Question Id: E1-6_21
Location-based Scope 2 emissions are calculated by recording and consolidating all consumption of purchased energy (electricity, district heat, and district cooling) under the operational control of HOCHTIEF and its consolidated companies and obtaining the GHG emissions by applying emission factors from centrally provided official databases (IEA). Market-based Scope 2 emissions are calculated by recording and consolidating, at Group level, all consumption of purchased energy (electricity, district heat, and district cooling) under the operational control of HOCHTIEF and its consolidated companies. The emissions are calculated using the hierarchy of available emission factors. This consists of the following relevance levels, from top to bottom: 1. Market-/supplier-specific: HOCHTIEF Group consolidated companies can enter market-/supplier-specific emission factors into the central database. These are then used to calculate market-based Scope 2 emissions. Where companies do not have any market-/supplier-specific emission factors, level 2 residual mix emission factors (Residual Mixes AIB) are used. These are likewise contained in the central database. Failing level 1 and level 2, location-based calculation is used as level 3. Data on green electricity is collected and included separately.
