In efforts to further reduce the environmental impact of transportation for purchasing and sales, Werner & Mertz has thoroughly examined its finished goods logistics since 2009/2010. In the process we identified sustainable improvement potential along the entire supply chain.
The focus is on the savings potential of carbon dioxide (CO2) and other greenhouse gases. CO2 is primarily responsible for the greenhouse effect and global warming. The analysis of Purchasing, Production and Sales identified reduction steps and ranked them according to their effectiveness. Progress made with sustainability measures is regularly reported and new steps are taken in pursuit of continuous improvement.
Finished Goods Logistics
Finished goods logistics covers everything from receipt of goods in the warehouse to delivery to the customer, including in-house logistics and external logistics services. It takes into account consumables and packaging materials and required energy and heating. Distinctions are made according to distance, truck class, EURO class, capacity utilization, etc. Warehousing operations at Werner & Mertz are also closely examined.
The first examination in 2010 showed that about one-quarter of CO2 emissions was attributed to the company's internal processes on site and more than one-quarter to intercompany transport, specifically to transport and processes between the main warehouse and regional warehouses. The greatest amount of greenhouse gas was emitted by sales transport as most finished goods transport is done by truck. Because most customers have reduced their own stockholdings, Werner & Mertz has to deliver small quantities on short order more often. To guarantee a flexible response time and ensure deliverability, we cannot turn to rail transport even though it is environmentally friendly and therefore desirable.
In the selection of transport services and trucking transport, we consider the amount of energy consumed and CO2 emissions along with the modernity of the vehicular fleet. A truck in EURO Class 5, for example, emits 85 percent less nitrogen oxide than a truck in EURO Class 0. The EURO Class 5 vehicle has even better values in fine dust and non-methane hydrocarbons, both of which are hazardous to human health. Consequently, Werner & Mertz favors use of a modern truck fleet operated by drivers who have been trained in fuel conservation methods.
