity’.
(f) All data reported is based on January to December except for losses data, which is based on figures provided on a regulatory year basis (1April to 31 March).
(g) Scope 2 losses emissions net of our own green generation are presented for information.
(h) Estimated
(i) Scope 2 emissions are presented as both location-based (based on the GB-wide Defra conversion factors) and market-based (taking account of the impact of moving
our own electricity use to a green tariff).
(j) We use the GHG Protocol Corporate Value Chain (Scope 3) Standard for calculating Scope 3 emissions.
(k) Emissions categories reported for the first time this year. Footprint covers full value chain with the exception of emissions related to investments (equivalent to 12,651
tCO
2
e in 2019), which will be included in future years as quantification matures.
(l) 2019 calculation of supply chain emissions used spend multiplied by relevant environmentally extended input-output factors. 2021 and 2022 supply chain emissions
were calculated from an average of the actual emissions of our suppliers.
(m) This category includes upstream emissions (product, fleet, own gas and other fuels), well-to-tank emissions and transmission and distribution related emissions.
(n) Our process for estimating commuting emissions has been updated to include staff survey data for 2021 and 2022.
