Measuring Value Creation Holistically Through Impact Accounting
Impact Accounting systematically captures the effects of economic activity and enables a holistic perspective on value creation beyond traditional metrics. In this way, societal and environmental impacts become an integral part of decision-making – for companies, the public sector, and the management of investment portfolios. This page provides an introduction to the key terms, concepts, and application areas of Impact Accounting.
What is Impact Accounting?
Impact Accounting refers to the measurement and valuation of a system’s social, environmental, and economic impacts. Such a system may, for example, be an organization, a project, or an investment decision. In contrast to traditional Financial Accounting, this approach considers external effects, such as environmental burdens, social risks, and value created for society.
Impact Accounting is part of a broader field of related concepts, including Impact Valuation, Capitals Accounting, True Cost Accounting, Integral Accounting, as well as Social Cost and Social Value.
Read here how leading companies use Impact Accounting to support credible reporting, transparent product impacts, prioritized actions, and impact-based investment decisions.
Goals of Impact Accounting
Impact Accounting aims to assess value creation in a comprehensive way. It systematically captures and analyzes social, environmental, and economic impacts within a common framework. To provide a consistent basis for decision-making, impacts are quantified and made comparable along transparent impact pathways. Results can also be translated into monetary terms to enable their integration into established reporting and steering approaches.
In this way, Impact Accounting reveals trade-offs between social, environmental, and economic impacts. It enables a consistent comparison of different options and supports the systematic evaluation of their overall impacts. This increases transparency and strengthens decision-making.
Methodological Foundations of Impact Accounting
Impact Accounting is suitable for analyses at company and product level, along value chains, as well as for investment projects and portfolios. The appropriate unit of analysis depends on the level at which decisions are made. Indicators that reflect different impact dimensions serve as the basis for the assessment. They are measured in physical units, such as greenhouse gas emissions in tons, land use in hectares, or water consumption in cubic meters. Examples of social impacts include training hours, taxes paid in euros, or the number of jobs supported.
Depending on the analytical objective, these measured impacts can be translated into monetary units using value factors. These factors account for the fact that the same indicator can have different societal consequences depending on the context. For example, water consumption has a greater impact in a dry region than in a water-rich area. Many environmental damages also become relevant only over time – for example when resource costs increase or when water becomes scarce due to competing uses such as food production. Impact Accounting captures these societal costs that are typically not reflected in market prices. This makes social, environmental, and economic impacts comparable and enables their integration into decision-making processes.
Depending on the unit of analysis and the research question, different methods are used:
Company, Portfolio, or Value Chain Level
Use of multi-regional input-output models (MRIO) to capture direct and indirect impacts along global supply chains, e.g., based on established MRIO databases (WifOR, EXIOBASE, GLORIA, OECD ICIO, or FIGARO). With WISIT, the WifOR Institute Sustainability Impact Tool, WifOR provides a SaaS solution for this purpose.
Product Level
Analysis of product impacts, e.g., through the application of Value Factors in combination with life cycle assessments (LCAs). Additional scientifically grounded research approaches can be applied to examine specific impact dimensions, such as the social impact of medical innovations.
Public-Private Collaboration
Benchmarks and impact intensities enable the comparison of impacts across countries and industries. This supports the evaluation of different courses of action and promotes integrated decision-making among stakeholders such as municipalities, companies, and civil society.
Frameworks and the Impact Accounting Ecosystem
Impact Accounting is part of a growing international ecosystem. Various initiatives and organizations are working to further develop and gradually harmonize common terminology, methodological foundations, and applicable standards. The aim is to make Impact Accounting easy to apply in business practice, policymaking, and financial markets.
Key players currently contributing significantly to standardization include:
Other relevant initiatives include:
There are also platforms that make impact information for portfolios accessible – a relevant aspect for investors. For example:
In addition, complementary standards and frameworks are increasingly emerging, including ISO 14054 “Natural capital accounting for organizations – Principles, requirements and guidance” as well as the methodological convention of the German Environment Agency (UBA) for valuing environmental costs.
Institutional Integration and Application of Impact Accounting at the EU Level
The methodological foundations of Impact Accounting are currently being advanced in several European initiatives. Their aim is to systematize approaches to assess environmental and social impacts. The central question is how Impact Accounting can be consistently integrated into corporate management as well as economic and environmental policy processes.
A key example is the Capitals Coalition’s EU Transparent Project. It examines how Value Factors are used in practice and what prerequisites are necessary for their broader application in management and decision-making.
Further initiatives are emerging within the Organisation for Economic Co-operation and Development (OECD), such as the Environmental Impact Valuation (ENIVADE) project, as well as at the national and European levels, including those related to research projects of the German Federal Environment Agency (UBA) and activities of the European Commission focusing on small and medium-sized enterprises (SMEs).
WifOR is closely involved in this development and collaborates with international initiatives, including the Capitals Coalition and the OECD, to further advance impact accounting methodologies.
Approaches to Implementing Impact Accounting – How WifOR Supports Companies, Investors, and Public Actors
WifOR supports companies, investors, and public actors in implementation – depending on the issue at hand, data availability, and organizational maturity – through individual projects, standardized data packages, and WISIT as an impact accounting tool.
Which approach is best suited to your needs? Please feel free to get in touch to discuss your case with us!
1. Individual Impact Accounting Projects
Customized projects are particularly suitable when organizations or decision-makers have limited experience with Impact Accounting. Depending on the analytical question, impacts can be measured and assessed at the company or portfolio level as well as for individual products or projects. Such projects can also be used to analyze highly specific decisions, for example those relating to infrastructure projects or product alternatives.
Depending on the question, different analytical methods are used to assess impacts. To determine impacts along global supply chains, WifOR uses (among other approaches) extended, multi-regional input output models (MRIO). At the product level or in comparisons of locations and projects, the analyses are often supplemented by product-specific data and life cycle assessments (LCAs).
2. Standardized Data Packages and Value Factors
WifOR provides the following data packages for measuring impacts:
These multipliers can be used in the same way as spend-based GHG accounting.
Value Factors are available from sources such as:
- WifOR Institute
- Capitals Coalition – Value Factors
- IFVI – Environmental Topic Methodologies (hosted by Capitals Coalition)
- Valuing Impact
- GIST Impact
- UBA Method Convention
- Global Value Exchange
- Environmental & Social Value Database (ESVD)
3. WISIT – the WifOR Institute Sustainability Impact Tool
WISIT is a web-based analysis tool that helps organizations apply Impact Accounting in practice. Using WISIT, organizations can measure their supply chain impacts or assess the societal effects of investments. The tool provides results both in physical units and in monetized terms.
This information provides a solid foundation for comparing different options and making evidence-based decisions. Furthermore, the results can be used directly for reporting and communication with stakeholders.

Impact Accounting enables various stakeholders to integrate social, environmental, and economic impacts into decision-making. The following examples illustrate the most important application areas for companies, investors, and public actors.
1. Explaining Impact Clearly and Reporting Credibly
The same sustainability indicator can have very different societal impacts depending on regional conditions. For example, land use in areas of high importance for biodiversity and water availability has more critical consequences than in regions of lower ecological and economic significance.
Impact Accounting makes such differences visible: impacts are assessed in context and translated into a common metric using value factors. This allows organizations to systematically compare indicators such as water consumption, land use, or social impacts, identify trade-offs, and derive data-driven priorities.
Practical Examples
Integrated Reporting
Novartis shows how social, environmental, and economic impacts can be structured and communicated consistently.
External Communications
Roche applies the “Society – Environment – Economy” framework to clearly demonstrate its contributions to employment, economic value creation, and societal impact in political and public discourse.
Investor Relations
Impact Accounting is also gaining importance in capital market communications, as it allows to translate impacts into monetary units and present them in a comparable manner – for example, in the BASF Factbook.
2. Product impact: Communicating benefits and societal effects
At the product level, Impact Accounting helps communicate impacts in a way that makes benefits and trade-offs between dimensions transparent. This involves considering not only negative externalities (e.g., emissions or resource consumption) but also, depending on the product, its social and economic value – for example, for patients, healthcare systems, and society.
Methodologically, two components can be combined:
- Product externalities are captured using life cycle assessment (LCA, “cradle-to-grave”) and monetized using Value Factors – for example, for CO₂, water, waste, or air pollutants.
- Socioeconomic benefits can be derived additionally via impact mechanisms such as health gains – for instance, by translating QALYs (Quality Adjusted Life Years) into productive time, avoided costs, and macroeconomic effects.
This creates a consistent picture of a product’s overall impact, enabling product comparisons, prioritization of innovations, and transparent communication with stakeholders. Furthermore, the results can be compared to the product costs as the Social Rate of Return on Investment. This provides a clearer basis for assessing different products or treatment options.
Practical Examples
Measuring Environmental Impact
Everpure (formerly Pure Storage) demonstrates how Impact Accounting can be applied to data centers to make environmental impacts comparable. This involves translating operational data (e.g., energy demand, cooling, IT configuration, location) into physical as well as monetized environmental impacts. This supports public and private decision-making for future-ready digital infrastructure (VBA 5th Pilot Study, December 2025, pp. 18-19).
Quantifying Health Impact
A social impact analysis of early intensified treatment for patients with type 2 diabetes in Mexico demonstrates how societal benefits can be measured and expressed monetarily. The results include 13,500 avoided disease events, 13 million additional productive hours, and a social impact of $54 million. The study (2022) was published in the Journal of Comparative Effectiveness Research.
3. Steering and Prioritization of Measures
Impact Accounting helps companies address regulatory requirements in the context of the EU Green Deal in a structured way. Using a spend-based approach, materiality assessments and risk identification within due diligence activities can be carried out on a consistent basis.
First, Impact Accounting enables data-driven materiality assessments under the Corporate Sustainability Reporting Directive (CSRD). Monetized sustainability indicators make different impact dimensions comparable and facilitate consistent prioritization. Sustainability benchmarks, differentiated by industry and country, provide reference values that help contextualize an organization’s results and support a robust assessment of materiality.
Second, Impact Accounting captures impacts and risks along upstream value chain stages and supports organizations in meeting supply chain due diligence requirements. Hotspot analyses and supplier screenings reveal the countries, industries, and product groups where the greatest impacts and risks occur, enabling targeted prioritization of measures.
Practical Examples
Materiality Assessment
Monetized impact data supports the evidence-based prioritization of key issues and enables their classification within the industry context. Mitsubishi Chemical uses, among other things, the industry benchmarks from WifOR and the Value Balancing Alliance for this purpose – read more here.
Hotspot Analysis and Supplier Screening
Impact Accounting enables organizations to systematically identify and prioritize key impacts along the value chain. In this case study, SAP describes how the company uses Impact Accounting to identify key sustainability topics and risk areas (so-called hotspots) based on data and integrate them into management processes.
4. Investors and Development Banks: Evaluating Portfolios and Investments by Impact
Investors and development banks rely on robust impact information to direct capital toward the areas where it creates the greatest societal value. Impact Accounting delivers the transparency and comparability they need. It empowers institutions to evaluate even complex portfolios not only by their financial performance, but also by the environmental and social value they generate.
Practical Examples
Impact Investing
Impact Accounting enables the systematic evaluation of portfolios and programs in terms of value creation, employment, environmental, and social effects. The Hellenic Development Bank used this approach to transparently quantify the societal contribution of its activities – read more here.
Data-driven Investment Decisions
With Impact Accounting, investments can be systematically assessed and compared in terms of their societal impacts. In this example, WifOR illustrates how the method is used to quantify the impact of capital investments and to support data-driven investment decisions – read more here.
