Acting Responsibly

LEM is committed to sustainable development and has a long tradition of acting responsibly. While carrying out fundamental structural changes in the last few years we ensured they had no impact on LEM’s economic, environmental or social aspects of LEM’s activities.

Economic performance

Economic performance comes first. The company targets growth and high profitability. All our divisions operate in attractive markets. Thanks to their leading positions and increasing efficiency, they all have high-value creation potential.

Responsibility towards our people

LEM is a responsible and attractive employer, giving employees the opportunity for personal growth in a challenging and rewarding environment. Cooperation between social partners is part of our corporate tradition and played a pivotal role during our corporate restructuring process.

Environmental protection

LEM has two main ecological areas of focus:

• Internally
LEM seeks to maintain or reduce energy and water consumption as well as waste volume levels and per value added at every single location. In addition, LEM has strict policies in place to prevent environmental accidents.

• Externally
Our divisions offer products and services that are eco-efficient and we help our customers to combine lower costs with reduced environmental impact.
