Environmental Policy

"We minimize our ecological footprint"

Although PSI as a software manufacturer only has a negligible impact on the environment, the group relies on sustainable and resource-saving technologies in its own business processes. PSI uses green IT equipment for its own infrastructure in order to save energy and resources. The cloud provider used internally and in customer projects by PSI has committed itself to reducing its greenhouse gas emissions by 65 % by 2025 and to zero by 2030.

In 2021, the user forum for the public transport business segment was held for the first time as a sustainable event in the Berlin Environment Forum. The environmental forum is the official Sustainable Event Partner of the city of Berlin.

Products and Services

For 50 years, PSI has been helping customers in the energy industry and in energy-intensive industries by providing software solutions to increase efficiency and use energy, raw materials and labor responsibly. PSI products thus have a relevant influence on the sustainability of business processes in the industries supported.

• PSI’s control systems for managing major electricity grids have been and still are continuously expanded with functions that enable the feed-in of renewable energy to be managed intelligently. Together with partners from the energy industry and academia, PSI is actively involved in developing the intelligent energy supply infrastructure of the future. This includes products for virtual power plants, smart microgrids and the integration of charging infrastructure for electric vehicles into the existing electricity grids. A self-learning network autopilot is available for large transmission and distribution networks, through which a higher proportion of renewable energy can be integrated into existing networks. Overall, up to 50 % more renewable energy can be transported through intelligently managed networks.

• PSI’s gas management systems optimize the transfer, distribution and storage of natural gas, green gas and hydrogen. They optimize the compressor stations required for grid operation and minimize technical losses. Leak detection and location systems help reduce losses when transporting gas and fuels over long distances and avoid environmental damage. By storing excess electricity from renewable sources using electrolysis and methanation, gas makes a positive contribution to the energy transition.

• When maintaining electrical networks and other critical infrastructures, business processes can be improved with PSI's own optimization software so that the same workload can be managed with up to 15 % less use of resources and fewer CO₂ emissions. By avoiding unnecessary load peaks, employee satisfaction improves at the same time.

• In the field of logistics and transport, PSI has in recent years developed new solutions for dynamic control of optimized logistics networks that help reduce transport costs and emissions by up to 10 %. Further functions include energy optimized driving in rail transport and a depot and charging management system to optimize the dispatch of zero-emission buses. In the first depot managed with PSI software, which was built specifically for electric buses, around 4,500 tons of CO₂ were saved in the first two years. In the meantime, PSI's decision-making optimization is helping more than 15 transport companies to reduce greenhouse gases and save energy.

• When optimizing the assembly sequences in the automotive industry using PSI sequence optimization, an average of 15 % of resources can be saved, which corresponds to an annual CO₂ avoidance of several thousand tons for a vehicle factory. In the steel and aluminum industry, PSI's AI algorithms optimize the use of energy and resources, and they also accompany the structural change to low-carbon steel production. The share of energy reuse in downstream process steps in an integrated steelworks could be increased from 5 % to 54 % through better planning, which resulted in energy savings of more than 20 %. Higher productivity and energy reuse are a big contribution to sustainability, as energy accounts for 20 to 30 % of production costs in the metal industry.

PSI is not involved in adult entertainment products, alcohol products, controversial weapons, firearms, fur and special leather production, gambling products or services, genetically modified organisms, military contracting, nuclear power generation, nuclear power related services, pesticides and tobacco products. Since PSI manufactures intangible goods, PSI's business also has no influence on protected or biodiversity-sensitive areas. Further information in the Annual Report 2021 (pages 46-48).
