Photonics Deliver 11 % of Global CO2 Savings

A new study shows the enormous importance of technical light applications in meeting the targets of the Paris Agreement: 1.1 billion tons less carbon dioxide already and three billion tons in 2030. Photonics makes a significant contribution towards 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, eleven percent of the COsavings achieved will be due directly or indirectly to applications in the field of photonics. These were the findings in a new 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 on June 24 at the press conference in Munich for the opening of the trade fair Laser World of Photonics 2019.

“Climate control and environmental protection are the greatest challenges humankind is facing. 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, technologies line photovoltaics, energy-efficient lighting, and optical communication are part of our everyday lives and reduce climate-damaging emissions considerably. ”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 will be able to claim to contribute at least eleven percent towards achieving the target of limiting temperature increases to 1.5 degrees, or 2 percent of the slightly less ambitious 2-degree target of the Paris Agreement respectively.

Reinhart Poprawe, head of the Fraunhofer Institute for Laser Technology ILT and professor at RWTH Aachen University, emphasizes: “Our society is currently facing the challenges of mega trends such as mobility, energy, communication, climate control, security, and health. Effective solutions are needed fast. Photonics offers solution approaches for the challenges resulting from these mega trends. In many cases, this benefits the environment.” Poprawe continues: “Photonics-based solutions have already been presented three times with Europe’s richest environmental award, the German Environmental Award.” And there are now 32 Nobel Prize winners in the field of photonics.

Reinhard Pfeiffer, Deputy CEO of Messe München, adds: “Our Laser World of Photonics fair 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.”

Spectaris CEO Mayer is certain: “The future of photonics has only just begun. Our study should also be seen as a plea to support the high importance of photonics with committed research, research subsidies, and innovation-friendly general conditions.” (Source: Spectaris)
