According to the study "Light as the key to global sustainability", the photonics industry should achieve at least 11 percent of the internationally agreed CO2 savings by 2030. As determined in the study, it is already thanks to photonics that over 1.1 billion tons less CO2 has entered the atmosphere. By the year 2030 it should be over 3 billion tons. With reduced power consumption, CO2 emissions or the use of fertilizers, material reduction, new recycling processes and new technologies for environmental protection, photonics offers answers to the most pressing challenges of our time - climate protection, reducing greenhouse gas emissions and achieving the goals of the Paris Climate Protection Agreement. 2030 marks a milestone on the way to climate neutrality. According to the Paris climate protection agreement, this is to be achieved by 2050 by limiting global warming to 1.5 degrees.

The study by the industry association SPECTARIS, Messe München in cooperation with Fraunhofer ILT and the Fraunhofer Group Light & Surfaces describes exemplary technical applications and innovations with light as well as the corresponding ecological contribution. Accordingly, the current contribution to CO2 savings should almost triple by 2030.

The photonics industry can thus contribute at least eleven percent to the goal of limiting the temperature increase to 1.5 degrees.
