This paper aims to provide a new approach to objectively assess hierarchies and priority setting in the relationship between environmental, social and economic sustainability within Sustainable Development. After a literature review, several widely used conceptual figures (diagrams) describing this relationship were assessed using SWOT analyses in order to identify the major weaknesses in these pictorial descriptions. Based on the findings, a new concept called '3-D Sustainability' has been developed and is presented visually as well as is described in the text. This concept introduces and ranks criteria for the assessment of hierarchies within, and conflicts of interests between, social, environmental and economic sustainability (the three dimensions of sustainability). These criteria are applied to several existing hierarchies and solutions to conflicts of interests. Based on the SWOT analyses, the main shortcomings of the widely used conceptual figures were identified as (1) misinterpretation of embeddings, (2) misjudgement of equity between the three dimensions of sustainability, (3) a lack of expression of limitations, and (4) lack of adequate decision support. These shortcomings are overcome (theoretically and in practice) by '3-D Sustainability', a slightly more complex, but conceptually richer, figure than the widely used conceptual figures assessed. In particular, the shift of the burden of proof within the three sustainability dimensions is argued as a main solution. The application of the criteria of '3-D Sustainability' to several real examples indicates its usefulness in decision support, while justifying more sustainable hierarchies and solutions in the settlement of conflicts of interests within the three sustainability dimensions. © 2007 Elsevier B.V.
