Episode Title: Building a Sustainability Strategy Around Customers
Date: March 31, 2026
Host(s): Adi Ignatius & Alison Beard
Guest: Gautam Chaligala, Professor, IMD Business School and co-author of Clean: The Sustainability Strategy that Puts Customers First

Episode Overview

In this episode, Adi Ignatius and Alison Beard speak with Gautam Chaligala about how companies can rethink sustainability—not as a cost or constraint, but as a source of innovation and competitive advantage. Chaligala challenges commonly held beliefs around green consumers and offers a customer-centered framework for sustainability, focused on addressing inefficiencies and creating real value rather than simply meeting regulatory requirements or responding to political pressure.

Key Discussion Points & Insights

1. The Myth of the Green Consumer

[03:30 - 05:30]

• The Assumption: Most customers will pay a premium for sustainable products.
• Chaligala's Research: Less than 10% of customers are genuinely "green"—willing to pay more for sustainability.

  “Very few will. It's less than 10%. In all the research that we've done, green customers are willing to make that trade off. … Even in the US I've never heard a number greater than 10%.”
  — Chaligala [03:30]

• Why the Data Is Misleading:
  • People often give socially desirable answers.
  • Packaging changes or superficial tweaks can be mistaken for genuine intent.
  • Many buying decisions are made for other reasons (e.g., performance, image) and “green” is often a secondary, rationalized benefit.

2. Segmenting the Market: Green, Blue, and Gray Customers

[05:58 - 07:09]

• Green Customers: Willing to accept trade-offs for sustainability.
• Blue Customers: Buy sustainable only with incentives or when the cost is passed along.
• Gray Customers: Indifferent—sustainability is not on their radar.

  “Apple is a blue company because they pass on those price increases to consumers every September.”
  — Chaligala [06:40]

• Most research fails to distinguish these groups, leading to overestimating the market for sustainable goods.

3. The Weak Link Between Sustainability and Shareholder Value

[07:09 - 08:09]

• Meta-Analysis Result: A correlation of just 0.12 (statistically significant but not meaningful in business terms) between sustainability and profit/shareholder returns, signaling modest to negligible effects for most.

4. Green Fatigue and Reframing the Problem

[07:44 - 09:00]

• Consumer Fatigue: Overexposure and perceived greenwashing (e.g., 42% of EU sustainability claims contain some greenwashing) decrease consumer attentiveness.
• Problems Persist: Environmental challenges remain urgent, even if public focus wanes.

5. A Better Approach: Sustainability as a Source of Customer Value

[09:11 - 10:21]

• Wrong Question: “How do we become more sustainable?”
• Right Question: “How can we use sustainability as a catalyst to create more customer value?”

  “Instead of asking, how do we become the most sustainable company? We should say, how can we use sustainability as a catalyst to create more customer value? … ask not what you can do for sustainability, but what sustainability can do for your company.”
  — Chaligala [09:11]

6. Where Brand Purpose Falters: The Unilever Example

[10:21 - 13:43]

• Unilever’s Challenge: Overextension of purpose across 400+ brands led to incoherence and wasted marketing spend.
• The Mayonnaise Anecdote:

  “Any company that thinks they need to define a purpose for mayonnaise has in our view lost the plot.”
  — Quoting investor Terry Smith [12:36]

• Patagonia as an Exception:
  • Success due to a tight fit between mission and customer base, but still a niche player in the market.

7. Innovation, Not Messaging: The Finish Example

[14:22 - 17:23]

• True Sustainability as Innovation: Identify points of inefficiency or waste across the entire customer journey, not just in the product.
• Reckitt (Finish Detergent):
  • Discovered rinsing dishes wastes 20 gallons of water; innovated detergent to eliminate this step.
  • Added value by solving a universal pain point, not just appealing to green motivations.

  “You don’t need to be green, you don’t even need to be blue…you addressed it.”
  — Chaligala [16:41]

8. Scaling Sustainability: The Need to Target the Majority

[17:23 - 19:45]

• To scale, must serve blue and gray customers.
  • “Hope is not a strategy,” so aiming for everyone to “become green” is ineffective.
• Eye-for-eye vs. Eye-for-others Tradeoffs:
  • We accept personal cost for personal benefit (i.e., iPhone for higher quality), but sustainable purchases often require sacrificing for the public good or future generations—harder for most.

9. How to Foster Sustainability-Driven Innovation

[20:26 - 23:06]

• Map System-Wide Waste: Look for inefficiencies across the entire value chain.
• John Deere Example:
  • Used computer vision to decrease fertilizer waste—helped farmers and the environment, while justifying a price premium.
• Add a Customer Value Axis:
  • Evaluate projects not just by sustainability impact, but by customer value creation.

10. Culture: Avoid “Sustainability Mindset Overload”

[23:06 - 24:45]

• Constantly adding new “mindsets” (digital, agile, AI, sustainable) increases organizational friction and slows progress.

  “At the end you need one culture, a customer focused culture, a culture that is focused on adding customer value.”
  — Chaligala [24:18]

11. The Role of Chief Sustainability Officers

[24:45 - 25:52]

• Valuable for regulatory compliance and trend monitoring.
• Integrated models are emerging—sustainability under innovation or line-of-business heads, to ensure business/customer value focus.

12. Practical CEO Moves: Right to Play, Stay, and Win

[25:52 - 28:24]

• Right to Play: Compliance, regulatory minimum.
• Right to Stay: Resilience investments, like ensuring raw material supplies (e.g., coffee, cocoa).
• Right to Win: Optional, proactive moves to create customer value and differentiation.

  “First a CEO needs to have clarity on where is my money really going? Is too much going into just right to play and we are not doing enough in the others?”
  — Chaligala [27:41]

13. The Evolving Landscape: Flee, Freeze, Fight, Flourish

[28:24 - 30:59]

• Companies are divided:
  • Fleeing (often greenwashing), frozen, fighting, or flourishing.
• Long-term, innovation-focused companies will win, as environmental challenges—and opportunities for advantage—persist.

  “There is no dialing back for resilience reasons, for motivation reasons of our employees, and for actually innovation reasons. … Every time we have explained this logic and tied it to innovation… I have not once… faced resistance, not once.”
  — Chaligala [29:26]

14. Prediction: Who Will Win?

[30:59 - 32:49]

• Two Paths:
  • Compliance-oriented = survival
  • Innovation-oriented = sustainable advantage
• Digital Transformation Analogy:
  • Like post-dot-com-bust, those who commit and innovate flourish over time.

  “Sustainability problems are not going away. So companies that stay on this journey with this innovation lens will continue to thrive.”
  — Chaligala [32:19]

Notable Quotes & Memorable Moments

• “Ask not what you can do for sustainability, but what sustainability can do for your company.” — Chaligala riffing on JFK, [09:17]

• On Unilever and Purpose:

  • “If sustainability fits in naturally with the functional and emotional benefits… no problem, then it's a tight fit. But if it is, sitting on top of that can be a problem because you don't get very long to tell your message to consumers.” — Chaligala [11:48]

• On Tradeoffs:

  • “Many sustainability trade offs are I give up something for somebody else. Those are harder. When push comes to shove, I for I dominates I for somebody else.” — Chaligala [18:52]

• On Organizational Culture:

  • “At the end you need one culture, a customer focused culture, a culture that is focused on adding customer value.” — Chaligala [24:18]

• Focus sustainability strategy on creating clear customer value—identify inefficiencies, reduce waste, and connect efforts to direct benefits for all customer segments.
• Don’t bet on rapid shifts in consumer willingness to pay for “green.”
• Integrate sustainability with core business innovation, not as a standalone or purely regulatory function.
• Maintain a unified, customer-centric culture, not endless overlays of “mindsets.”
• Be realistic about the market: purpose-driven brands can win, but scale depends on serving the blue and gray customer masses.
• Prepare for the long haul: environmental imperatives aren’t going away, and companies leaning into innovation will seize the advantage.
