The 2012 State of the World Report drew widespread approval at the FIDIC conference in Seoul. The report focused “on the nature of decisions made by project teams, their impacts and some of the dimensions of sustainability that influence decision-makers” (FIDIC 2012, p.2). This included a global review of sustainability appraisal tools used to support infrastructure decisions. These tools were grouped into four main categories: rating and certification, decision-support, calculators and guidelines.
In early 2013 FIDIC requested an update of the various tools, in time for the Centenary conference in Barcelona in September. The purpose of this update was to provide a current and more in-depth assessment of the tools. This allows for an informed discussion of the state-of-play in the development of such tools at a global level. A number of relevant tools had not been identified in the 2012 report and there has been continuing development of others that were. Several additional examples included in this review were identified through feedback from the 2012 report and desktop research.
While the number of tools in this review has expanded, it is not a complete database. There are a plethora of tools that have some claim to sustainability in decision-making in the built environment; it would be a significant task to capture them all. This review does, however, act as a useful reference for industry. It provides an indication of the types of tools available around the world and helps to inform tool selection through providing basic information about the nature of the tools and how they are applied.
This update presents summaries of tools based on templates established for each of the four main categories. The content of these summaries is presented in Table 1. Headline banners (examples shown in Figure 1) provide a quick reference for comparing tools within a category. Information was collected primarily from the tool websites. Certifying organisations / developers of the rating and certification tools and decision-support tools were contacted to review draft summaries to ensure accuracy of information.
 Overall summary tables for each category indicate where a tool has not been reviewed.
