After inputting all data (Figure 24), CO\({}_{2}\) emissions were calculated using the Sustain-SIM model. To verify the accuracy of the model, it is necessary to manually calculate the emission data. The section below presents the manual CO\({}_{2}\) emission calculation for the production process of the trailer reinforcement bracket at VOMAS, Ltd.  
* **Scope 2 Calculations**  
From Table 11 (Activity data: Scope 2), we can extract the necessary data for the calculation of Scope 2 emissions. **Laser Cutting Machine:**  
\[\text{CO}_{2}\text{ emissions = Total energy consumption}\times\text{Utilization}\times\text{ Emission factor} \tag{1}\]  
\[\text{CO}_{2}\text{ emissions = 1.287 kWh}\times 90\%\times 32.68\times 0.352\text{ kg CO}_{2}/\text{kWh}\]  
\[\text{CO}_{2}\text{ emissions = 13.34 kg CO}_{2}\]  
**Smoke and Dust Extractor:**  
\[\text{CO}_{2}\text{ emissions = Total energy consumption}\times\text{Utilization}\times\text{ Emission factor}\]  
\[\text{Operating time = 32.68 h}\]  
\[\text{CO}_{2}\text{ emissions = 7.5 kWh}\times 5.96\%\times 100\%\times 32.68\times 0.352 \text{ kg CO}_{2}/\text{kWh}\]  
\[\text{CO}_{2}\text{ emissions = 5.14 kg CO}_{2}\]  
**Cooler:**  
\[\text{CO}_{2}\text{ emissions = Total energy consumption}\times\text{Utilization}\times\text{ Emission factor}\]  
\[\text{Operating time = 32.68 h}\]  
Figure 24: Data for simulating the impact of solar panels on company CO\({}_{2}\) emissions. CO\({}_{2}\) emissions = 28 kWh \(\times\) 5.96% \(\times\) 100% \(\times\) 32.68 h \(\times\) 0.352 kg CO\({}_{2}\)/kWh  
CO\({}_{2}\) emissions = 19.20 kg CO\({}_{2}\)  
**Press Brake:**  
CO\({}_{2}\) emissions = Total energy consumption \(\times\) Utilization \(\times\) Emission factor  
Operating time = 5000 pcs/200 pcs per hour = 25 h  
CO\({}_{2}\) emissions = 11 kWh \(\times\) 70% \(\times\) 25 h \(\times\) 0.352 kg CO\({}_{2}\)/kWh  
CO\({}_{2}\) emissions = 67.76 kg CO\({}_{2}\)  
**Total Scope 2 Emissions:**  
Total Scope 2 emissions = 13.34 kg CO\({}_{2}\) + 5.14 kg CO\({}_{2}\) + 19.20 kg CO\({}_{2}\) + 67.76 kg CO\({}_{2}\)  
Total monthly Scope 2 CO\({}_{2}\) emissions of VOMAS, s.r.o. are = 105.44 kg CO\({}_{2}\)  
**Scope 1 Calculations**  
From Table 10 (Activity data: Scope 1), we can extract the necessary data for the calculation of Scope 1 emissions. **Stationary Combustion (Natural Gas)**  
CO\({}_{2}\) emissions = Natural gas consumption \(\times\) Emission factor (3)  
403 kWh \(\times\) 0.181234216 kg CO\({}_{2}\)e/kWh = 73.05 kg CO\({}_{2}\)e  
**Mobile Combustion (Petrol)**  
CO\({}_{2}\) emissions = Petrol consumption \(\times\) Emission factor (4)  
540 L \(\times\) 2.328379026 kg CO\({}_{2}\)e/L = 1257.33 kg CO\({}_{2}\)e  
**Total Scope 1 Emissions**  
Total Scope 1 emissions = 73.05 kg CO\({}_{2}\)e + 1257.33 kg CO\({}_{2}\)e  
Total monthly Scope 1 CO\({}_{2}\) emissions of VOMAS, s.r.o. are 1330.38 kg CO\({}_{2}\)e  
**Calculation of the Company's Total Monthly Emissions**  
Scope 1 of the Current Production Process: To quantify the impact of Scope 1 emissions on this specific production process, it is important to consider that these emissions are reported for the entire month, whereas the model production process does not involve continuous monthly production. Therefore, we have decided to treat Scope 1 emissions as linearly distributed with a constant rate throughout the entire working month. Their share in the production process is then quantified based on time dependency. The calculation is performed as follows:  
1. Number of Working Days in the Month (June): 25 days
2. Number of Working Hours per Day: 8 h
3. Production Duration: 32.68 h (4.0849673 working days)
4. Total Number of Working Hours per Month
5. Total hours = Number of working days \(\times\) Number of working hours per day
6.
