A philosophical view to this would be, would you have a larger impact by making ‘green-only’ projects, or by trying to make general projects more green? I’m just a student with little IRL work experience, but it feels like those contacting a consultant who’s ‘green’ have already made their minds that they want it that way.
Of course ‘green’ isn’t something a company wants to pick up just for the fun of it. There’s a ton of selling points, though - from better brand image to actually being able to use cheaper materials, even using something that the neighbouring company produces as a by-product. Green is a good selling point - as long as you can turn it into a positive cash figure!
