ESS Engineering Software Steyr GmbH has been a pioneer in the automotive industry since 2015, specializing in sustainable software solutions. Our mission is to revolutionize automotive manufacturing by optimizing energy and material consumption while minimizing environmental impact. With cutting-edge simulations and compliance with global sustainability standards, we are proud to lead the way toward a greener future.
Our software is designed to deliver impactful sustainability results across the automotive value chain. By reducing CO2 emissions, energy consumption, and material waste, ESS actively contributes to global sustainability efforts, including SDGs 9, 12, and 13.

We drive innovation in the automotive industry by delivering innovative software that reduces energy use, minimizes material waste, and enhances production efficiency. Our advanced technologies, like GPU-driven simulations, empower the automotive industry to adopt eco-friendly practices while maintaining competitiveness.

ESS enables responsible manufacturing by reducing material use (4 kg per prototype) and energy consumption (100 kWh per car body). Our solutions promote waste reduction and resource efficiency while fostering sustainability across the supply chain through training and compliance programs.

ESS helps manufacturers cut CO2 emissions by 17,000 tons annually for 300,000 vehicles—equivalent to 19 global flights of an airliner. Our energy-efficient technologies and material optimization actively combat climate change and advance a low-carbon future.
