SDG-Aligned Environmental Resilience Impact Index (ERII)
The SICR elaborated the Environmental Resilience Impact Index (ERII) as a multidimensional analytical framework designed to assess the environmental performance of states, companies, and productive systems through an integrated resilience-oriented perspective. The central premise of the index is that environmental performance cannot be reduced to a single variable such as carbon emissions or water consumption, because the real environmental impact of an economic system emerges from the interaction between resources, production processes, governance choices, and long-term adaptive capacity. For this reason, the ERII is structured as a composite index that brings together five major dimensions: Water Sustainability, Energy and Emissions, Circular Resource Management, Pollution Control, and Environmental Governance and Strategy. Together, these dimensions aim to capture the systemic relationship between economic activity and environmental resilience, while also aligning the framework with the broader principles of the United Nations Sustainable Development Goals.
The index has been elaborated with a scientific approach in a research article, which is organized in a way that progressively builds the rationale for the index. It first situates the discussion within the broader field of sustainability assessment and environmental measurement, showing that many existing tools remain either too narrow, too descriptive, or too limited in their applicability to firms, sectors, and operational systems. In this context, the ERII is introduced as a response to the need for a more integrated and decision-oriented framework, capable of moving beyond fragmented metrics and toward a structured evaluation of environmental resilience. The paper then develops the scientific elaboration of the index, explains its five constituent dimensions in depth, and later presents a mathematical model through which the composite index can be calculated from normalized indicators and weighted dimensions. This structure gives the article both a conceptual and an operational character: it is not only a theoretical reflection on sustainability, but also an attempt to create a practical instrument for comparative analysis and strategic evaluation.
At the core of the article is the idea that resilience must be understood as more than environmental compliance. In the author’s framework, resilience refers to the capacity of an economic or productive system to reduce environmental pressure, adapt to ecological constraints, and maintain performance over time in the face of resource scarcity, regulatory shifts, climate variability, and changing sustainability expectations. This makes the ERII particularly relevant because it links environmental outcomes not only to resource use but also to strategic behavior, institutional quality, and long-term transformation. The article therefore positions the index as a tool that can support not just reporting, but also policy analysis, strategic planning, and performance benchmarking across different contexts.
The first major section devoted to the index concerns Water Sustainability, which is described as one of the foundational dimensions of environmental resilience. The article explains that water is a critical input for many productive systems, especially agriculture, manufacturing, and energy production, and that any meaningful environmental assessment must account for both the volume of water consumed and the quality of its management. In this sense, the Water Sustainability dimension evaluates how efficiently and sustainably economic activities use water resources, considering issues such as water consumption, water-use efficiency, recycling and reuse practices, and wastewater treatment effectiveness. The argument developed in the paper is that water sustainability cannot be measured merely through extraction volumes, because real resilience depends on whether systems can operate within ecological limits while also reducing vulnerability to scarcity and variability.
The article further deepens this dimension by adopting what it calls a broader hydro-strategic perspective. Water is treated not only as a physical input, but as a determinant of economic stability and long-term environmental resilience. This means that the ERII includes attention to water-related risk exposure, such as dependence on freshwater withdrawals, vulnerability to climatic fluctuations, water stress levels, and the regulatory or territorial constraints that shape access to water resources. Through this lens, water sustainability becomes dynamic rather than static: it is not only about present efficiency, but also about future viability under conditions of environmental pressure. The paper also emphasizes the relevance of Integrated Water Resource Management (IWRM) principles, arguing that water performance must be understood in relation to basin-level conditions, sectoral coordination, and broader governance thresholds. In other words, the article gives water a systemic and relational meaning, presenting it as a field in which operational efficiency, ecological balance, and public governance must converge.
The second dimension, Energy and Emissions, is presented as a critical component of the index because energy consumption remains one of the most powerful drivers of environmental degradation. In the article, this section focuses on the relationship between production processes, energy intensity, and greenhouse gas emissions, making clear that the environmental profile of a company or state depends heavily on how energy is sourced, consumed, and transformed into output. The ERII assesses the energy intensity of production, the share of renewable energy in the energy mix, and the volume of emissions generated per unit of activity. This allows the index to capture not only the current efficiency of energy use, but also the broader transition toward low-carbon production systems. The article makes it clear that this dimension is strongly linked to the climate agenda and to the need for aligning economic activity with sustainable energy pathways.
