A sustainability lead at a mid-sized manufacturer once told me she was drowning. Her team tracked more than 200 data points, yet her board still could not answer one simple question: are we actually improving? That gap is common. The fix is not more data. It is the right data.
If you are deciding which ESG metrics and KPIs to track, this guide gives you 15 that matter most, the units to measure them in, the frameworks they map to, and a simple way to track them without burning out your team.
What Are ESG Metrics and KPIs? (Quick Definition)
ESG metrics are measurable values that show how a company performs across environmental, social, and governance topics. ESG KPIs are the smaller, strategic set of those metrics that are tied to specific goals and used to make decisions.
In short, every KPI is a metric, but not every metric earns the title of KPI. Good ESG KPIs share a few traits. They are specific, measurable, time-bound, comparable across years and peers, and material to your stakeholders.
This matters more every year. According to the Governance & Accountability Institute, 99% of S&P 500 companies published a sustainability report for 2024, a record high. Reporting is now the norm, so the quality of your metrics is what sets you apart.
ESG Metrics vs KPIs: What Is the Difference?
Think of metrics as your full dashboard and KPIs as the gauges you actually watch while driving.
A metric like "total water withdrawn" is useful background. It becomes a KPI when you attach a target, like "cut water use 15% by 2027 in high-stress regions." The target turns a number into a management tool.
The practical rule: track many metrics for completeness, but elevate only the handful that drive real decisions into KPIs your leaders review.
15 ESG Metrics and KPIs Companies Should Track
Here are the core environmental, social, and governance metrics that show up across major frameworks and investor questionnaires.
Environmental KPIs
Scope 1 emissions: direct greenhouse gas emissions from owned sources, in metric tons of CO2 equivalent.
Scope 2 emissions: indirect emissions from purchased electricity, heat, or steam.
Scope 3 emissions: value-chain emissions from suppliers, logistics, and product use, usually the largest and hardest to measure.
Energy intensity: energy used per unit of output or per dollar of revenue.
Water usage and recycling: total consumption and percentage reused, with focus on water-stressed sites.
Waste diverted from landfill: share of waste recycled, reused, or composted.
Social KPIs
Workforce diversity: representation by gender, race, and ethnicity across levels.
Employee turnover and retention: voluntary turnover rate and retention of key talent.
Health and safety: recordable injury rate and lost-time incidents.
Training and development: average training hours per employee.
Community investment: dollars or volunteer hours contributed to local programs.
Governance KPIs
Board diversity and independence: share of independent directors and gender balance.
Ethics and anti-corruption: completion rate of ethics training and number of reported incidents.
Data privacy and cybersecurity: breaches reported and time to resolve them.
Executive pay linked to ESG: whether leader bonuses are tied to sustainability targets.

How to Measure and Track ESG Performance
Knowing the metrics is half the job. Tracking them well is the other half.
Start With a Materiality Assessment
A materiality assessment is a structured process to find which ESG issues most affect your business and your stakeholders. It stops you from tracking everything and helps you focus your KPIs.
A retailer and a software firm will land on very different lists, and that is exactly the point.
Quantitative vs Qualitative Metrics
Quantitative metrics are numbers you can audit, like total emissions or injury rates. Qualitative metrics capture things numbers miss, like whether a supplier code of conduct exists or how the board oversees climate risk.
Strong ESG reporting uses both. Numbers prove performance, while policies prove intent and structure.
Data Collection, Tools, and Reporting Cadence
Set clear data collection rules so every site measures the same way. Spreadsheets still work for small programs, but many companies move to dedicated ESG software as data grows.
Most teams benefit from tracking quarterly and reporting once a year. That rhythm keeps data fresh without overwhelming staff.
Which ESG Reporting Framework Should You Use?
The three names you will hear most are GRI, SASB, and the ISSB.
GRI focuses on your impact on the world and a broad set of stakeholders.
SASB focuses on industry-specific issues that affect financial performance, which investors love. It covers five dimensions and 26 issue categories.
ISSB (the IFRS S1 and S2 standards) is the emerging global baseline that folds in the older TCFD climate guidance.
Many US companies use SASB and ISSB for investors and GRI for broader stakeholder reporting. They complement each other rather than compete.
ESG Reporting Rules in the US (2026)
US rules are shifting fast, so know what is mandatory versus voluntary.
California leads with two laws. SB 253 requires companies doing business in the state with more than $1 billion in revenue to report Scope 1 and 2 emissions, with Scope 3 following later. SB 261 asks companies above $500 million in revenue to publish climate-related financial risk reports.
According to legal updates tracking the California Air Resources Board, timelines and enforcement have faced litigation and adjustments, so check the latest status before you finalize your plan. Federal SEC climate rules have also seen delays, which makes voluntary frameworks even more useful as a foundation.
Common ESG Tracking Mistakes to Avoid
Even good teams trip over the same issues. Watch for these:
Greenwashing: reporting feel-good numbers without targets or proof.
Scope 3 double counting: the same emissions counted twice across the value chain.
Shifting boundaries: quietly changing what is included so trends look better.
Vanity metrics: tracking what is easy instead of what is material.
No assurance: numbers that were never independently checked.
A simple safeguard is to treat ESG data like financial data. If a number would not survive an audit, it is not ready to publish.
FAQ
A metric is any measurable ESG value. A KPI is a key metric tied to a target and used for decisions. All KPIs are metrics, but only the strategic ones become KPIs.
Scope 1, 2, and 3 emissions, workforce diversity, health and safety, board independence, and ethics compliance are core metrics most companies and investors expect to see.
They start with a materiality assessment, set consistent data rules, use spreadsheets or ESG software, then track quarterly and report annually against clear targets.
Most US companies pair SASB or ISSB for investor-focused reporting with GRI for broader stakeholder impact. The choice depends on your audience and industry.
Internal tracking works best quarterly, while public ESG reporting is usually done once a year, aligned with any regulations that apply to your business.
Conclusion
The companies that win at sustainability are not the ones with the most data. They are the ones that pick the right ESG metrics and KPIs, measure them honestly, and tie them to real targets. Start with materiality, build a focused set, map each KPI to a unit and a framework, and treat the numbers with the same care as your financials.
Pick your top ten KPIs this quarter and you will already be ahead of teams still drowning in spreadsheets.
