Certain projects, plans and programs on the initiative of private or public individuals, must integrate environmental and health issues within their development procedure.

Carrying out an environmental assessment is then important, but it is a particularly sensitive step since the defects which could affect it can be the cause of significant delays or the source of illegalities which can lead to the cancellation of administrative decisions, authorizing or approving projects, plans and programs.

Valians intervenes to support public and private operators in the implementation of this assessment, right from its development to the related disputes (scope of application in regard to the project, updating, pre-litigation contestation of the submission for assessment, audit, action in courts).
