Working together for GreEnergy

In an 18-month project in 2014 and 2015, we paved the way to a more sustainable, “green world” for a DAX-listed energy company with over 11,000 employees – a goal that is close to our hearts not only from a corporate social responsibility (CSR) perspective, but above all from a personal perspective.

Challenge: From coal-fired power plants to climate-neutral energy production

With the clear goal of becoming a company with “zero C02 emissions” in the near future, the operation of conventional coal-based power plants in Germany will be gradually reduced. We are actively helping our customers to increasingly switch to renewable energy generation and thereby usher in a new era of sustainable and climate-neutral energy production.


The energy company has decided to work with our team of experts for carve-ins and carve-outs on a long-term basis. Our expert know-how covers methods, technologies and in-depth industry expertise.


We are not only interested in economic figures and data-orientated facts, but also in what has fundamentally changed for our society and us humans in general. The reorganisation of energy generation and storage has noticeably reduced CO2 emissions. This improves the ecological footprint.

The interplay of legal regulations, economic efficiency and social responsibility is the basis for future-proof and sustainable action.

This is how we, as the C4 Group and as a company, counteract the man-made part of climate change. We actively reduce potential environmental damage caused by interventions in nature and promote the development of renewable energy generation through the right investments.
