Sustainability Report 2022
Emissions in the atmosphere
DIRECT EMISSIONS (SCOPE 1) AND INDIRECT EMISSIONS FROM IMPORTED ENERGY (SCOPE 2)
The following table summarises the use of fuels for plant and office heating, as well as emissions from refrigerant gas leaks used in refrigerators and air conditioners.
In order to more comprehensively monitor the impact of the Group’s activities on the climate, as of 2022, PSC has added to the calculation of climate-changing emissions generated by the organisation (scope 1) also the indirect emissions from the use of imported energy (scope 2), represented by electricity purchased from the grid.
Sole Oderzo also prepared its first GHG inventory scope 1, 2 and 3, covering the year 2021.

Consolidation approach for emissions
Operational control.
The scope 2 location based emissions consider the most recent data available for domestic electricity production in Italy, Germany, Poland, Slovakia and Brazil as reported by the International Energy Agency.
The scope 2 market based emissions consider the specific electricity mix declared by the energy supplier of each plant. Where not available, the residual mix was considered as reported by AIB 2022. Standards, methodologies, assumptions and/or calculation tools used
- For fuels, invoices
- For refrigerant gases, the FGAS declaration pursuant to Article 16 paragraph 1 of Presidential Decree No. 43 of 27 January 2012, concerning the quantities of refrigerant added in repair activities.
OTHER SIGNIFICANT EMISSIONS
Source of the conversion and emission factors used to calculate energy consumption and emissions:
Ecoinvent 3.8
Data on NOx, SOx, PM and CO are calculated by applying emission factors.
Data on VOCs are analytical and derived from direct measurements.
For all production sites, the amount of emissions in relation to the fuels used was reported according to the following emission factors.
Painting is the production process in which emissions of Volatile Organic Compounds (Vocs) are more consistent. These substances, present in the power coming out from the painting booths are conveyed inside the afterburner chamber, very high efficiency equipment able to cut them from thousands of mg/Nmc to a few units. The VOC abatement process takes place by thermal oxidation (combustion) and the resulting heat is recovered either in the same painting plant - where it is used for the heating of drying furnaces and other purposes - or in other business areas.
In the following table, you can find the details of VOC’s emissions for each plant, where the painting process, at Group level and for the last three years, takes place.
Assumptions:
- Total Assimilation (VOC) to solvent acetone currently present in paints and varnishes
- Net calorific value Lower = 28,5 [Mj/Kg] (from Prontuario dell’Ingegnere, Hoepli, 2010)
- Neglecting diffuse emissions
Direct greenhouse gas emissions decreased, consistent with the reduced consumption of fossil fuels mentioned in the previous chapter.
