* Indicators marked with „*” was subject of a assurance engagement by an independent auditor.
Consumption of selected raw materials, of key importance due to the type of activities:
Consumption of raw materials as reuse
Fuel and electricity consumption
* all values refer to internal consumption within the organisation (Scope 1, Scope 2)
** calculations take into account all energy media mentioned in the table, but the relatively small impact of Budimex Nieruchomości and Mostostal Kraków was not taken into account
Purchase of energy from renewable sources
[305-1], [305-2], [305-4]
**relatively small impact of Budimex Nieruchomości and Mostostal Kraków was not taken into account
Operations performed within valuable natural areas or in their proximity
Air emissions of pollutants, main sources (in kg/year)
 Due to the necessity of using another range of data sorting filters and harmonising measurement units, the selected values for raw materials consumption for 2015 and 2016 have been changed.
 The energy efficiency index for 2016 was adjusted by the adjusted value of thermal energy consumption.
 Budimex SA treats all purchased energy as direct consumption. Ass fuels are consumed by machines and equipment owned by Budimex. Despite the fact that part of the energy is used by subcontractors, it is also recognised as direct consumption, since no mechanisms of dividing electricity consumed separately by Budimex and its subcontractors were introduced.
 No biogenic CO2 emission took place in Budimex SA, whether within Scope 1 or Scope 2.
 Estimates obtained using the common methodology applied in the Ferrovial Group, based on the GHG Protocol and actual consumption of basic fuels and electricity.
 Calculating error correction.
 Data verified with avoided emissions from the purchase of renewable energy.
