ISO 14001 approach?

My first advice is about making a Gap Analysis to have an idea about what needs to be done. Then, you can develop your implementation plan.

Be sure to invest your time in determining and evaluating environmental aspects and impacts, they are very important for the foundation of your environmental management system (EMS). Consider also this article with a checklist for implementing an EMS - List of ISO 14001 implementation steps - https://advisera.com/14001academy/blog/2019/08/27/key-iso-14001-benefits-to-customers/nowledgebase/list-of-iso-14001-implementation-steps/
