All of our customers’_{CO2 emissions} resulting from gas combustion must be offset by_CO2 reductions achieved elsewhere. This ensures that greenhouse gas emissions remain neutral on a global scale._CO2 reductions are achieved through climate protection projects that involve, for example, sustainable energy generation using biomass, wind, or hydropower, or reforestation initiatives. The amount of_CO2 saved in these projects is verified by independent and recognized auditors and recorded in national or international registries. By investing in these projects, portions of the saved_{CO2 credits} can be purchased and used for offsetting.

To offset our customers’_{CO2 emissions}, we make targeted investments in selected projects that have prevented greenhouse gas emissions and are therefore eligible for offset. In recent years, we have purchased_{CO2 credits} from the following climate protection projects.

The total volume of natural gas sold is converted into energy units, measured in kWh. An emission factor is used to calculate CO2 emissions. This factor indicates how much CO2 is released per unit of energy. According to the Allocation Ordinance 2020 (ZuV 2020); Section 2(29)(c), the emission factor for natural gas (H & L) is 201.6 g CO2/kWh. This means that for every kWh of energy generated by natural gas, 201.6 g of CO2 are released

The calculated energy amount in kWh is multiplied by the corresponding emission factor (201.6 g CO2/kWh) . The result is then multiplied by the conversion factor 0.903, since the final calorific value corresponds to only 90.3% of the nominal calorific value of natural gas. The result is divided by 1,000,000 to determine the CO2 emissions in tons.
