Sustainability is a key theme at this year's Laser World of Photonics in Munich, where a recent study on Photonics and Sustainability is being highlighted. The study, "Light as the key to global sustainability", shows the enormous importance of technical light applications in meeting the targets of the Paris Agreement.
At Laser World of Photonics, there are numerous examples of how photonics makes a significant contribution toward reducing greenhouse gas emissions and reaching the targets of the Paris Agreement: through reduced power consumption, CO2 emissions, and use of fertilizer, by saving material and as a result of new recycling processes and technologies for environmental protection.
2030 is an intermediate stop on the road to carbon neutrality that is to be achieved by 2050 according to the Climate Change Agreement. The goal of the Paris Agreement is to limit global warming to 1.5 degrees. In 2030, 11% of the CO2 savings achieved will be due directly or indirectly to applications in the field of photonics. These were the findings in the study called “Licht als Schlüssel zur globalen Nachhaltigkeit” [Light as the key to global sustainability] from the German industry association SPECTARIS and Messe München in cooperation with Fraunhofer ILT and the Fraunhofer Group for Light & Surfaces. The study describes the ecological contribution of selected technical light applications and exposes the underlying innovations. It was presented today at the press conference in Munich for the opening of the world’s leading photonics trade fair Laser World of Photonics.
Climate control and environmental protection are the greatest challenges facing humankind. The technical achievements in photonics show that we already have important tools at hand,” says SPECTARIS CEO Jörg Mayer. “The things we have already achieved with lasers and light sensors were still regarded as science fiction just a few years ago. Today, these technologies are part of our everyday lives and reduce climate-damaging emissions considerably – technologies such as photovoltaics, energy-efficient lighting, and optical communication.”
It is expected that the current contribution to CO2 reduction will almost triple to approximately three billion tons by 2030. Consequently, in 2030, the photonics industry can claim to contribute at least eleven percent towards achieving the target of limiting temperature increases to 1.5 degrees, or, respectively, 22% of the slightly less ambitious 2-degree target of the Paris Agreement.
Professor Reinhart Poprawe, Head of the Fraunhofer Institute for Laser Technology ILT/RWTH Aachen University, emphasizes: “Our society is currently facing the challenges of megatrends such as mobility, energy, communication, climate control, security, and health. Fast, effective solutions are needed. Photonics offers solution approaches for the challenges resulting from these megatrends. In many cases, this benefits the environment.”
Poprawe continues: “Photonics-based solutions have already been presented with Europe’s richest environmental award, the German Environmental Award, three times.” And there are now 32 Nobel Prize winners in the field of photonics.
Dr. Reinhard Pfeiffer, Deputy CEO of Messe München, adds: “Our Laser World of Photonics, the world’s leading trade fair for optical technologies, showcases the incredible developments that have been made in the fields of lasers and photonics since 1960. We are presenting sustainability in the context of electric mobility – which would be inconceivable without laser technology – from battery production to lightweight construction and cockpit component manufacturing. Many of our exhibitors are companies that pioneered the links between photonics and sustainability.”
The technical use of light – photonics – enables countless applications in industrial and private areas, which would be inconceivable without this key technology. For example, the Internet is based on data that is transmitted by fiber optics and that circles the planet at the speed of light; displays, cameras, and sensors from smartphones are the interfaces to our human senses; and, thanks to optical systems, physicians can make accurate diagnoses and carry out treatments that are efficient and non-invasive. The German photonics industry is one of the most innovative areas in Germany and in the world and is also experiencing dynamic, long-term growth. Currently, in Germany more than 140,000 people work directly in the photonics industry, generating almost EUR 40 billion each year.
