Impact Assessment

Environmental Impact Assessment (EIA) is a tool to identify the environmental and social impacts of a project before decisions are made.

EIA helps predict environmental impacts at an early stage in project planning and design, while also contributing in finding ways to reduce adverse impacts. Also, EIA can help adjust projects to suit the local environment as well as present predictions and options to decision-makers and the public.

EIA experience

Ramboll has many years of experience carrying out EIAs for onshore and offshore oil and gas supply facilities, road constructions, airports, ports, bridges, industries, and so on. We facilitate EIAs for various international, regional and local clients (international financial institutions, private companies and national authorities and directorates).

EIAs must often comply with legislation. They provide information on the following key topics:

  • Detailed project description, noting the sources and impacts of environmental disturbances.
  • Complete list of alternatives, including those rejected and detailed examination of those under serious consideration. 
  • Description of the project environment, including fauna, flora, air, soil, water, humans, landscape or cultural heritage.
  • Detailed estimation of nature and scope of environmental impacts, including temporary and permanent as well as local and regional.
  • Proposal of mitigation measures, based on expected impacts.
  • Non-technical summary of the project and its likely impacts, written for a broad range of stakeholders including the general public.
  • List of potential problem areas, or unknown factors, with suggestion for research to fill knowledge gaps.

Managing authorities and the authorisation process

In addition to carrying out the technical aspects of EIAs, we also offer to be responsible for maintaining the necessary contact with authorities and managing the authorisation process throughout the EIA procedure.

Citizen involvement

Ramboll is very experienced in preparing and participating in public information meetings to involve local citizens and other interested parties, such as NGOs. We believe that complaints and suggestions from the public can strengthen projects, since our experience has taught us that the best projects involve all interested parties.

Interdisciplinary approach

Ramboll combines an interdisciplinary approach with a high level of professional expertise and we always work closely with our customers – from problem clarification to project completion – keeping costs to a minimum. We have extensive EIA experience from various sectors, often in projects that are both complex and large.

Each of Ramboll’s national EIA teams is highly experienced in working in partnership with experts on road construction, private and industrial construction, traffic, risk management and geophysics. These partners may be from within Ramboll, from different companies, or perhaps from developers’ own specialist groups.

Ramboll’s long experience working on international projects has eliminated the borders between national EIA teams. We often work across national boundaries, and always comply with the Espoo Convention on EIA.

To better understand the scope of environmental impacts and present alternatives to the public, Ramboll produces professional simulations, in 2D or 3D visualisations.
