Triple Bottom Line (TBL)
The triple bottom line (TBL) is an accounting and management framework that broadens the evaluation of a company’s performance beyond financial profit to include social and environmental outcomes. It captures three dimensions—people, planet, and profit—so organizations can assess their overall impact on society and the environment as well as their financial health.
Origin and purpose
TBL was introduced by British management consultant John Elkington in 1994. The intent is to shift business decision‑making away from profit‑only thinking toward a balanced approach that values social responsibility and environmental stewardship alongside financial results.

The three Ps
TBL emphasizes three interdependent pillars:
- Profit (or Prosperity)
- Traditional financial metrics: net income, margins, cash flow.
-
Also covers ethical earning and long‑term economic health for the company and its community (fair taxes, local economic investment, responsible payments to creditors and employees).
-
People
- Social impact on employees, suppliers, customers, and communities.
-
Typical measures: wages and benefits, workplace safety, diversity and inclusion, supplier diversity, community investments, and customer access/quality metrics.
-
Planet
- Environmental impacts and resource stewardship.
- Typical measures: greenhouse gas emissions, energy use, waste generation and recycling rates, water use, sustainable sourcing, and reductions from operational changes.
(Some organizations use “prosperity” instead of “profit” to emphasize long‑term, shared economic benefits.)

How to measure TBL
Measuring TBL requires combining conventional financial reporting with social and environmental metrics. Common approaches:
- Profit
-
Standard financial statements and additional disclosures (regional margins, historical tax payments, timely payments and penalties).
-
People
-
Quantitative and qualitative indicators: average wages and benefits, turnover, training hours, demographic breakdowns, supplier classifications, and community spending.
-
Planet
- Operational and lifecycle measures: emissions (scope 1–3 where possible), energy consumption, waste and recycling volumes, water use, and percentage of responsibly sourced inputs.
Challenges:
– Social and environmental indicators can be hard to quantify and compare across firms.
– Data collection and standardization may require new processes and external verification.
– Trade‑offs can arise when priorities conflict (e.g., cost reduction vs. environmental investment).

Advantages
- Encourages positive social and environmental outcomes alongside financial returns.
- Can improve employee engagement, retention, and recruitment.
- Attracts customers and investors who prioritize environmental, social, and governance (ESG) criteria.
- May produce long‑term operational efficiencies and reduce risks.
Disadvantages
- Non‑financial impacts are often difficult and costly to measure consistently.
- Potential conflicts among the three pillars can complicate strategy and resource allocation.
- Short‑term costs may rise when choosing more responsible suppliers, processes, or materials.
Examples of TBL application
Many firms integrate TBL principles into their strategies. Examples:
– Ben & Jerry’s: emphasizes fair trade, climate justice, and social mission in product sourcing and advocacy.
– LEGO: targets renewable energy use and sustainable materials, partnering with NGOs on conservation efforts.
– Mars: invests in sustainable cocoa programs and farmer support to improve livelihoods and supply‑chain resilience.
– Starbucks: implements hiring initiatives and community programs alongside environmental commitments.
FAQs
- What are the three elements of TBL?
-
People (social), Planet (environmental), and Profit/Prosperity (financial).
-
How does TBL differ from the traditional bottom line?
-
The traditional bottom line reports financial profit. TBL includes that plus social and environmental performance to reflect a company’s broader impact.
-
Who created the concept?
-
John Elkington, 1994.
-
Why is TBL important?
- It helps organizations account for their full costs and benefits to stakeholders and the environment, guiding decision‑making toward more sustainable, inclusive outcomes.
Bottom line
TBL reframes success as a balance of financial health, social responsibility, and environmental stewardship. Implementing it can strengthen long‑term resilience and stakeholder trust but requires careful measurement, transparent reporting, and thoughtful management of trade‑offs.
