Legal watch: a tool to help companies achieve regulatory compliance.

Companies must comply with environmental, energy, and safety laws to avoid liability. However, the law is constantly evolving, and the mass of information is sometimes difficult to process within a company.
Therefore, under the responsibility of Marie-Pierre Maître, Atmos Avocats offers regulatory reference systems and strategic and regulatory legal monitoring designed for its clients.
The proposed legal watch monitors, analyses, and explains legal, regulatory and jurisprudential developments in the environment, energy and safety. It is intended to be easily accessible, requiring clear and synthetic comments.

The assets of Atmos Avocats in terms of monitoring

  • Fifteen years of experience
  • Its commitment to exhaustiveness in terms of published texts
  • Customization of the products to the needs of the companies
  • A monthly oral presentation to ensure an excellent legal understanding of the new texts and the dissemination of the information internally. This oral presentation seeks to ensure that the information is correctly disseminated to the beneficiary company when determining which sites and products are affected and identifying the problems of application raised by the new texts.

Legal support on the Hotline 

The Hotline complements the legal monitoring service. It can be used to clarify the application of a text identified in the monitoring; a recent legal question that does not require in-depth research by a lawyer in environmental law; initial theoretical advice, or documentary research.

Objective achieved 

The legal analysis of the texts is reviewed at each stage of the procedure for drafting the standard, and the comments in the legal watch highlight the changes made.

By being aware of this monitoring, the company can prepare action plans for compliance, particularly regarding its subsidiaries.

It can also anticipate the consequences of regulatory changes at the strategic level, especially in its contractual operations.

Finally, this monitoring enables Atmos Avocats to carry out lobbying actions seeking to improve the standard currently being developed.
