Emissions in the atmosphere
DIRECT EMISSIONS (SCOPE 1)
The table below shows the use of fuels for plants and heating for offices, as well as emissions deriving from the refrigerant gas losses in refrigerators and air conditioners.
Source of GWP factors
Regarding GWP metrics for all substances with altering climate effect, Chapter 8 (Anthropogenic and Natural Radiative Forcing) of the Climate Change Report 2013: The Physical Science Basis was used as a source. Contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change, published by Cambridge University Press.

- Density and LHV (PCI): ENEA, Testing an integrated system fuel processor/polymer electrolyte fuel cell LPG fuelled for stationary power generation.
NOx, SOx, PM and CO are calculated by applying the emission factors mentioned above. VOC data are analytics and obtained from direct measurements.
For all the plants the amount of emissions, compared to the fuels used according to the following emission factors, has been reported
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. When reading the reduction in emissions, it is necessary to consider the reduction in the number of companies where this processing takes place, which in 2021 went from 6 to 5 and the fact that Ferentino carried out more frequent active carbon changes in 2021, with a consequent greater efficiency in the containment of emissions.
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
KPI for monitoring the Group’s performance: greenhouse gas emissions
The value of direct greenhouse gas emissions (Scope 1) per unit of generated value detects some changes during the three-year period, with a slight increase in 2020, compared to the previous year, due to a reduction in the generated value.
