Welcome to ISG

Private Institute for Sustainability
and Impact Strategies, Training, and Finance

We support companies and institutions in aligning their strategies with EU sustainability requirements, transforming their financial operations, and promoting transparent, long-term growth.

Rethinking Sustainability –
holistic, measurable, effective.

Sustainability today is more than just a trend — it is a key driver of risk management, innovation, and the long-term success of companies and investments.

ISG supports companies and organizations not only in developing sustainability strategies but also in effectively integrating them across all areas of business — from supply chain and reporting to the financing of sustainable projects and business models.

We collaborate with leading developers of measurement methodologies and tools for standardized sustainability outcomes that align with EU regulations (CSRD, CSDDD, ESRS, VSME). In doing so, we help companies implement regulatory requirements efficiently and across departments.

In addition, we advise and support banks, companies, and educational institutions in designing training and learning programs on sustainability, impact, and sustainable finance – ensuring that knowledge and practice are seamlessly connected.

Whether you are seeking strategic advisory, impact development, or professional training, our experts from the fields of banking, research, project management, and corporate leadership bring over 25 years of experience to provide you with an integrated and future-oriented range of services.
