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
People:
What is the impact on people?
Consider:
-
employees
-
customers
-
suppliers
-
communities
-
health and safety
-
accessibility
-
working conditions
-
social impact
Planet
Planet:
What is the environmental impact?
Consider:
-
emissions
-
energy
-
water
-
waste
-
biodiversity
-
natural resources
-
pollution
-
lifecycle impacts
Profit
Profit:
What is the economic impact?
Consider:
-
revenue
-
costs
-
margins
-
cash flow
-
investment
-
return
-
long-term value
The objective is not necessarily to maximizemaximise 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
- Examples include:
-
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
organizationsorganisations 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
organization'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
organization'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
organization'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
- Impact: How significant is the issue?
- Exposure:
How exposed is the
organisation?organization? - Relevance:
Does it affect this particular decision?
- Stakeholders:
Who is affected?
- Financial
ConnectionConnection:Could it affect revenues, costs, investment, risk, or value?
- Strategic
ConnectionConnection:Could it affect competitive advantage or long-term positioning?
Exposure
Relevance
Stakeholders
This helps prevent ESG analysis from becoming superficial.
Sustainability as Risk
Sustainability issues can create risk.
For example:
- Environmental
Risk
Risk: A company dependent on water may face supply constraints.
New environmental regulations may increase costs.
Poor labour practices among suppliers can create reputational and operational problems.
Customers may respond negatively to perceived irresponsible behavior.
Investors may become less willing to fund organizationsorganisations perceived as exposed to significant sustainability risks.
The key question becomes:
What could happen if the
organizationorganisation 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
and
Whatwhat opportunity exists if we act?
Connecting ESG to Financial Analysis
This is where your financial skills become particularly valuable.
Suppose an organizationorganisation 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:
ProblemProblem:
↓
What sustainability issue exists?
↓
Business ImpactImpact:
How does it affect the organization?
↓
Strategic OpportunityOpportunity:
What could the organizationorganisation do?
↓
Financial ImpactImpact:
What does it cost and what value does it create?
↓
Stakeholder ImpactImpact:
Who benefits or bears the cost?
↓
RiskRisk:
What could go wrong?
↓
RecommendationRecommendation:
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
- Financial: How much does the
organizationorganisation 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?
Environmental
Customer
Operations
Risk
Strategic
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 organizationorganisation 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
organizationorganisation 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:
Then:"For whom?"
- Then:
Then:"Compared with what?"
- Finally:
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
organizationalorganisational capabilities -
valued by customers
-
supported by the operating model
-
embedded into the
organization'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
- Immediate: What should happen first?
- Medium
TermTerm:What capabilities need to be developed?
- Long
TermTerm:How will the
organizationorganisation 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
- People: Who benefits?
Who might be harmed?
- Planet:
What environmental impact does it create?
- Profit:
What financial value does it create?
Planet
Profit
Then ask:
Does the recommendation still make sense when all three are considered?
If not, modify the recommendation.
Mad Skills Drill
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
Mistake
1 — - Treating ESG as a
Checklist
Checklist. Listing environmental, social, and governance issues without connecting them to the decision.
Mistake 2 —
A sustainability initiative still needs a credible business case when financial sustainability matters.
Mistake 3 —
Many sustainability initiatives can reduce costs or create new value.
Mistake 4 —
Real decisions rarely have zero downside.
Mistake 5 —
"More sustainable" means little without evidence.
Mistake 6 —
Sustainability should influence analysis when it is material, not simply appear on the final slide.
Mistake
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 recognizingrecognising 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.
OrganizationsOrganisations 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.
