The Upper Lusatian climate protection network

Upper Lusatia in Saxony was the first region in Germany to set up an energy efficiency and climate protection network under a joint national initiative between government and the business community.

ATN joins climate neutrality network

Climate protection, energy efficiency and the responsible use of resources are topics that must not only be discussed and addressed on the global political stage, but whose implementation already begins in private households as well as directly in companies. ATN also feels responsible for doing everything in its power to offer future generations an intact environment that is worth living in. This task is difficult to realize alone and can only be accomplished in community. For this reason, ATN is grateful and proud of the cooperation and partner network that has been built up in over 20 years of company history.

This network also includes the Zittau/Görlitz University of Applied Sciences, with which ATN already cooperates in several areas, such as regional development, topics related to educational content or the promotion of scholarships. This has recently been supplemented by cooperation in the "Energy Efficiency and Climate Protection Network Upper Lusatia 3". In addition to the Zittau/Görlitz University of Applied Sciences, the network sponsors are the Dresden Chamber of Commerce and Industry  and the Saxon Energy Agency SAENA. This makes ATN one of over 2200 businesses showing their commitment to climate policy by joining the initiative across Germany.

Reducing greenhouse gases and saving energy

The network is part of a joint initiative between the federal government and the business community. As part of the National Action Plan on Energy Efficiency (NAPE 2.0), by 2030 the network aims to save up to 6 million tons of greenhouse gas emissions and up to 11 terawatt hours of final energy (energy consumed by end users).

Structured cross-company and cross-sector discussions in the alliance are geared towards improving energy efficiency in companies so as to meet these targets. By sharing experiences, best practice examples and specialist advice, members can develop their expertise in this area.

ATN takes energy efficiency seriously at its head office in Oppach

Quite apart from its involvement in the network, ATN is a long-standing proponent of energy efficiency. Since 2008, most of the company’s power and hot water requirements have been supplied by combined heat and power (CHP) plants that were built in conjunction with ATN’s premises in Oppach. And when it was time for the first site expansion, we added a large solar installation to the roof. The forthcoming third construction phase will boost these capabilities yet again, totalling 200 kW of electrical power from CHP and 430 kWp from solar panels.

Zu den langfristigen Unternehmenszielen der ATN gehören ein verantwortungsbewusster Umgang mit Umwelt und Ressourcen sowie die Investition in moderne Technologien zum Schutz des Klimas. Damit möchten wir für unsere eigenen Mitarbeiter, deren Familien und die Region den „Wirtschafts- und Lebensraum Oberlausitz“ bewahren und stärken.

ATN's long-term corporate goals include a responsible approach to the environment and resources as well as investing in modern technologies to protect the climate. In this way, we want to preserve and strengthen the "Upper Lusatia economic and living space" for our own employees, their families and the region.
