Thanks to fiber optics: M-net becomes the first climate-neutral telecommunications provider

M-Cube: M-net Headquarter in München

Fiber optic right into the houses or apartments saves massive amounts of energy compared to DSL and cable internet. TÜV Rheinland has now confirmed M-net’s climate neutrality for the first half of 2021.

Bavaria’s leading fiber optic provider M-net is the first climate-neutral telecommunications provider in Germany. The company announced this on the occasion of its 25th anniversary this week. As part of an ambitious climate strategy, the company has already saved around 90 percent of avoidable greenhouse gas emissions since 2019. The Munich-based fiber optic provider has been working on reducing its CO2– Consistently reduce footprint. The company has been pursuing its own climate strategy since 2020, which was developed and implemented together with external experts from Bosch Climate Solutions. On the analysis of the CO2-Imprint in the base year 2019 was followed by the conception and implementation of measures to reduce greenhouse gas emissions. M-net is based on the 4-lever concept from Bosch Climate Solutions, which is based on four differently weighted approaches to achieve high-quality climate neutrality. These include increasing energy efficiency, expanding renewable energies, purchasing green electricity and offsetting unavoidable emissions. For the first half of 2021, TÜV Rheinland, as an external testing company, was able to determine the climate neutrality of M-net.

Last but not least, an important basis for the company’s strong carbon footprint is the high-performance fiber optic infrastructure, which M-net is continuously expanding together with the municipal utilities and bringing it closer and closer to the individual apartments and offices of the customers. In contrast to copper-based technologies, transmission via fiber optics requires significantly less energy and, at the same time, higher performance features.

Green electricity and fiber optics help the climate

M-net has carried out a number of measures in recent years to make the company completely climate-neutral. This included, for example, the use of energy-efficient light sources, intelligent lighting control and temperature optimization in the data centers. Since summer 2021, individual fiber optic distribution cabinets (FTTC containers) have been equipped with photovoltaic systems for their own energy supply. In addition, M-net operates all of the company’s own locations where there is a choice of electricity purchase, as well as the data centers with certified green electricity.

The total remaining CO2-Emissions according to Scope 1 and 2 amounted to a total of 387 tons in the first half of 2021 – less than an aircraft emits on a single one-way flight from Munich to New York. M-net offsets these emissions with certificates for an international climate protection project. The telecommunications provider is currently promoting the “Clean drinking water Diana Madagascar” campaign. In addition, M-net is also active locally at home and is supporting a climate project for reforestation in a forest near Poing near Munich this year. From 2022 the vehicle fleet will be completely converted to electric vehicles. Compared to other transmission paths, fiber optics are more powerful and sustainable, as they do not need to be converted into electrical signals. According to a study by the Federal Environment Agency, the type of data transmission used for video streaming is decisive for the carbon footprint. Video transmission via fiber optics causes half as many greenhouse gas emissions as VDSL and is almost 50 times more efficient than UMTS. “With a continuous fiber optic supply, i.e. only FTTH, we could achieve around 330,000 tonnes of CO in a city like Munich compared to VDSL transmission over copper lines2 save each year “, says Dr. Hermann Rodler, Technical Director at M-net.
