How to start career in ESG ?

Joined big 4 recently, after MBA, thought would land-up in strategy roles but placed in functional ERP role, Considering fresher with 0 tool knowledge in SAP, post mba along with 3.5 yrs of exp in amazon this is a fresh start for me. So thinking to move towards ESG as this motivates me a lot to work, how is this space, to move lateral in same org need 1.5 yrs mandarory exp in same firm, Want to apply with same package outside but i know would get less benefits with what i have now, but atleast would start working on ESG field and grow from here.

How is this industry in India, would like to know more thoughts
