A guide to validation for sustainability professionals


A guide to validation for sustainability professionals.


At its core, sustainability work is about change. We aim to transform systems, shift mindsets, and alter behaviours across organisations and society.

Yet despite our compelling data and urgent calls to action, we often encounter resistance that seems illogical or frustrating.

After two decades in this field, I have learned that our effectiveness is not just about having the right information. It is about how we connect with others.

Caroline Fleck's work on validation offers powerful insights for sustainability professionals facing this challenge.

While her concepts were originally developed in psychological contexts, they provide a framework that can improve our ability to influence and create meaningful change in the sustainability space.

Understanding Validation in Sustainability Contexts

Validation, as Fleck describes it, is the practice of acknowledging and accepting another person's experience without judgment.

In sustainability work, this means creating space for stakeholders to express their concerns, reservations, and perspectives, even when they differ from our own, before diving into solutions or counterarguments.

This approach runs counter to how many of us operate. When faced with resistance to sustainability initiatives, our instinct is often to present more data, emphasise urgency, or highlight the business case.

These tactics, while logical, frequently fail because they do not address the underlying emotional and psychological barriers to change.

Why Validation Matters in Sustainability

Sustainability professionals face unique challenges that make validation particularly valuable.

We often deliver difficult messages that threaten the status quo, challenge existing business models, or require significant investment.

Stakeholders may experience fear, defensiveness, or cognitive dissonance in response.

When we validate these responses rather than dismissing them, we accomplish several critical objectives:

First, we build trust. When stakeholders feel understood rather than judged, they are more likely to engage constructively. This trust becomes essential capital when asking for difficult changes.

Second, we gain deeper insights. Validation involves genuine curiosity about others' perspectives, which often reveals underlying concerns or motivations that would not otherwise surface. These insights can help us tailor more effective approaches.

Third, we model the inclusive thinking that sustainability requires. The complex challenges of sustainability demand diverse perspectives and collaborative problem-solving. Validation demonstrates our commitment to this approach.

Fourth, we reduce defensive reactions. When people feel their concerns are dismissed, they typically double down on resistance. Validation disrupts this pattern, creating openings for new thinking.

The Validation Framework for Sustainability Professionals

Drawing from Fleck's work, here's how sustainability professionals can apply validation in their work:

Active listening comes first. Before presenting solutions or correcting misconceptions, take time to understand stakeholders' perspectives fully. This means asking open-ended questions, paraphrasing to confirm understanding, and resisting the urge to immediately counter with facts.

Acknowledge the validity of concerns. Even when stakeholders' perspectives seem misguided, recognise that their concerns make sense given their priorities and information. This does not mean agreeing with incorrect information, it means acknowledging the legitimacy of their reaction based on their understanding.

Validate emotions, not just logic. Sustainability challenges often evoke strong emotions such as anxiety about change, guilt about past practices, or fear about the future. Creating space for these emotions rather than focusing exclusively on rational arguments can transform the conversation.

Look for legitimate core concerns. Even in positions that seem entirely opposed to sustainability objectives, there are usually legitimate underlying concerns that can be validated. Identifying these creates common ground from which to work.

Connect validation to values alignment. After validation, look for ways to connect sustainability objectives to stakeholders' existing values and priorities rather than asking them to adopt entirely new frameworks.

Common Pitfalls to Avoid

Effective validation requires avoiding several common traps:

Validation is not agreement. Many sustainability professionals worry that validating concerns means endorsing incorrect information or delaying urgent action. In reality, validation creates the psychological safety necessary for stakeholders to reconsider their positions. It is a means to more effective influence.

Avoid false validation. Statements that begin with validation but quickly pivot to correction ("I understand your concern, but you're wrong about...") typically backfire. True validation requires staying in the space of understanding before moving to solution-finding.

Don't rush the process. The urgency of sustainability challenges can make us impatient with the validation process. However, investing time upfront in validation typically leads to faster implementation later by reducing resistance and building commitment.

Beware of confirmation bias. We tend to validate perspectives that align with our own more readily than those that challenge us. Be particularly conscious about validating stakeholders whose viewpoints differ significantly from ours.

The Path Forward

Incorporating validation into our sustainability practice does not require abandoning our commitment to data, science, or urgency.

Instead, it enhances our effectiveness by recognising that human psychology plays as crucial a role in change as factual information does.

As sustainability professionals, we often position ourselves as technical experts.

Fleck's validation framework suggests we must also become experts in human connection, creating psychological safety that allows for transformation rather than defensiveness.

How we talk about sustainability matters as much as what we say.

By incorporating validation into these conversations, we can transform resistance into collaboration and accelerate the changes our world so urgently needs.

The most successful sustainability professionals I have observed throughout my career are not just those with the strongest technical knowledge.

They are those who excel at bringing others along on the journey.

What sustainability professionals can learn from Pixar’s storytelling. The work of sustainability professionals, whether it is driving decarbonisation, advocating for circular economies, or promoting social equity, is at its core about a story. Yet too often, we lead with data, not emotion. We talk about metrics, not meaning. We focus on systems, not the people they serve. The result? Our messages fall flat, failing to inspire the action we so desperately need. What if we approached...

Training the next generation of Scope 3 emissions managers. Managing Scope 3 emissions is one of the most challenging aspects of corporate sustainability. These indirect emissions, occurring across complex value chains, typically account for more than 70% of an organisation's carbon footprint. Yet many sustainability professionals struggle to effectively measure and reduce them. This article outlines a systematic approach to building Scope 3 management capabilities, and offers a training...
