Public sector > Planning and environment Tier 1

POSSER SPIETH WOLFERS & PARTNERS has established itself as one of Germany's top firms for environmental and planning law matters, which is not least due to its 'highest level of expertise' in this field. The team has taken on a formative role in the context of the currently most important environmental issues, such as advising on matters related to the national coal phase-out, assisting with large hydrogen projects and filing a successful constitutional complaint that entails central implications for the further development of offshore wind regulation. The team represents clients in contentious proceedings before German and European courts and assists affected companies with climate proceedings, among other matters. Large-scale planning matters represent another part of the practice: here, Herbert Posser contributes particular expertise in structuring complex approval proceedings. Wolf Friedrich Spieth advises and represents clients 'professionally and personally with extensive experience' and Benedikt Wolfers has expertise in potential liability crises as well as in advising on policy- and government-oriented matters. Niclas Hellermann is highly regarded and Katja Schramm made partner in January 2021.


‘Highest professional competence, extremely innovative and without the bow wave of big law firms. A really successful case of boutique start-up. And the partners work on the mandates themselves, no delegation down to the Hiwi level.’

‘Outstanding in every respect: Wolf Spieth – professionally and personally with extensive experience, in an advisory capacity and in the process. Think ahead and communicate clearly, pragmatically and undogmatically, thinking outside the box!’

Litigation: we have more than 20 years’ experience of complex proceedings before administrative and constitutional courts, European courts, civil and international courts of arbitration as well as before regulatory and environmental agencies.

Groundbreaking projects for the future: we evaluate, structure and safeguard new, groundbreaking projects with clients. This includes political-legal communication and advice on potential new regulatory mechanisms and legislation.

Political know-how: we are well aware of political parameters for the implementation of projects that are often controversial. We have firm contacts that go back decades and a major reputation in the political sphere. We are able to lobby on our clients behalf, and we are used to distilling complex legal issues to the key points and coordinating with clients or their advisors legally and efficiently.

Areas of expertise

We know the sectors and cases in which regulation and environmental law become relevant:

Energy and climate regulation
We have been at the forefront of pivotal energy law projects and have helped to shape Germany’s energy transition from nuclear exit through to coal exit to offshore wind energy. We know all the issues, our team brings together outstanding experience and competence in the field of energy and climate regulation.

Automotive and new mobility
The regulatory challenges in the automotive sector are international and carry high liability risks. We know the technical foundations as well as all the hurdles and phases where regulatory advice is needed.

Industry and environment
We have got vast expertise in obtaining licenses to operate for major industrial projects and we give advice on the entire range of environmental law relating to industrial production, including transactions and dealing with NGOs and the public.

We advise on transactions and structural questions for public banks and insurance companies as well as on the regulation of financial markets, European banking supervision and bank liquidation.

Infrastructure and transport
We help clients with the making, securing and defending of their infrastructure project – from regional planning, line management and urban land use planning to complex approval procedures and planning law. We also provide innovative ideas for efficient regulations for the safeguarding of major infrastructure projects, for the inclusion of stakeholders and the public and for the defence of projects before courts.

Mining, water and raw materials
With our decades of expertise in mining law, mineral extraction and water management, we have shaped the legal landscape for companies and the state.
