SEA Case Study: Interview with 3R Sustainability

The next SEA Study Cohort starts soon! Sign up to receive 12 one-hour study sessions and stay on track with your exam preparation.

Recently, we interviewed Gina MacIlwraith, MBA, SEP about the importance of continuous sustainability education and the value of the Sustainability Excellence credentials in the competitive consulting industry.


Gina is the Associate Director of Sustainability Assurance at
3R Sustainability, which is a women-owned business providing consulting services rooted in science, supported by data, and driven by innovation, education, and continual improvement. 3R delivers full-service sustainability solutions to their clients to achieve material business goals. Previously, Gina served as the General Manager of ISSP for almost four years, and she earned both her SEA and SEP credentials. Now she promotes study cohorts among her team at 3R, which has resulted in over 30 colleagues completing the SEA exam and over 75 colleagues completing the cohort training.

Why does 3R require the Sustainability Excellence credentials for your team? 



The reason we require the credentials is because it’s the best way to ensure our team members all have a consistent foundational understanding of ESG principles. Also, in consulting specifically, it is key to have a credential for third-party verification. You can earn other specific credentials, but this is the only one that demonstrates the foundations of a sustainability professional. So it gives us a step up as a consulting company to say that our entire team has a common understanding of the globally accepted fundamentals of sustainability. This is important right now, in particular as sustainability is both growing and becoming more and more controversial at times. Our staff understands the history and frameworks of sustainability – the why and where it came from, so we do more than just fill in the boxes in a report. 



Tell us more about the process for getting your team and interns credentialed. What does this look like for your team as far as resources and time? 


We’ve now done our study cohort six times. After last spring’s cohort with full-time employees, one team member commented that along with learning the fundamentals of our profession, employees were really able to bond and create interpersonal connections when studying together. It gives us a common language. 


For example, we bonded over John Elkington, and we were joking about getting John Elkington tattoos. Then, it seemed everybody had a John Elkington question on their [SEA] exam. We've got this group of employees who are hybrid or remote, and so we do sometimes have a hard time finding commonalities, but these cohorts give us something that's very work-related, but also very employee-engaging. 


And the truth is, when we do these cohorts, we very rarely study for it. The time is focused on interesting discussions about sustainability, what's going on in the world currently, and how this knowledge applies. So really, the SEA handbook is more than a study guide. It gives you an incredible framework for having conversations around sustainability. 



How do you fit the investment in credentialing into your overall business strategy?


Every employee at 3R gets 10 hours each month of continuing education professional development. This is at the core of our business because sustainability is changing so fast. We all need our 10 hours to keep up with everything. 


It’s also a commitment that Jana and I have made because it helps us better advise our clients. It just makes us better. Honestly, my tagline or my joking value proposition on business development calls is that I read the newsletters so you don’t have to. I sit through all those webinars, so you don’t have to. That’s how we help our clients, and the SEA is another piece of that. 



Do you have a specific example or a story that demonstrates how a staff member utilized the knowledge from their SEA or SEP to improve a client project?


When it comes to the SEP credential, we do it every day. That's our process. There's just two of us that have enough experience to qualify for the SEP, but the truth is that the SEP process is what we do with every one of our clients. We do materiality, we do stakeholder engagement, we create sustainability plans, and we do change management. 



For those starting out in the sustainability field, do you have any advice for them? 

Sustainability is an umbrella term; it’s rich in history. Understanding the full scope that can be included in the term is critical to success. The SEA credential gives practitioners the context to know how the field has evolved, along with the topics and issues that our profession can be tasked with as evidence of change.

February 20, 2026 As someone who works closely with sustainability practitioners and leaders, I constantly hear the same themes: “How do I get leadership to say yes?” “How do small businesses realistically do this?” “How do we scale change without burning out?” That’s exactly why I’m so excited about our upcoming webinar and working sessions. These aren’t theoretical discussions. They’re practical, interactive, and designed for those of us doing the hard work of driving sustainability forward — often without formal authority, large budgets, or perfect systems. Here’s what’s coming up and why I believe these sessions matter right now! Webinar: The advantages and challenges for small businesses in sustainability March 5, 12:00pm EST REGISTER HERE We often center sustainability discussions on large corporations. ESG frameworks. Reporting mandates. Multi-billion-dollar net-zero commitments but small businesses make up the majority of our economy. In our upcoming webinar, The Advantages and Challenges for Small Businesses in Sustainability , Colleen Spear brings clarity and practicality to this often overlooked audience. As the founder of Spearpoint Strategies in New England, Colleen works directly with small businesses across industries — from bottle manufacturing to law to clothing design. She helps organizations embed sustainability into operations and strategy through certification support, fractional management, and strategic planning. This session will explore: The barriers small enterprises face in sustainable business spaces Why most sustainability advice overlooks small business realities The natural strengths small businesses possess How to apply sustainability practically within constrained environments Small businesses often lack the complexity — and bureaucracy — of larger corporations. That agility can be a major advantage. Decision-makers are accessible. Values can be integrated quickly. Cultural shifts can happen faster. Rather than positioning small businesses as behind, this session reframes them as powerful drivers of innovative, community-centered solutions. If you work with small enterprises, advise them, or operate one yourself, this webinar will provide actionable insights and language you can apply immediately. Webinar: Influencing Up: Strategies for Sustainability Leaders April 28, 5:00pm EST REGISTER HERE Our upcoming session with Dr. André Taylor, Strategies for ‘Influencing Up’ as a Sustainability Leaders , focuses on one of the most critical — and underdeveloped — skills in sustainability work: influencing without authority. Dr. Taylor brings a powerful combination of experience. He began his career as an environmental manager and scientist before earning a mid-career PhD in leadership at Monash University. Today, he serves as Leadership Specialist and Adjunct Associate Professor at the International WaterCentre and works extensively with sustainability and executive leaders. Why does this matter? Because sustainability practitioners rarely have direct authority over finance teams, executives, procurement departments, or policymakers. Yet we are expected to influence all of them. This session will explore: How to gain buy-in from senior leaders How to navigate functional silos How to influence across sectoral boundaries How to build authority when you don’t have the title What I appreciate most about this session is that it reframes influence as a skill — not a personality trait. We’ll dive into practical tools and concepts that help sustainability leaders: Speak the language of decision-makers Align initiatives with strategic priorities Understand motivations and incentives Work effectively across power dynamics If you’ve ever felt stuck waiting for approval, resources, or executive sponsorship, this webinar is designed for you. Implementing the AIMS Framework: From Momentum to Scale Four Interactive Working Sessions: March 18th (12pm EST) | Amplify REGISTER HERE April 22nd (12pm EST) | Influence REGISTER HERE May 12th (12pm EST) | Multiply REGISTER HERE June 25th (12pm EST) | Scale REGISTER HERE For those ready to go deeper, we’re offering a four-part interactive working series led by Dr. Jacqueline Kerr. Dr. Kerr has been published in Harvard Business Review and is in the top 1% of cited social scientists worldwide. Her work blends behavior change, implementation science, and systems thinking to help sustainability leaders deliver results — even in resource-constrained settings. These sessions aren’t passive webinars. They’re Miro-based, hands-on working sessions built around real initiatives participants are leading. Here’s how the journey unfolds: AMPLIFY — Recognizing Hidden Success We begin by mapping sustainability wins — even small ones — and identifying their ripple effects. Participants will: Surface hidden ROI Identify informal impact makers Recognize patterns across companies Publicly commit to amplifying a success story Key insight: change is already happening — it’s just often invisible. INFLUENCE — Removing Barriers Without Authority We diagnose stalled initiatives using an Action Audit framework. Together, we map barriers across: Strategy & Design People & Engagement Systems & Structures Feedback & Adaptation Participants will leave with: Clear barrier diagnoses Peer-tested influence strategies Commitment to remove one key blocker The big realization here? Most stalled initiatives are people challenges embedded within unsupportive systems. MULTIPLY — Creating Action Hubs We explore what makes groups succeed versus stall and design collaborative “action hubs” around shared problems. Participants will: Identify high-impact problems worth solving together Map who needs to be involved Develop invitation language Learn facilitation tactics that build ownership When groups co-design solutions, momentum becomes self-sustaining. SCALE — Building Systems That Spread Change Finally, we design pathways for scaling impact beyond individual teams. We’ll: Map where wins can spread Identify facilitator pipelines Explore how peer networks enable growth Commit to developing new leaders The insight here is transformative: when you train facilitators and activate system levers, change no longer depends on one sustainability champion pushing relentlessly. Why These Sessions Matter Now Across sectors, sustainability professionals are navigating political tension, budget constraints, competing priorities, and burnout. What excites me about this lineup of upcoming webinars and working sessions is that they address the real work: Influence without authority Practical sustainability in small enterprises Behavior change and implementation Scaling change through systems, not heroics These experiences are designed not just to inform — but to equip. Whether you're looking to sharpen your executive influence, support small business transformation, or move from isolated wins to systemic impact, there’s a session built for you. And perhaps most importantly, these sessions create community. You won’t just learn frameworks — you’ll see patterns across organizations, borrow strategies from peers, and build networks that last beyond a single meeting. If you’re serious about driving sustainable change in 2026, I invite you to join us. We’re not just talking about sustainability. We’re building the leadership capacity to deliver it.

January 16, 2026 At the International Society of Sustainability Professionals (ISSP), strategy is not theoretical. It is practical, action-oriented, and grounded in the real needs of sustainability professionals working in complex and rapidly evolving environments. The ISSP 2026 Strategic Plan is a one-year, execution-focused roadmap designed to strengthen ISSP’s role as a global professional association for sustainability practitioners. Built directly from member feedback gathered through Town Halls, surveys, and ongoing conversations, the plan focuses on three strategic priorities: financial stability, relevant professional knowledge, and meaningful member engagement. This article explains what the 2026 Strategic Plan is, why these priorities matter, and how member input directly shaped ISSP’s direction. What the ISSP 2026 Strategic Plan Is—and Is Not The 2026 Strategic Plan is not a long-term vision statement or a five-year forecast. It is a focused, one-year plan designed to deliver measurable progress. The plan is intended to: Strengthen ISSP’s financial sustainability Modernize sustainability education and credential resources Improve the member experience across career stages Each priority includes defined actions, timelines, and success metrics, ensuring accountability and transparency.

Elizabeth Dinschel, MA, MBA, is the Executive Director of ISSP Earlier this month, we hosted our first global ISSP Town Hall since I stepped into the role of Executive Director. I logged off that call energized, humbled, and deeply grateful for the honesty, generosity, and care that our members brought into the space. This Town Hall was never meant to be a one-way update. It was designed as a listening session — a chance for ISSP leadership and staff to hear directly from sustainability professionals across regions, sectors, and career stages. And you delivered. What follows are a few reflections on what I heard, what we learned, and where we’re headed next together. Why We Called This Town Hall ISSP has gone through a period of transition — new leadership, new staff, and a renewed focus on modernizing how we serve a truly global membership. Change can be energizing, but it can also create moments of uncertainty and disconnection. We knew we needed to pause, gather our community, and listen with intention. The Town Hall brought together members from multiple continents, industries, and disciplines. Sustainability practitioners, consultants, engineers, communicators, policy professionals, and career-transitioners all showed up with thoughtful questions and candid feedback. One thing was immediately clear: this community cares deeply about its work, about each other, and about ISSP’s role in supporting sustainability professionals at a challenging moment for the field.
