Daimler 360 GRAD - FAKTEN zur Nachhaltigkeit 2008 Daimler Nachhaltigkeitsbericht 2008 / Environmental protection, innovation, and safety / Production / Production-related environmental strategy / Environmental data collection* Environmental data collection* Since resource consumption and emissions depend on the production volume, we calculated specific values for the individual divisions. To do so, we used the number of vehicles produced by a division in conjunction with the corresponding data from the production plants. Following the reorganization of the commercial vehicle units, the specific values of the Truck Group, Vans and Buses were calculated separately. To generate consistent time series, this distribution was also used, as far as possible, to calculate past values. The specific data generated by this means can only serve as a general guideline because it does not take into account differences in the development of vertical integration, product diversity, and the distinctive features of the production network, which partially extends across several divisions. * Content on this page is available exclusively on the Internet.
Daimler 360 GRAD - FAKTEN zur Nachhaltigkeit 2008 Daimler Nachhaltigkeitsbericht 2008 / Environmental protection, innovation, and safety / Production / Energy and climate protection Energy and climate protection Direct and indirect CO 2 emissions from production To reduce energy consumption at its plants, and thus CO 2 emissions, Daimler employs a dual approach that calls not only for ensuring the most environmentally sound energy supply processes possible for the production plants, but also efficient use of energy in production. The Group’s production locations are heated with natural gas, which is a low-carbon energy carrier, for example, and one plant uses shredded waste wood to achieve nearly CO 2 - free heating. Coke is used only where technologically necessary, which means for smelting cast iron. Many production plants are supplied with heat and power by highly efficient cogeneration plants operated either by Daimler or by regional power companies. For its new construction, expansion, and modernization projects, Daimler makes use of innovative low-CO 2 energy supply concepts and electricity generated from renewable sources. A new photovoltaic system at the Gaggenau plant, for instance, and existing photovoltaic facilities in Bad Cannstatt (Untertürkheim) and Sindelfingen (MTC Design building) regeneratively produced nearly 900 megawatt-hours of electricity in 2007. Daimler’s worldwide energy consumption totaled 10.2 million megawatt-hours in 2007, a decrease of 5.2 percent from the previous year. Along with generally mild weather, this reduction was mainly due to improvements in energy efficiency brought about by many energy-saving projects at our production plants. One outstanding example of our energy-saving achievements is offered by our Untertürkheim plant. Here, a facilitywide interdisciplinary project team set itself the goal of exploiting all possibilities for reducing energy consumption in areas as diverse as machine and facility planning, production infrastructure, and building systems, while also addressing the impact of employee behavior on energy use. The team approved and implemented a wide range of measures that proved very successful: � Raising the temperature of cooling lubricants cut the annual electricity consumption of refrigeration machinery by 15,000 megawatt-hours, without any detrimental effect on production quality. This same measure also significantly reduced cooling-water consumption. � Optimization of heat recovery equipment by means of improved controls, adjustments in line with requirements, and use of alternative heat sources led to annual heat energy savings of 11,000 megawatthours. Current plans call for further heat recovery savings totaling 18,000 megawatt-hours.
