Bosch to be carbon neutral worldwide by 2020

by Hans Diederichs

“We see climate action as our responsibility, and believe we have to act now,” says Dr. Volkmar Denner, chairman of the board of management of Robert Bosch GmbH. In a bid to swiftly achieve carbon neutrality, Bosch will buy more green electricity in the near term and compensate for unavoidable CO2 emissions with carbon offsets. In the years to 2030, the company will gradually increase the share of renewable energy in the power that it generates and buys, and will invest a billion euros to boost its locations’ energy efficiency.

Once Bosch achieves climate neutrality, it will no longer adversely affect carbon dioxide concentration in the atmosphere. The company is thus making an important contribution to the Paris climate agreement ratified in 2015, which calls for global warming to be kept well below two degrees Celsius above pre-industrial levels. “Everyone has to contribute to climate action,” Denner says.

Swift action to achieve early carbon neutrality

Industrial enterprises such as Bosch can make a significant contribution to the drive for global climate neutrality. According to the International Energy Agency, manufacturing accounts for around 32 percent of global carbon dioxide emissions. As it stands, Bosch emits around 3.3 million metric tons of carbon per year. The company has already reduced carbon emissions relative to its value creation by nearly 35 percent since 2007. “We are not starting from scratch. We have consistently exceeded our targets for the relative reduction of carbon emissions. Now the time has come for absolute targets. Let the final countdown begin,” Denner says.

Focusing on sustainable, renewable power supply

Starting in 2020, Bosch will compensate for any residual and unavoidable carbon emissions primarily by buying green power from legacy plants and taking part in carbon offset programs. The company is investing in environmental projects, certified to rigorous standards, aimed at supporting social and ecological development. Carbon offsets are to be gradually scaled back by 2030, and Bosch is stepping up investments in renewable energies to this end. It also intends to enlarge company-owned photovoltaic systems such as those in place at the Nashik and Bidadi locations in India. The company expects to achieve a tenfold increase in installed energy capacity with this move. Bosch will also sign long-term, exclusive supplier contracts with new wind and solar farms around the world, which can then operate profitably even without government subsidies.

A billion euros – and connected solutions – for greater energy efficiency

Enhanced energy efficiency is a powerful tool for achieving carbon neutrality. Bosch will invest a billion euros in the energy efficiency of its plants and buildings over the next ten years. “We want to reduce energy consumption and carbon dioxide emissions in absolute terms, and not just relative to value creation,” Denner says. By 2030, the company plans to save additional energy amounting to some 1.7 terawatt hours per year. This is more than one-fifth of its current annual consumption, and comparable to the amount of electricity consumed by private households in Cologne. Bosch has been vigorously pursuing environmental management practices for years. In 2018 alone, the company carried out some 500 energy-efficiency projects, reducing power consumption by close to 1.5 percent. Connected manufacturing has also become a key efficiency driver. Bosch has already deployed its proprietary energy platform, a part of the company’s portfolio of Industry 4.0 solutions, to more than 30 factories around the world. This platform is a cloud-based software solution that can track and control every single machine’s power consumption.


Climate action pays social and economic dividends

In the years up to 2030, the company will incur one billion euros in added costs by buying green electricity, engaging in carbon offset programs, and sourcing power from renewables. In that same period, Bosch will invest one billion euros to boost in-house energy efficiency. This increase in energy efficiency will save Bosch around one billion euros, thereby bringing the company’s expenditure on carbon neutrality down from around two billion to one billion euros by 2030. “Carbon neutrality is doable and, if pursued with the necessary determination, can be achieved quickly. Our investments benefit not only us at Bosch, but humankind in general as well,” Denner says.

A selection of exemplary Bosch projects:

The Feuerbach plant – energy efficient thanks to people and machinery

Feuerbach, Germany, is home to Bosch’s oldest location worldwide. Established in 1909, it has steadily and systematically modernized its facilities to contribute to the company’s overall energy efficiency. With training sessions in its “Energieerlebniswelt” (energy experience world), the local team focuses on energy monitoring and increasing awareness among the workforce. The plant has pursued heat recovery, room automation, machine power shut-off management, and shop renovation projects with great success. Its energy requirements are down more than 50 percent compared with 2007; its carbon emissions – relative to value creation – are down 47 percent.

Crunching data to conserve energy at Homburg

The Bosch location at Homburg, in the German state of Saarland, is edging ever closer to the vision of an energy efficient, self-learning plant. It has spared the world around 5,000 metric tons of carbon dioxide in the past two years and more than 23,000 tons since 2007. This approach pairs maximum transparency with technical innovation. An energy management platform developed by Bosch uses data from the machinery collected at some 10,000 measuring points. Associates can track, control, and optimize each individual machine’s power consumption. Technical solutions include ventilation of manufacturing shops on an as-required basis, utilization of waste heat from various machining processes, and smart consumption management for machinery.

Green roofs, photovoltaic systems, and carbon neutrality at Renningen

The Bosch location at Renningen has been carbon neutral since January 2019. Carbon offsets fully compensate for the carbon footprint of the natural gas burned by its heating system. The facility buys green electricity to cover its power needs. And the 460 photovoltaic modules installed on the roofs of buildings generate electricity for the campus’s own use. To help control temperatures inside the buildings, roofs on the research campus are covered in greenery; a 3,600 m3 underground cistern collects rainwater that seeps through the plant cover for use in the air-conditioning system’s cooling towers. The green rooftops also provide an insulating buffer against direct sunlight and excessive accumulation of heat on the roof. This combination reduces the amount of energy needed to air-condition buildings by 20 to 30 percent. The location also operates a water treatment plant that enables Bosch to conserve around 20,000 m³ of drinking water a year.
