About us

adelphi consult is a leading independent consultancy specialising in climate, environment and development. Together with adelphi research and adelphi global, we combine scientific analysis, evidence-based advisory services and international cooperation. As a strategic policy and management consultancy, we support the just, transformative transition towards a sustainable, future-proof society. 

Our experts work locally and globally on the key challenges of political, economic and social change. We are agents of the future within a global network of strategists, practitioners, forward thinkers and critical analysts. Through transdisciplinary research, evidence-based consulting and stakeholder dialogues, we shape policy agendas, facilitate political communication, inform policy processes, and support decision-makers.

• We are strategists with global networks, consultants committed to making the world a better place, courageous visionaries.
• We think holistically and are solution-oriented.
• We are passionate about shaping the socio-ecological transformation.
• Our goal is impact.
• We conserve resources and are climate-friendly in our actions.
• For us, ideas and initiative count over hierarchy.
• We get things moving in a collaborative and creative way – from ideas to implementation.
• Our quality standards are rooted in the professional and social proficiency of our advisors.
• Our work enhances decision-maker competence.

Since 2001, we have successfully completed more than 1,820 projects worldwide for numerous international clients and partner organisations in the fields of energy, climate, resources, finance, diplomacy and business.

Sustainability is the basis of our internal and external conduct. We are committed to a future fit for grandchildren, reduce our CO2 emissions where we can and offset those that are currently unavoidable. We purchase 100 per cent green electricity, consistently rely on environmentally friendly and socially responsible procurement and use ethical financial services. Through our project work, we contribute to increasing positive environmental performance. The responsibilities and processes of our corporate environmental protection are certified according to the EMAS seal of approval, the highest European certification for a systematic environmental management system.

Since 2022, the Munich-based investment company Deutsche Private Equity (DPE) has invested in adelphi consult as a shareholder. As a financial investor, DPE actively invests in medium-sized companies in Germany, Austria and Switzerland. With professional expertise, experience, trust and respect, DPE accompanies adelphi's growth path as a partner.

As of 1 January 2026, we have updated our structure. The non-profit entities adelphi research and adelphi global are now independent but closely connected legal entities.

adelphi research/global (gGmbH) will focus on non-profit research projects and the transfer of scientific findings into practice. 

adelphi consult (GmbH) will continue to focus on strategic consulting and service projects in the public and private sectors. 

Each entity will be managed independently, enabling a clearer focus on its respective core areas.

adelphi consult (GmbH) konzentriert sich auf strategische Beratung und Dienstleistungsprojekte im öffentlichen und privaten Bereich.

Beide Einheiten werden künftig eigenständig geführt und können sich so noch gezielter auf ihre jeweiligen Kernbereiche konzentrieren.
