Rather than making generalized statements about how the project will affect you, your community, or the surrounding environment, your comments will be more effective if they specify provisions of domestic laws and regulations that the EIA or proposed project violate.


As our Portuguese constitution guarantees access to clean water and guarantees a right to live in a healthy environment, it is recommended that these legal rights be highlighted in your written comments if they are likely to be affected by any proposed oil & gas exploration project (onshore and offshore).



Submitting written comments is important for demonstrating, in later stages, that you participated in the EIA review.

If you decide to appeal the approval of an EIA for a particular exploration project, your case will be stronger if your written comments cover all the issues you may later want to raise in court.



List of Environmental Attributes that you need to consider when writing your comment

This list, gives you some idea of impact areas when you are writting your submission. Responses to the Identification of Environmental Impacts can be framed by answering the question:

Does the undertaking or related activities (during construction, operation or maintenance) have the potential to affect or be affected by any of the following environmental attributes? If so, then describe the impact and the proposed mitigation.

Note: the following is a guide only and is not intended to be an exhaustive or a prescriptive list.
