EIA and environmental permitting procedures
EIA brings more than just a regulatory obligation to your project
The Environmental Impact Assessment (EIA) procedure is not merely a legally required step; at its best, it serves as a strategic tool for project development. A well-planned and properly executed EIA supports decision-making at an early stage, identifies risks in time, and helps optimize project implementation alternatives.
A high-quality EIA process improves a project’s:
- economic viability
- feasibility
- stakeholder acceptance
- schedule management
We have strong experience in delivering EIA procedures for large, complex, and schedule-critical projects across various sectors.
EIA services – comprehensive expertise
We provide full EIA services throughout all project phases, delivering demanding EIA procedures for, for example, the following sectors:
- forest industry
- energy industry, including renewable energy
- battery industry
- waste management and circular economy
- infrastructure and transport investments
- port operations
- chemical industry
We take care of all assessments and studies related to the EIA process:
- Noise studies and modelling (CadnaA)
- Air quality studies and modelling (AERMOD)
- Biodiversity surveys and Natura assessments
- Social Impact Assessment (SIA), including resident surveys and workshops
- Landscape and cultural environment studies, including 3D modelling and visibility analyses
In addition, we efficiently manage cooperation with authorities and stakeholders throughout the EIA process, which helps accelerate the process and reduce risks.
Environmental permits – a smooth process following the EIA
A successful EIA provides a strong foundation for the environmental permitting process. A professionally prepared permit application speeds up processing and improves the likelihood of obtaining approval.
We offer comprehensive environmental permitting services:
- from assessing permit requirements
- to preparing the application
- all the way to a legally binding permit decision
We specialize particularly in environmental permits for the process and energy industries, while also serving broadly, for example, circular economy and infrastructure projects.
Expert services for environmental permits and EIA
We provide all necessary supporting studies for both EIA and environmental permitting processes:
- BAT (Best Available Techniques) assessments
- Monitoring plans
- Baseline studies of soil and groundwater
- Environmental risk analyses and preparedness plans
- Water permit applications and emission permit applications
We can take full responsibility for managing the entire permitting process and EIA procedure, including authority liaison, responses, and appeals.
EIA and environmental permits – ensuring smooth project progress
By combining strong EIA expertise with in-depth knowledge of permitting processes, we ensure that your project proceeds efficiently, in a controlled manner and sustainably.
