Climate Action

SDG 13: All for one

Since 1990, global CO2 emissions have increased by almost 50 percent. To reverse this trend and limit global warming to a maximum of two degrees Celsius over pre-industrial times, technical innovation is just as decisive as fundamental behavioral change. Bosch supports the targets of the Paris climate agreement in a number of ways, for instance by consistently improving the environmental performance of the company’s locations around the world.

The Bosch Group’s environmental management system is based on the following targets: to reduce CO2 emissions by 35 percent until 2020 relative to value added over the 2007 reference year, as well as to achieve a 6 percent reduction in volume of waste and water consumption between 2016 and 2018, also relative to value added. To achieve these targets, the company has introduced the ISO 14001 environmental management system at all 296 Bosch manufacturing sites, just like at the larger development locations. So far, 87 percent have received external certification. At many plants, energy officers cooperate with the CO2 coordinators of each division to develop emission reduction measures. Via the Bosch Connect internal communication platform, the environmental experts share ideas and ensure that successful approaches are implemented across the company. 

 

Reducing energy consumption with load management

In 2016, the Bosch plant in Nuremberg was one example of this. The production site successfully reduced expensive peak loads, thus saving 700,000 euros in energy costs in their first year. First, experts at the plant conducted a systematic analysis of energy consumption using 360 electricity meters that were read several times each day. The experts used the results to come up with a range of measures: they replaced energy-intensive components and installed solar panels on the plant roof. In addition to this, the site rescheduled energy-intensive processes to night and weekend shifts with the aim of achieving more constant levels of energy utilization. Since then, cooling systems have been used at times when energy use is lower, while a newly installed cooling reservoir ensures that the required cooling process is available at all times. In 2016, the plant received the automotive supplier industry’s “Partslife Umweltpreis” (Partslife Environmental Prize) for its progressive energy management system. 

At other locations, too, analyses of energy use help achieve the energy and CO2 reduction targets that Bosch has set itself. At the Bosch plant in Nonantola (Italy), one of the most important projects implemented in 2016 regards the heat recovery wasted from the cooling system of the compressors in production for heating purposes. This had a positive effect on gas and electricity consumption, and has led to a CO2 reduction of 50 tons per year. At the Bosch plant in Mississauga, Canada, heating costs were reduced by 12 percent after air barriers were installed at the site gates. 

Key environmental figures

At the Nanjing and Chuzhou production sites in China, lighting was identified as a major driver of costs. Within a year, the plants replaced thousands of lights with energy-efficient LED lighting. As a result, they saved about 2.6 million kilowatt hours of power and cut their electricity bills in half.

A concept for less waste

With the aim of seizing all opportunities to reduce waste, the Bosch plant in Naganathapura, India, developed the “3R concept,” which is based on the idea that waste can be systematically reduced, reused, or recycled. Take oil filters, for instance: following a cost-benefit analysis, the location purchased an oil centrifuge, which is necessary to clean oil filters. As a result, the volume of hazardous waste at the location was decreased by 25 percent over the previous year. Within the first year, the savings generated with regard to waste disposal paid for the new equipment.
