Dear Sameer
your questions are discussed very often in this FORUM. Hi, is such an example, but you will a lot of more similar examples.
E.g.:
SAP PLM: Career outlook of EHS

Looking forward for your valuable suggestions please !!
Future Scope of SD for an abaper.
Therefore these are my hints:
Check first: SAP EHS Management for Beginners
Try to understand what SAP is doing (what means which solution exists and which solution is the right one to start with etc.).
To act a functional guy in SAP area you need basic understanding about SAP solutions.
1.) Shortly: there is no SAP certification in place for the SAP EHS solutions.
2.) Career: normally you ned first some basic SAP and SAP EHS training. The SAP training is available nearly worldwide. SAP EHS training is limited. E.g. there seems to be no good training option available in India (has been discussed as well in this FORUM).
Based on you "starter package" (know how) the "SAP EHS end user" option may be is the best. If you know about legal aspects/regulations etc. then by working on that in a company using SAP EHS solutions you will get closer to "technique" For work in EHS environment you need to have knowledge at least in the area (as called by SAP): product safety, dangerous goods management; as these are the "core" topics to cover in a company handling chemistry. On the top: if you have knowledge in the area of "Label Management" or "Waste" topics then you are in good starting position.
PLease check this FORUM. A lot of more threads can be found easily may be helping you to decide to go on.
