Businesses have historically had a negative impact on the environment by contributing to pollution, the increase of greenhouse emissions, neglection of responsible waste disposal, and deforestation among other things. In this paper we present an exploratory case study of an IT consultancy firm and their perspective and work with sustainable development. As a consultancy firm, the company does not provideservices directly to end users, but rather help clients in their business efforts. The aim with this project has been to explore how sustainability concerns can be integrated into the work processes of an IT consultancy firm, exploring both opportunities and challenges.
