I was approached about a role at a company that is looking to optimise efficiency of oil refineries (the technology is potentially more broadly applicable to other industries, including agriculture, but the initial target is oil refineries).  I am able to argue two ways about the impact.

1. It is a negative impact role since it increases the profits obtained from oil which at worst encourages more rapid extraction.
2. The world is still reliant on oil, we cannot realistically stop extraction for several years, therefore optimising refining of that oil reduces waste and reduces the need for future extraction and is therefore a positive impact.

I think that (1) wins out here and that overall this is a negative impact role, but I'm relatively new to evaluating these things so I wanted to sanity check whether my intuition was correct.

P.S.  I realise that even if (2) is correct the impact is likely small in the grand scale of things, so not ideal for a future role, but I thought it was an interesting case in point for discussion.
