CO2 Report 2022
1. CO2 balance sheet of PRIMES GmbH1.1. Base year
Emissions were collected for the period January 01, 2022 to December 31, 2022.
PRIMES composed its CO2 balance for 2021 for the first time. The year 2021 was characterized by theCovid pandemic, which hardly allowed any travel activities, especially air travel, due to national entry
restrictions for certain countries as well as risk mitigation measures by customers and prospects. Since
2021, a large number of employees has not been present in the company due to the use of a flexibleworking time model, which can have an impact on CO2 emissions. However, this is not quantified in thisreport.
1.2. Location
Pfungstadt (Germany).
PRIMES has 2 company buildings at this location. Both are included in the calculation.
1.3. Scope
This CO2 report considers emissions from the following sources: Heating Electricity consumption (subtracting electricity generated by own solar systems)
 Business trips
 Company cars
Cooling for the lasers and heating and cooling of the buildings are largely provided by two cisterns outside
the buildings in combination with a heat pump and concrete core activation of the ceilings. The remaining
heating requirements are covered by gas heating. Consumption for additional air-conditioning units isincluded as electricity consumption.
Emissions from the upstream and downstream plant supply chain are not included in the balance sheet,with the exception of business trips, as PRIMES has no direct influence on them.
1.4. Data sources
The data for the preparation of the balance sheet was determined or estimated from the gas and electricity
invoices, bookings of business trips and mileage of the company cars.

3. Summary
We compensate about 61 % of the emissions with the own electricity generation of the solar plants.
PRIMES GmbH had about 130 employees in 2022. We have an emission of less than 450 kg CO2/year
per employee. On average, each German emits over 8 500 kg of CO2 per year.
The CO2 balance for 2022 results in a higher value for CO2 emissions compared with the previous year.
The higher value can be explained by external factors at global level. In 2022, the restrictions caused by
the Covid pandemic came to an end thanks to the availability of vaccines and higher immunity in thepopulation. As a result, national business and professional life almost returned to normal. At theinternational level, travel restrictions were still in place, but overall travel increased again in 2022. The
presence in national and international trade fairs still did not match the pre-pandemic level but normalized
for the most part.
It is to be expected that the CO2 emission level will continue to rise and that we will only have arepresentative base year from 2024/2025 onwards on which we can look at the effect of reduction
measures.

4. Targets for 2023
 Reduction of CO2 emissions caused by heating by reducing gas consumption by approximately
10 %.
 Reduction of CO2 emissions caused by electricity consumption by reducing electricity consumption
by approximately 3 %.
