The GHG balance (CO2 balance) of the Friedr. Lohmann GmbH takes all three GHG Protocol scopes into account. We prepare our carbon footprint statement according to the GHG Protocol (Greenhouse Gas Protocol). This includes the documentation and evaluation of Scope 1, 2, and 3 based on a calculation of costs (relevance) and other key figures.
Particular attention is paid to the definitions of the system boundaries. We completely document all three scopes according to the “cradle to gate” approach (completeness). This applies in particular to Scope 3, which we evaluate in great detail. We check our evaluations regularly to achieve continuous improvements in the quality of the data and in the calculation factors (consistency, accuracy). We do this because this is the only way to obtain an accurate analysis.
Scope 1 includes direct emissions, for example emissions arising from the use of fossil energy sources. At Lohmann, these emissions arise primarily through the use of natural gas and gasoline or diesel in company vehicles. In addition, there are emissions arising from small quantities of process gases.
Scope 2 includes purchased or acquired energy. At Lohmann, this only applies to electricity, which we generate for our foundry in a climate-neutral manner using our own hydroelectric power plant and our own photovoltaic system. For this reason, there are no Scope 2 emissions at Lohmann. The footprint for the construction of the plants is taken into account in Scope 3.
Scope 3 includes a large number of emissions from upstream and downstream processes. The upstream processes are especially important and were taken into account accordingly. The goods and services purchased were fully documented and evaluated. Capital goods such as investments were valued and depreciated according to the imputed depreciation with the corresponding CO2 footprint. Fuels and purchased or acquired energy, insofar as these do not fall under Scope 1, have also been taken into account. Employee commuting to the workplace was documented down to the kilometer and evaluated. Upstream transportation, for example of raw materials and supplies, was also documented and evaluated wherever such transport was the responsibility of Lohmann. The waste produced was also documented and evaluated. Furthermore, business travel by air or car, including business travel by our independent sales representatives, was documented and evaluated. Rental and leasing rates were also documented and evaluated. In the downstream processes included in Scope 3, all items required for the transport and distribution of our products to our customers’ factory gates, whenever the transport was initiated by Lohmann, were documented.
