Environmental Permitting

The management of environmental issues is now a strategic element for companies that aim to operate in full compliance with environmental regulations and to integrate sustainability into their corporate strategic vision.

In this context, NIER supports companies with comprehensive, hands-on assistance in Environmental Permitting, guiding them through every stage of the authorization process: from the preliminary analysis of requirements and regulatory constraints, to the preparation of technical documentation, and through to discussions with and submission of applications to the competent authorities. This practical support is designed to simplify procedures, ensure clear timelines, and guarantee regulatory compliance.

Specifically, we assist our clients in obtaining, amending, and renewing environmental permits required by law, such as Integrated Environmental Authorization (AIA), Single Environmental Authorization (AUA), sector-specific permits, permits for waste management facilities, and authorizations for energy production plants.

We carry out analyses and studies for Environmental Impact Assessment (EIA) of new projects, Strategic Environmental Assessment (SEA) for planning instruments (VAS/ValSAT), and Appropriate Assessment (AA) for projects and plans affecting Natura 2000 Network areas (VINCA).

We apply state-of-the-art methodologies, models, and tools for predictive analysis, environmental monitoring, and mitigation of impacts related to noise, atmospheric pollutant emissions, water and soil contamination, as well as waste and hazardous substances management.

We prepare Management Plans for Protected Natural Areas to safeguard the environment and natural heritage and preserve biodiversity. We design and implement environmental and ecological monitoring activities.

We support companies subject to the European Union Emissions Trading System (EU ETS) in meeting their compliance obligations.
