Welcome to TNL!

Individually tailored spatial and environmental planning services for municipalities, companies, and public authorities. Concept development, planning, and implementation — all from a single, interdisciplinary source.

We at TNL are a nationwide network of environmental planning offices in Germany. By combining our expertise, skills, and administrative structures, we form a strong partner for customized environmental planning and permitting consultancy.

Our environmental planning work covers a wide range of projects in the energy sector — including grid infrastructure, wind power, and solar farms — as well as transport infrastructure, species and nature conservation, and spatial planning (urban land-use planning, land-use plans, regional planning procedures). To achieve this, we rely on a diverse team of specialists in environmental sciences, environmental management, biology, geosciences, wildlife ecology, as well as forestry and agricultural sciences.
