Sustainability and ESG

Chapter 1: Sustainability and ESG - Beyond Profit: Understanding the Triple Bottom Line

"A sustainable strategy isn't one that sacrifices profit. It's one that understands how profit, people, and the planet are connected."

identify opportunities and risks created by sustainability challenges
evaluate sustainability initiatives strategically rather than cosmetically
incorporate sustainability into recommendations
avoid treating ESG as simply a checklist
recognise the difference between meaningful sustainability and greenwashing

Why This Matters

Sustainability is increasingly part of strategic decision-making. Organisations face questions about:

climate and environmental impact
energy use
waste
emissions
resource scarcity
employee well-being
diversity and inclusion
community relationships
supply-chain practices
governance
reputation
regulatory expectations
long-term resilience

These issues can affect the organisation's ability to create value. They can influence:

costs
revenues
access to capital
customer demand
employee attraction and retention
regulatory risk
operational resilience
reputation
competitive advantage

This means sustainability should not simply appear in the final slide under a heading called "ESG Considerations." It should influence the analysis when it is material to the decision.

What Is Sustainability?

At its simplest, sustainability asks: Can the organisation create value today without undermining its ability to create value tomorrow? This introduces a time dimension into decision-making.

A decision that creates $10 million of profit this year may look attractive. But what if it:

creates significant environmental liabilities?
damages the organisation's reputation?
increases regulatory exposure?
causes employees to leave?
depletes a critical resource?
creates an unsustainable cost structure?

The short-term financial result may not tell the whole story.

The Triple Bottom Line

A useful way to think about sustainability is through the Triple Bottom Line.

People: What is the impact on people? Consider:

employees
customers
suppliers
communities
health and safety
accessibility
working conditions
social impact

Planet: What is the environmental impact? Consider:

emissions
energy
water
waste
biodiversity
natural resources
pollution
lifecycle impacts

Profit: What is the economic impact? Consider:

revenue
costs
margins
cash flow
investment
return
long-term value

The objective is not necessarily to maximise one dimension independently. It is to understand the relationship between them.

The Three Dimensions Are Connected

A common mistake is to think:

People + Planet = Cost
Profit = Benefit

That is often too simplistic. Consider employee turnover. Improving working conditions may increase costs in the short term. But it could also:

reduce turnover
increase productivity
improve recruitment
strengthen customer service
reduce training costs

Similarly, reducing energy consumption may require an upfront investment. But it could:

reduce operating costs
reduce exposure to energy-price volatility
lower emissions
improve resilience

The important question is: What is the relationship between the sustainability initiative and business value?

ESG: Environmental, Social, and Governance

ESG provides another lens.

Environmental - Examples include:

emissions
energy use
waste
water
pollution
climate risk
resource use

employees
health and safety
diversity
human rights
customers
communities
supply-chain practices

Governance - Examples include:

board oversight
executive accountability
transparency
ethics
risk management
executive compensation
shareholder rights

ESG can therefore help identify risks and opportunities that may not appear in a traditional financial analysis.

Sustainability Is Not the Same as ESG

It is useful to distinguish the concepts.

Sustainability is the broader idea of creating value over the long term while considering economic, social, and environmental consequences.
ESG provides a set of categories through which organisations can evaluate and communicate environmental, social, and governance factors.

In a case competition, the terminology matters less than the thinking. The question is: What non-financial factors could materially affect the organisation's ability to create and sustain value?

Discover Your Mad Skills Principle

Don't add ESG to the analysis because you think judges expect it. Identify ESG issues because they matter to the decision.

This is an important distinction. A weak team may write: "We recommend implementing solar panels because sustainability is important." A stronger team asks: "How does the organisation's energy exposure affect its costs, resilience, regulatory risk, reputation, and long-term competitiveness?" Now sustainability becomes strategic.

Materiality

Not every ESG issue matters equally. A case may mention:

climate change
employee diversity
packaging
water usage
governance
community relations

But that doesn't mean every issue belongs in your recommendation. The key concept is materiality. Ask: Could this issue materially affect the organisation's decision, performance, stakeholders, or long-term value? If yes, investigate it. If no, don't force it into the analysis.

The Materiality Test

For each potential sustainability issue, ask:

Impact: How significant is the issue?
Exposure: How exposed is the organisation?
Relevance: Does it affect this particular decision?
Stakeholders: Who is affected?
Financial Connection: Could it affect revenues, costs, investment, risk, or value?
Strategic Connection: Could it affect competitive advantage or long-term positioning?

This helps prevent ESG analysis from becoming superficial.

Sustainability as Risk

Sustainability issues can create risk. For example:

Environmental Risk: A company dependent on water may face supply constraints.
Regulatory Risk: New environmental regulations may increase costs.
Supply-Chain Risk: Poor labour practices among suppliers can create reputational and operational problems.
Reputation Risk: Customers may respond negatively to perceived irresponsible behaviour.
Capital Risk: Investors may become less willing to fund organisations perceived as exposed to significant sustainability risks.

The key question becomes: What could happen if the organisation doesn't address this issue?

Sustainability as Opportunity

Sustainability isn't only about avoiding problems. It can also create opportunities. Examples include:

new products
new customer segments
lower operating costs
improved resource efficiency
stronger employee engagement
new partnerships
access to new markets
competitive differentiation
improved resilience

The strongest case analyses examine both sides. What is the risk of doing nothing? And what opportunity exists if we act?

Connecting ESG to Financial Analysis

This is where your financial skills become particularly valuable. Suppose an organisation is considering a $5M energy-efficiency investment. Don't stop at: "It reduces emissions." Ask:

What is the initial investment?
What operating costs decline?
What is the annual savings?
What is the payback?
What is the NPV?
What assumptions drive the result?
What happens if energy prices decline?
What happens if energy prices increase?
What is the expected useful life?
What regulatory changes could affect the economics?

Now the sustainability initiative has become a business decision.

The Sustainability Business Case

A useful structure is:

Problem: What sustainability issue exists? --> Business Impact: How does it affect the organisation? --> Strategic Opportunity: What could the organisation do? --> Financial Impact: What does it cost and what value does it create? --> Stakeholder Impact: Who benefits or bears the cost? --> Risk: What could go wrong? --> Recommendation: What should management do?

This is essentially the same case-solving process you have already learned. The lens has changed.

Example: Reducing Packaging

Imagine a company spends $10M annually on packaging. It is considering a $2M investment to redesign its packaging.

The proposal would:

reduce material use by 20%
reduce waste
lower transportation costs
improve environmental performance

A weak analysis says: "This is good for the environment." A stronger analysis asks:

Financial: How much does the organisation save?
Environmental: How much waste is eliminated?
Customer: How might customers respond?
Operations: Does the new packaging affect transportation or production?
Risk: Does the new material affect product quality?
Strategic: Could the company differentiate itself?

Now the recommendation is based on a broader understanding of value.

Greenwashing

One of the dangers in sustainability analysis is greenwashing. Greenwashing occurs when an organisation presents itself as environmentally responsible without meaningful evidence or impact. In case competitions, teams can accidentally do something similar. For example: "Our recommendation will improve sustainability."

But how?
By how much?
Over what period?
At what cost?
Compared with what alternative?

Without evidence, the statement is largely meaningless.

Avoid the "Green Sticker"

A common case-solving mistake is to take an existing recommendation and add an environmental benefit at the end. For example: "We recommend expanding internationally because it will increase revenue. It will also demonstrate our commitment to sustainability." That isn't necessarily meaningful sustainability analysis. Instead, sustainability should influence the decision itself. Perhaps: "We recommend entering Region A rather than Region B because it offers comparable growth potential with significantly lower supply-chain emissions and stronger regulatory alignment." Now sustainability affects the choice.

Sustainability Trade-Offs

Real sustainability decisions often involve trade-offs. A solution may:

reduce emissions but increase costs
improve employee wages but reduce margins
increase accessibility but require investment
improve environmental performance but increase production complexity

Don't hide the trade-off. Make it explicit. For example: "The initiative increases annual operating costs by $1.2M but reduces emissions by 30% and reduces regulatory exposure. We recommend proceeding because the organisation has sufficient financial capacity and the regulatory risk is expected to increase." That is a business argument.

Coach's Lens

When a team says: "This is the more sustainable option."

Ask: "Sustainable in what way?"
Then: "For whom?"
Then: "Compared with what?"
Finally: "At what cost?"

These questions force the team to move beyond vague sustainability language.

A Sustainability Scorecard

For more complex cases, consider creating a simple scorecard.

Dimension	Option A	Option B	Option C
Financial Value	High	Medium	Low
Environmental Impact	Medium	High	Low
Social Impact	Low	High	Medium
Strategic Fit	High	High	Medium
Risk	Medium	Low	High
Long-Term Resilience	Medium	High	Low

The purpose isn't to create artificial precision. It is to make the trade-offs visible.

Sustainability and Competitive Advantage

Sustainability can become a source of competitive advantage when it is:

difficult to replicate
aligned with organisational capabilities
valued by customers
supported by the operating model
embedded into the organisation's strategy

For example, simply announcing a sustainability goal is unlikely to create lasting competitive advantage. But redesigning the entire supply chain around lower-cost, lower-impact operations may. This is where sustainability connects back to strategic analysis.

Sustainability and Implementation

A sustainability recommendation should also have an implementation plan. Consider:

Immediate: What should happen first?
Medium Term: What capabilities need to be developed?
Long Term: How will the organisation measure and sustain progress?

Potential metrics could include:

emissions
waste
energy use
employee retention
safety incidents
customer access
community impact
cost savings
return on investment

The same principle applies: If you can't measure whether the recommendation is working, it is difficult to manage it.

Mad Skills Drill

The Triple Bottom Line Test

Take an existing recommendation. Evaluate it from three perspectives.

People: Who benefits? Who might be harmed?
Planet: What environmental impact does it create?
Profit: What financial value does it create?

Then ask: Does the recommendation still make sense when all three are considered? If not, modify the recommendation.

The ESG Attack

Choose a case recommendation and ask:

What is the environmental risk?
What is the social risk?
What is the governance risk?

Then ask:

Which of these is actually material?

The final question is important. The goal is not to find an ESG issue. The goal is to identify the ESG issue that matters.

Common Mistakes

Treating ESG as a Checklist. Listing environmental, social, and governance issues without connecting them to the decision.
Ignoring Financial Reality. A sustainability initiative still needs a credible business case when financial sustainability matters.
Assuming Sustainability Always Costs More. Many sustainability initiatives can reduce costs or create new value.
Ignoring Trade-Offs. Real decisions rarely have zero downside.
Using Vague Language. "More sustainable" means little without evidence.
Adding ESG at the End. Sustainability should influence analysis when it is material, not simply appear on the final slide.
Greenwashing. Making sustainability claims without measurable evidence.

Chapter Summary

Sustainability changes the questions we ask in a case. Instead of asking only: "Will this make money?" we may also need to ask:

"What impact will this decision have?"
"Who is affected?"
"What risks are we creating?"
"What value are we creating over the long term?"

The Triple Bottom Line provides a useful starting point:

People
Planet
Profit

ESG provides another useful lens:

But neither should become a checklist. The real skill is recognising when these factors are material to the decision and integrating them into the analysis.

Key Takeaways

✓ Sustainability is about long-term value creation.

✓ The Triple Bottom Line considers People, Planet, and Profit.

✓ ESG considers Environmental, Social, and Governance factors.

✓ Not every ESG issue is material to every case.

✓ Sustainability can create both risks and opportunities.

✓ Connect sustainability issues to strategy and financial performance.

✓ Make trade-offs explicit.

✓ Avoid vague sustainability claims.

✓ Don't add ESG after the recommendation—integrate it when it matters.

✓ Measure the impact of sustainability initiatives.

✓ Strong sustainability recommendations remain strategically and financially credible.

The goal isn't to make every decision "green." The goal is to make decisions that recognize the full consequences of creating value.

Looking Ahead

Sustainability is only one dimension of the broader decision environment. Organisations don't operate in isolation. They operate within networks of customers, employees, suppliers, investors, governments, communities, and other stakeholders. The next chapter expands the lens from People, Planet, and Profit to the question: Who has a stake in this decision—and how should their interests influence what we recommend? That is the challenge of Stakeholder Capitalism.
