Learn how organisations measure sustainability with clear KPIs, metrics, and global frameworks. See how companies track their impact and turn data into real action.
Sustainability is no longer a side initiative. It’s a core part of how modern businesses compete, grow, and stay resilient. To turn ambition into progress, companies need to measure what matters. That means tracking emissions, analysing supply chains, evaluating social impact, and translating goals into metrics. Done well, sustainability measurement isn’t just a compliance exercise—it drives innovation and builds long-term value.
In this guide, we’ll break down the frameworks, KPIs, and global standards that help organisations measure sustainability with clarity and consistency. Whether you're curious about ESG reporting or interested in a role in sustainable business, this explainer covers the essentials.
Why Measuring Sustainability Matters
The business case for sustainability
Sustainability has evolved from being purely reputation management to a driver of performance. Tracking data—like carbon emissions, energy use, and workforce diversity—helps organisations anticipate regulation, attract talent, and meet investor expectations. In a world where proof of impact drives trust, data has become the new currency of credibility.
Measuring effectively:
- Builds trust through transparency
- Helps manage risks
- Aligns business strategy with long-term value
- Guides decision-making with real-time insight
Transparency and accountability over greenwashing
Measuring sustainability is also the best defence against greenwashing. Vague promises without evidence can quickly erode trust.
Regulators and investors now require standardised disclosures of climate risks and ESG (environmental, social and governance) performance, often verified by independent audits.
Clear, consistent data gives credibility to commitments. It allows stakeholders to assess progress and hold leaders accountable. To measure sustainability effectively, organisations rely on key performance indicators (KPIs), frameworks, benchmarks, and certification systems
Core Frameworks for Sustainability Measurement
Triple Bottom Line: People, Planet, Profit
The triple bottom line expands reporting beyond profit to include social and environmental performance. Organisations track their impact on people (equity, labour rights, community) and the planet (carbon, water, biodiversity) alongside profit.
Choosing between GRI, SASB and ISO standards
Reporting frameworks make sustainability data meaningful and comparable. Among the most widely used are:
- GRI (Global Reporting Initiative): the most widely adopted. It provides hundreds of indicators across environmental, social, and governance areas. GRI is often chosen by multinational companies that need broad disclosures to communicate with diverse stakeholders.
- SASB (Sustainability Accounting Standards Board): its strength lies in sector-specific KPIs designed with investors in mind. For example, energy companies report on reserves and carbon intensity, while apparel companies report on labour practices and supply chain transparency. SASB makes data more relevant for capital markets.
- ISO standards: rather than reporting guidelines, ISO standards set out processes and practices that companies can certify against. ISO 14001 focuses on environmental management systems, ISO 26000 on social responsibility.
Many firms combine these frameworks—GRI for transparency, SASB for investor relevance and ISO for operational credibility. The key is aligning reporting tools with strategic objectives and the audiences that matter most.
The role of Life Cycle Analysis (LCA)
While frameworks set boundaries, Life Cycle Analysis (LCA) explores depth. It evaluates a product’s environmental footprint from raw materials to end-of-life, identifying where interventions have the greatest effect—design, materials, transport or recycling. LCA prevents burden-shifting between stages, ensuring that solutions reduce overall impact rather than moving it elsewhere.
Key Metrics for Measuring Sustainability
Environmental metrics: carbon, water and waste
When it comes to sustainability, environmental metrics remain central. These KPIs measure a company's pressure on natural resources and the climate:
- Carbon Footprint: Measured in tonnes of greenhouse gas emissions (GHG), categorised into: Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased energy), and Scope 3 (all other indirect emissions in the value chain, like supply chain or employee travel).
- Water Usage: The total volume of water withdrawn, consumed, and discharged, with increasing focus on usage in water-stressed regions.
- Waste Generation: The total amount of solid or hazardous waste generated, focusing on reducing landfill waste and driving the circular economy.
Social Metrics: Equity, Inclusion and Impact
These measure a company's commitment to its people and communities:
- Diversity & Inclusion: Metrics tracking the representation of different demographics (gender, ethnicity) across various organisational levels, particularly in leadership.
- Health and Safety: Tracking the lost-time injury rate (LTIR) to assess workplace safety performance.
- Supply Chain Labour: Monitoring working conditions, wages, and human rights diligence across the entire supply chain.
Governance Metrics: Ethics and Accountability
These assess the mechanisms of leadership, compliance, and ethical conduct:
- Board Structure: Metrics on the independence and diversity of the board of directors.
- Anti-Corruption: Policies and training hours dedicated to anti-bribery and corruption compliance.
Together, these environmental, social and governance pillars form the ESG structure, the standard language of sustainability reporting. They also mirror the four dimensions of sustainability: economic, environmental, social and governance.
How Sustainability Measurement Shows Up in the Real World
You don’t have to look far to see measurement in action. Leading companies across industries are using sustainability data not just to report, but to drive business decisions. These examples demonstrate how investing in sustainability can create a competitive advantage and illustrate that green finance can also effectively respond to the climate emergency.
Ingka Group: Emissions and Growth in Harmony
Since 2016, Ingka Group has reduced its climate footprint by 30%. This wasn’t done through offsets or vague pledges. It was the result of measurable actions: retrofitting buildings, switching to renewable energy, and tracking carbon emissions across operations. All while continuing to grow revenue. Their example proves that climate goals and commercial success can coexist—when strategy is backed by data.
Walmart: Procurement as a Carbon Lever
Walmart’s “Project Gigaton” aims to cut one billion metric tonnes of emissions across its supply chain. To get there, it developed supplier scorecards and tracked progress across thousands of partners. This is sustainability at scale, and it’s made possible by investing in systems that can track impact, not just set goals.
Unilever: Linking KPIs to Supply Chain Efficiency
Through its Sustainable Living Plan, Unilever set specific targets tied to metrics like water usage, energy consumption, and responsible sourcing. The result? A more efficient supply chain, reduced costs, and stronger customer loyalty. Unilever demonstrates how clear KPIs can unlock innovation, not just reduce impact.
Patagonia: Purpose-Driven, Data-Supported
Patagonia’s brand is built on environmental values. But behind the mission are real numbers. The company rigorously measures its material inputs, emissions, and fair trade sourcing practices. It publishes detailed impact reports and uses Life Cycle Assessments (LCA) to guide design decisions. By showing its work, Patagonia turns sustainability from a marketing claim, and the company’s values-based approach has built one of the most loyal customer communities in retail.
Global Indicators and Benchmarks
UN SDGs and the Human Development Index
The UN’s 17 Sustainable Development Goals (SDGs) offer a shared global framework—from clean energy and education to gender equality. Many organisations now map their initiatives to SDG targets to demonstrate alignment with international priorities.
At the national level, the human development index (HDI)—which combines data on health, education and income—highlights the broader social and economic context in which businesses operate.
Environmental performance and ecological footprint
The environmental performance index (EPI) ranks countries on issues such as air quality, biodiversity and climate action.
The ecological footprint measures how much natural capital is consumed compared with what the planet can regenerate. These benchmarks remind companies that sustainability performance must be viewed within planetary boundaries, not in isolation.
Auditing and certifications: ISO, CDP, GRI
Independent verification builds trust. Certifications such as ISO 14001, the Carbon Disclosure Project (CDP) and GRI audits ensure that reported data is accurate and comparable. External validation turns self-reported numbers into credible evidence of progress.
Challenges and Gaps in Sustainability Measurement
Standardisation and comparability
Despite growing alignment, differences in boundaries and definitions still make comparisons difficult. One company might include supplier emissions, another might not, creating inconsistencies that reduce the usefulness of sustainability data for investors and regulators.
Data quality and timing
Sustainability data is only valuable if it is accurate and timely. Annual reports often leave decision-makers reacting to outdated information. To make sustainability truly strategic, organisations need continuous measurement, integrated analytics and real-time tracking systems.
Interdisciplinary approaches
Sustainability sits at the intersection of economics, science and society. Reducing emissions, for example, might improve environmental outcomes but affect employment in certain regions. A complete picture requires interdisciplinary collaboration, integrating environmental science, economics, and social research.
How Technology Improves Measurement
Real-time data and predictive analytics
Technology is transforming sustainability reporting from static to dynamic. Sensors, satellites, and IoT devices now monitor emissions, water use, and energy consumption in real-time. Predictive analytics adds foresight by:
- Forecasting resource needs
- Modelling climate risks such as floods and heatwaves
- Simulating long-term outcomes of business decisions
Automation and impact dashboards
AI-powered platforms automate data collection and analysis across complex operations and supplier networks, showing that digital support can indeed support a sustainable economy. They create dashboards that:
- Track progress against goals
- Flag emerging risks
- Visualise impact clearly for stakeholders
This automation reduces reporting burdens and improves transparency, giving environmental leadership better insight and stakeholders more trust.
