The IS Rating Scheme is Australia and New Zealand’s rating framework to assess the sustainability of the planning, design, construction and operation phases of infrastructure programs, projects, networks and assets. IS evaluates the sustainability performance of the quadruple bottom line (governance, economic, environmental and social) of infrastructure development. Several manuals and resources are available, covering different phases of the infrastructure cycle, being the main ones IS Design & As Built v2.0 and IS Planning v2.0. The total score is calculated based on the points achieved in the different credits. Verification of the assessment result is undertaken by an independent third-party verifier.

The Infrastructure Voluntary Evaluation Sustainability Tool (INVEST) is a web-based self-evaluation tool to assess and enhance the environmental, social and economic sustainability of transportation projects. The tool aims to support a sustainable construction and maintenance of highways and other transportation projects to satisfy societal development and economic growth while enhancing the natural environment and reducing natural resource use. The tool offers four different modules throughout the life cycle: System Planning for States (SPS), System Planning for Regions (SPR), Project Development (PD) and Operations and Maintenance (OM). Each module is independent, measures sustainability across individual criteria and is evaluated separately.

The Green Rating for Integrated Habitat Assessment (GRIHA) is India’s national framework for the assessment of environmental impacts of built environments with an individual version applying to large developments (>50Ha) (GRIHA-LD) and one for Cities. For both versions, the net impact of built environments on quantitative and qualitative parameters is totaled and compared against a rating table, resulting in a sustainability certification. Thereby, the tool aims to support the reduction of detrimental impacts of built environments on ecological cycles and surroundings.

The Global Sustainability Assessment System (GSAS) is a performance-based system developed for rating green buildings and infrastructures. The primary objective of GSAS is to create a sustainable built environment that minimizes ecological impacts and reduces resource use, considering the specific needs and context of the Middle East and North Africa regions (MENA). The system offers three different certifications: (1) GSAS Design & Build; (2) GSAS Construction Management; and (3) GSAS Operations. All certification procedures include an initial assessment followed by an audit.

Envision is a flexible system of criteria and performance objectives to aid decision makers and help project teams identify sustainable approaches during planning, design and construction of infrastructure projects that will continue throughout the project’s operations and maintenance and end-of-life phases. The Envision system consists of different components: (1) The Envision Pre-Assessment Checklist can be applied early-phase and used to prepare later sustainability assessments; (2) the Envision Online Scoresheet provides for a detailed online self-assessment; (3) the Envision Verification provides for an independent third-party project review process; (4) the Envision Awards offer recognition for qualifying verified projects.

CEEQUAL Projects assists in delivering improved sustainability performance and strategy of infrastructure projects. Projects are assessed across a range of management, environmental and social criteria, using the CEEQUAL Online Assessment Tool. The individual version for Term Contracts has been specifically created for the sustainability assessment of civil engineering and public realm works that are undertaken through contracts over several years, offering two question sets, one for maintenance works and one for new works. Assessments are conducted by CEEQUAL-trained assessors and verified by CEEQUAL-appointed external verifiers (in case of Term Contracts in the first and penultimate years including yearly surveillance visits).
