Hi Heva, when we look at defining sustainability for a strategic objective, we really need to look at it in two ways. First, there is the overall sustainability of the company, meaning, can they survive long-term, grow and perform. This can happen by being profitable, having good employee relations, and managing your P & L correctly to ensure your bottom line remains healthy. Then, there is sustainability that is green in nature. Lower carbon emission, energy efficient buildings, etc. So the word has two meanings, and it is important to understand which one you are working with, then take it from there. I hope this helps. If I can help more please reach out to me.
