Sustainability expectations continue to influence how projects across the natural resources and infrastructure sectors are evaluated and delivered. To address these expectations, technical teams are looking for tools they can apply directly in project and operational work. This issue brings together articles focusing on some of the tools applied by SRK to achieve the sustainability objectives of our clients — these represent practical approaches used to support analysis, design, measurement, risk evaluation, and governance in real project settings.
In this issue, “tool” is used in a broad sense. Some contributions describe defined technical methods such as quantitative risk methods, modelling tools, projection inputs or analytical workflows. Others focus on structured assessment processes and governance mechanisms that help teams identify risks, compare options, and document decisions in a consistent and traceable way. Across the articles, the emphasis is on application: what the tool is, what it is used for, and how it is applied in practice.
Climate-related tools are presented through two complementary approaches. One describes global climate model outputs and data-driven methods for developing site-specific projections of precipitation, temperature extremes, and drought or wet periods to inform project planning. The other outlines a structured hazard and risk framework for evaluating climate-linked scenarios, estimating likelihood and consequence, and classifying risks to guide adaptation planning.
Tailings management is addressed through a separate set of risk and governance tools. One article explains the use of cost curves to express life-safety and consequence risk to compare different tailings facilities. Another examines risk-based tailings governance tools and the use of independent tailings review boards as oversight mechanisms to support consistency and accountability in tailings management.
A further group of articles focuses on decision-support and due-diligence tools. Multiple Accounts Analysis is presented as a structured method for comparing project alternatives. Cumulative impacts assessment is described as a tool used to evaluate combined effects beyond single-project boundaries. A collaborative human rights assessment approach is set out, involving a structured method used to identify who may be at risk, how impacts may occur, and where and when exposure may arise.
Water resource tools form another core theme. Articles describe water usage benchmarking, water stewardship approaches, and methods framing water as a material operational and sustainability factor. Technical contributions examine integrated surface water–groundwater modelling at catchment scale and the development of hydrogeological conceptual models as a foundation for water assessments, model design, and interpretation. Operational design approaches — including waste rock co-disposal — are also presented as tools with environmental performance implications in the realm of water quality.
Environmental and renewable energy projects are addressed through applied modelling and assessment tools used for siting and impact evaluation. One case study describes habitat modelling to inform design - as one of the first wind farms planned in its region, the project serves as a reference case for integrating biodiversity science into infrastructure siting through spatial analysis. Additional articles cover environmental noise software tools and visual impact assessment tools, including glare and shadow flicker modelling.
Measurement and accounting tools are addressed through an article on greenhouse gas inventory development. The contribution outlines practical challenges commonly encountered in emissions accounting — including data quality, boundary definition, and consistency across diverse operations — and describes structured calculation workflows that support standardized emission factors and alignment with established reporting frameworks.
Taken together, these articles present sustainability tools as working components of technical practice across geoscience, engineering, environmental, and social disciplines. The contributions emphasize method, transparency of assumptions, and practical application across different project stages and operating contexts. The focus throughout the issue is on how tools are applied and interpreted in practice, so their relevance can be considered in planning and operational decision-making.
