This paper investigates the current tools and frameworks for sustainability development assessments in industrial sectors and aims to find out the gaps between theory and practice toward sustainability assessments. An analysis of existing literature in the area of sustainability assessment tools has been complemented by interviews with experts in the area of sustainability and energy efficiency. Based on the body of knowledge and the practitioner feedback, time required and specificity are key challenges in sustainability development analysis. The paper opens the room for ideas concerning future research initiatives to overcome those drawbacks and challenges.
