Update of emission factors and the display in the PDF report

When creating a new report, the following updates have been implemented:

• DEFRA emission factors: Updated to 2025

• CO2 BAFA emission factors: Updated to 2025

• Transporter / Van (< 3.5 t): Adjustment of the emission factor from a pure diesel vehicle to a mixed vehicle, covering both diesel and petrol

• Heating oil: Updated from fuel oil to gas oil, better reflecting its common use in diesel engines and heating systems

• Heating oil and natural gas: Conversion basis changed from gross calorific value (GCV) to net calorific value (NCV), ensuring that only the effectively usable energy, excluding the energy bound in water vapor, is considered

• Conversion factor E1-5: Adjusted for heating oil, natural gas, and additionally wood pellets, now based on the net calorific value

• PDF transparency: The exported PDF report now includes not only the data source but also the corresponding reference year of the emission factor
