ESG Data Demystified: What Organisations Need to Monitor

The compliance landscape has undergone a fundamental transformation. In France, corporate directors now face up to five years imprisonment and €75,000 fines for obstructing ESG audits. California’s Air Resources Board has set an August 2026 deadline for emissions reporting affecting 2,500 companies. ESG data, the quantifiable metrics measuring environmental, social and governance performance, has shifted from voluntary exercise to regulatory imperative. For organisations navigating this terrain in 2025, understanding precisely which metrics to track determines not merely compliance success but competitive survival.

The regulatory convergence tells an unambiguous story. The EU’s Corporate Sustainability Reporting Directive will eventually mandate comprehensive sustainability disclosures from over 50,000 organisations. Singapore and Hong Kong adopted International Sustainability Standards Board frameworks requiring Scope 1 and 2 greenhouse gas disclosures from listed companies in 2025, with Scope 3 following by 2027. China’s CSRC launched mandatory ESG disclosure pilots for A-share listed companies effective March 2025. This global alignment means ESG data collection has evolved from optional reporting to strategic necessity.

Environmental Data: The Three Pillars

Environmental ESG data encompasses far more than carbon accounting, though emissions tracking forms the foundation. Organisations must simultaneously monitor energy consumption, water stewardship and waste management with precision matching financial reporting standards.

Carbon Emissions: Scope 1, 2 and 3

The Greenhouse Gas Protocol establishes three distinct emission scopes that organisations must track. Scope 1 captures direct emissions from sources owned or controlled by the company, including on-site boilers, furnaces and company vehicles. For a logistics operator, this means fuel combustion in owned delivery fleets. A chemical plant measures process emissions from industrial reactions.

Scope 2 accounts for indirect emissions from purchased electricity, steam, heating and cooling. The EPA’s eGRID provides region-specific emission factors that organisations use to convert kilowatt-hours into carbon dioxide equivalent emissions. A data centre purchasing 100,000 megawatt-hours annually in a coal-dependent grid region generates substantially higher Scope 2 emissions than an equivalent facility sourcing renewable power.

Scope 3 encompasses all other indirect emissions throughout the value chain. The GHG Protocol defines 15 categories spanning purchased goods, business travel, employee commuting, use of sold products, and end-of-life treatment. For technology companies, Scope 3 frequently accounts for over 90% of total emissions, primarily from component manufacturing at supplier facilities and electricity consumption during product use.

Current disclosure rates reveal significant gaps. Only 9% of nearly 2,000 companies surveyed in 2024 comprehensively report emissions across all three scopes. This matters because Scope 3 emissions typically represent the largest portion of carbon footprints, particularly for retail, technology and financial services sectors where value chain emissions dwarf direct operational impacts.

Energy and Water: Consumption Metrics

Beyond carbon, organisations measure total energy consumption in megawatt-hours, disaggregating usage between fossil fuels and renewables. Energy intensity metrics, calculated as consumption per unit of revenue or production output, enable meaningful year-over-year comparisons that account for business growth. The renewable transition requires tracking the percentage sourced from solar, wind, hydroelectric and other renewable sources.

Water management constitutes an equally critical pillar. U.S. industrial facilities consume over 18.2 billion gallons of water daily, while private sector water disclosures have risen 85% over five years as 680 investors managing $130 trillion requested detailed water information through CDP questionnaires in 2022.

Organisations track water withdrawal by source, distinguishing between surface water, groundwater, seawater and municipal supplies. Total water consumption, calculated as withdrawal minus discharge, indicates actual resource depletion. Water intensity metrics normalise consumption against production volumes. For water-intensive sectors, these metrics carry particular weight. Brewing operations consume 2.3 to 5.3 litres of water per litre of beer produced. Companies operating in water-stressed regions face heightened scrutiny, with stakeholders expecting detailed risk assessments and mitigation strategies.

Waste and Circular Economy

Waste generation measured in metric tonnes forms the baseline, categorised by hazardous versus non-hazardous composition. The waste diversion rate measures the percentage redirected from landfills through recycling, composting or energy recovery. Achieving diversion rates above 50% signifies effective management, while industry leaders reach 75% to 90%. Europe’s packaging waste recycling reached 65% in 2022, while overall waste excluding minerals maintained 44% recycling rates.

Circular economy metrics extend beyond recycling. The circular input rate measures secondary materials as a percentage of total material input. The Material Circularity Indicator assesses both input and output flows, scoring recycled or renewable inputs alongside products cycled back into the economy at end-of-life. Material recovery rates track how effectively organisations recover valuable materials from products, while product lifespan extensions demonstrate commitment to resource efficiency.

Social Data: People and Communities

Social ESG data encompasses how organisations treat people across their sphere of influence, from direct employees to supply chain workers to affected communities.

Workforce Diversity and Pay Equity

Organisations track representation across gender, ethnicity, age and disability status, broken down by organisational level from entry positions through senior leadership. Among S&P 500 companies, workforce diversity disclosures declined in 2025, with reporting women in management down 16 percentage points amid legal and political scrutiny. Despite disclosure pullbacks, diversity tracking remains essential. Organisations in the top quartile for gender diversity on leadership teams show 25% higher probability of above-average profitability.

Effective diversity metrics examine representation at every level. Salesforce’s 2024 reporting shows women comprised 36.1% of worldwide employees, yet representation varied significantly by job family and seniority. Pay equity analysis examines compensation fairness, with U.S. women earning 85% of what men earned on average in 2024, though the gap narrows to 95% for workers aged 25 to 34.

Safety, Wellbeing and Development

Lost time injury rates, calculated as injuries resulting in time away per million hours worked, serve as standard performance indicators. Total recordable incident rates capture broader safety performance including medical treatment cases. Employee wellbeing extends to mental health support programmes and work-life balance metrics.

Human capital development metrics track training hours per employee, development expenditure per capita and internal promotion rates. Employee retention rates, calculated overall and by demographic segment, reveal disparities in experience. Turnover cost savings average 1.5 to 2 times annual salary per prevented departure.

Supply Chain Labour Practices

Supply chain audits verify compliance with labour standards, documenting working conditions, wages relative to living wage benchmarks, and working hours. Organisations report the percentage of suppliers audited annually, audit findings categorised by severity, and corrective action closure rates.

Human rights due diligence has evolved to mandatory requirement under frameworks like the EU’s Corporate Sustainability Due Diligence Directive. Companies assess risks of forced labour and child labour throughout value chains, with particular attention to high-risk geographies and industries like agriculture, garment manufacturing and electronics assembly.

Governance Data: Leadership and Accountability

Governance ESG data evaluates how organisations are led, managed and held accountable, providing investors with insights into decision-making quality and risk management.

Board Composition and Executive Compensation

Board composition metrics track the percentage of independent directors, gender and ethnic diversity among board members, and separation of chair and CEO roles. Director expertise relevant to material ESG issues demonstrates board capacity to oversee sustainability performance. Among S&P 500 companies in 2025, the share disclosing aggregate female director numbers fell 30 percentage points following legal rulings including the Fifth Circuit’s decision striking down Nasdaq’s board diversity listing rule.

Executive compensation structures receive intensive scrutiny. Organisations disclose CEO-to-median-worker pay ratios, alignment between executive pay and long-term performance, and integration of ESG metrics into compensation plans. Three-quarters of S&P 500 companies now embed ESG metrics into leadership compensation, with diversity, climate objectives and safety performance most commonly featured. However, 2025 witnessed sharp declines in diversity-linked executive pay incentives amid legal concerns.

Ethics, Compliance and Transparency

Anti-corruption policy implementation, measured through training completion rates, demonstrates commitment to ethical conduct. Whistleblower mechanisms track reporting channel availability, case volumes and resolution timeframes. Data security practices gain prominence for technology and financial services firms, with organisations reporting cybersecurity incident frequency and data breach responses. Third-party assurance of ESG data and public disclosure of sustainability strategies demonstrate accountability.

Industry-Specific Materiality

Material ESG data differs fundamentally across industries. Oil and gas companies face scrutiny on emissions intensity, renewable energy investment percentages and methane leak programmes. Technology firms prioritise data centre power usage effectiveness, electronic waste recycling rates and content moderation metrics. Financial institutions track sustainable finance portfolios as percentages of total assets, climate risk integration in lending decisions and financial inclusion metrics. Pharmaceutical manufacturers focus on drug pricing, clinical trial diversity and access to medicine initiatives. Each sector’s material issues reflect unique ways ESG factors intersect with business models.

Implementation: Infrastructure and Costs

Collecting comprehensive ESG data presents formidable operational challenges. Information resides across disparate systems with facilities management databases tracking energy, human resources platforms maintaining diversity metrics, and procurement systems holding supplier information. Organisations lacking integrated infrastructure struggle with accuracy, consistency and timeliness.

CSRD compliance will impose significant costs requiring investments in data collection systems, reporting platforms and third-party assurance services. The ESG reporting software market, valued at $1.18 billion in 2025, is projected to reach $4.97 billion by 2035. Companies typically achieve break-even on ESG software investments within 12 to 18 months through reduced manual reporting costs and improved regulatory compliance.

Data quality concerns persist. Unlike financial data backed by centuries of accounting standards, ESG data collection methodology remains relatively immature. Estimation techniques for unavailable data, incomplete supplier information and evolving measurement protocols introduce uncertainty. Organisations must develop documentation matching the rigour of financial controls.

The Stakes: Why This Matters Now

The consequences of inadequate ESG data management extend far beyond regulatory penalties. France imposes up to €75,000 fines and five-year imprisonment for corporate directors obstructing CSRD audits. EU member states maintain discretion to impose additional sanctions, with suspension of trading or corporate registration possible.

Beyond legal repercussions, ESG data quality increasingly determines access to capital. BlackRock, Vanguard and other major institutional investors now systematically assess ESG scores before investment decisions, with poor performance triggering portfolio exclusion or higher cost of capital. Banks integrate climate risk into lending decisions, potentially declining financing for companies with high environmental exposures and weak mitigation strategies.

Supply chain dynamics amplify these pressures. Large enterprises increasingly require suppliers to provide detailed ESG data as condition of contract renewal. Non-compliant suppliers risk losing major contracts, creating cascading requirements throughout value chains. Small and medium enterprises represent the fastest-growing ESG software segment, expanding from 32% market share in 2025 toward projected 40% by 2035.

Talent acquisition increasingly hinges on ESG performance. Younger workers prioritise employer sustainability commitments, with many willing to accept lower compensation to work for organisations demonstrating genuine environmental and social commitment. Companies with strong ESG reputations attract higher quality candidates and retain diverse talent more effectively.

The path forward requires treating ESG data with rigour matching financial reporting. Organisations must invest in integrated data infrastructure enabling automated collection across disparate sources. Cross-functional collaboration between sustainability, finance, legal, operations and human resources teams ensures comprehensive coverage and data quality. Companies approaching ESG data as strategic asset rather than compliance burden will secure competitive advantages in capital markets, talent acquisition and customer relationships as stakeholder expectations continue rising throughout this decade.
