ISSB's Impacts on Sustainability Officers

Robert G. Eccles, PhD

The ISSB can make Chief Sustainability Officers more relevant or less relevant. They Have to Choose.


My friend Bhakti Mirchandani has written about the historical significance of the creation of the International Sustainability Standards Board (ISSB). She is absolutely right about this. Sustainability is going mainstream in the corporate and investment communities, and the ISSB will help to further accelerate this. It will give us the same high-quality standards for measuring and reporting on sustainability performance that we have for financial performance. Along with this will go much higher-quality internal control and measurement systems and, ultimately, the same degree of internal and external audit rigor that goes into the financial statements. Finally, financial and sustainability reporting will be on par in terms of quality and relevance. This will enable true integrated reporting. Companies and investors will be able to rigorously understand how sustainability performance and financial performance contribute to each other. There are still those locked into an ideology that sustainability = philanthropy, despite the growing body of empirical evidence that a focus on a company's material ESG issues contributes to financial performance.


All good news, right? Ironically, maybe not for Chief Sustainability Officers (CSOs), by whatever name, who fail to appreciate how much the ISSB is going to change their lives. Ironically, the ISSB could make the role of CSO less relevant. And, let’s be honest, while most companies proclaim their deep commitment to sustainability, the role of the CSO is often a marginal one when it comes to resources, seat at the executive table, and influence on strategic and capital allocation decisions. The ISSB could make the situation worse. Or it could make it much better. It all depends on how a CSO decides to handle this, and his or her relationship with the CFO.



I will explain this more, but first let me put this in some historical perspective. I think it’s fair to say that I am one of the earliest enthusiasts for an International Sustainability Standards Board (ISSB), going back 30 years. I started working in the domain of sustainability reporting, without knowing it by name 30 years ago. Long before it was fashionable. It was a marginal, erratic, fringe activity until the Global Reporting Initiative (GRI) came along in 1997 and started to put intellectual credibility and structure to the concept.


More acronyms came along, and subsequent years have seen the formation of CDP (2000), the Climate Disclosure Standards Board (CDSB-2007), the International Integrated Reporting Council (IIRC-2010; I was one of the founders), the Sustainability Accounting Standards Board (SASB-2011; I was the Founding Chairman), and the Task Force on Climate-related Financial Disclosures (TCFD-2015). The IFRS Foundation, much to my happy surprise, issued its consultation for the ISSB in September of 2020, just two years after my Oxford colleague Richard Barker and I published our Green Paper “Should FASB and IASB be responsible for setting standards for nonfinancial information?” This paper was the basis of a heated debate at the Oxford Union. While the “Ayes” supporting mandated corporate sustainability reporting carried the day about two-to-one, it was far from a unanimous vote.


During these past three decades, we had two conversations going on. One was between the CEO, CFO, and Head of Investor Relations with shareholders. These conversations were all about financial performance and financial materiality defined in a narrow sense. The other was between the CSO and the company’s stakeholders, where materiality was defined in broader terms that typically included both “single materiality” (what matters to investors) and “double materiality” (what matters to stakeholders in terms of making the world a better or worse place). While this distinction is still relevant, and the ISSB is focused on single materiality, the line is a blurry one and can change quickly through dynamic materiality.


Over a very short period of time, the IIRC and SASB merged to form the Value Reporting Foundation, which is being consolidated into the ISSB. It was recently announced that the same will happen with CDSB, and the TCFD framework will also inform the work of the ISSB. A Chair (Emmanuel Faber), Vice Chair (Sue Lloyd), and Special Advisor to the Chair (Janine Guillot) have been named. Soon the ISSB will issue its exposure drafts for climate and sustainability reporting in general. Sustainability reporting will move from the land of NGOs and done so on a voluntary basis to the land of securities regulators and done on a mandated basis.


Investors are eager for this to happen, because they will finally have the high quality and comparable information they need on a company’s sustainability performance. And who will they talk to about this? The same people they’ve been talking to before — the CEO, CFO, and Head of IR. Of course, this will raise challenges for those used to talking to investors. They will have to learn to talk sustainability performance and show its relevance to financial performance. This will not be easy. Sustainability is a complex domain covering a broad range of environmental and social issues, and it doesn’t have (yet) anything like the underlying framework of double-entry bookkeeping. But this can be learned. And these people have the advantage of already having credibility with the investment community. They also have a big incentive to become bilingual. The portfolio managers who make the buy and sell decisions are learning how to integrate material sustainability factors into their investment decisions.


I can envision the ironic scenario where the CSO becomes more fringe as sustainability continues its move into the mainstream of corporate and investor decisions. The way things stand now in most companies, the CSO will not be part of the conversation. Sure, he or she will continue to engage with stakeholders and report on double materiality issues, but the center of gravity of the sustainability conversation will shift to the increasingly bilingual finance folks.


It doesn’t have to be that way. So, what is a CSO to do? The answer is a simple one. Learn to talk financial performance and show how it is related to sustainability performance. It’s no harder to learn finance than sustainability. It’s probably easier. Think hard about the cause-and-effect relationships between different factors of sustainability performance and different factors of financial performance. Think hard about the relevant time frames. Think hard about how to work with the CFO to implement integrated thinking in the company so that integrated reporting contributes to internal decision making, rather than being the after-the-fact ornament it is in most cases.


One last thought. There has been an ongoing debate about who the CSO should report to. Obviously, there’s no single right answer to this. I do think there are wrong answers, like marketing, PR, and public policy. Sure, it’s always good to report to the CEO. Everyone wants to.


But my vote is for the CSO to report to the CFO. There are two good reasons for doing so. The first is that it will facilitate mutual bilingual learning. The second is that CFOs know all about standards and the rigorous internal control and measurement systems for implementing these standards and reporting on them. Sustainability reporting needs a big upgrade here, and the ISSB will make this possible.


CSOs are at a juncture. They can stay in the world they’re comfortable with. They’ll still be respected, but their voice will be less. Or they can stretch themselves and become more of the conversation with the stakeholder called shareholders. The choice is theirs.

Paper cut-out figures holding hands in a chain against a dark blue background.

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.
Can sustainability be saved by tackling loneliness, not just CO₂ emissions?

Raz Godelnik is an Associate Professor of Strategic Design and Management at Parsons School of Design — The New School. He is the author of Rethinking Corporate Sustainability in the Era of Climate Crisis . You can follow him on LinkedIn .  Can sustainability be saved by tackling loneliness, not just CO₂ emissions? Earlier this month, I stopped at Sunshine Coffee in Laramie, Wyoming, on our way to Yellowstone Park. What brought me there was the fact that it’s a zero-waste coffee shop, with no single-use consumer items. In other words, there are no disposable cups — not for customers dining in, and not even for those who want their coffee to go, like I did. Instead, you can either bring your own reusable cup or get your drink in a glass jar for $1, which is refunded on your next order when you return it (or you can simply keep it, as I did). At first, I was excited about the zero-waste coffee shop concept, wondering what it would take for Starbucks and other coffee chains to adopt it and eliminate the waste that has become an integral part of our coffee (and other drinks) consumption. But as I waited for my coffee, I began to notice something else — something that had little to do with waste and everything to do with people. As I looked around, I noticed their stickers. Beneath the logo, it read: Zero waste. Community space . Suddenly it clicked — this coffee shop isn’t just about eliminating waste; it’s about creating a place where people feel connected. As owner and founder of Sunshine Coffee, Megan Johnson, explained in an interview with This is Laramie : “I wanted to bring sustainable values to Wyoming as well as build a business that serves the community.” That got me thinking about how the second part — serving the community — is integral to the first. After all, in a world where loneliness — a key barrier to people’s well-being — is on the rise, shouldn’t creating spaces for connection be just as central to sustainability as going zero waste?

Nicole Cacal, MSc, is Executive Director of the TRUE Initiative in Hawaii and serves as Vice President on the Governing Board of ISSP. In our October blog, she challenges the prevailing narrative around AI's environmental impact, arguing that strategic deployment can transform AI from an environmental burden into a driver of recursive sustainability. Drawing on her background in strategic design and technology management, she presents emerging pathways for responsible AI adoption that balance societal benefit against environmental risk. Toward Appropriate and Responsible AI: Pathways to Sustainable Adoption and Infrastructure Nicole Cacal · October 27, 2025 Whenever I give an AI presentation or offer advice on AI adoption, whether to business owners, C-level executives, or sustainability professionals, one concern surfaces time and time again, especially here in Hawaii: the environmental tension. People want to explore AI's potential, but they're acutely aware of the energy consumption, the water usage, the carbon footprint. It's become almost a reflex: mention AI, and someone immediately raises the environmental cost. I get it. The data centers, the training runs, and the resource demands. They're real and they're significant. But here's what I've come to believe: if we shift the narrative from focusing solely on AI's detriment to the environment and instead ask how much good it can create, what role we can play in driving data centers to go greener, and how we can generate recursive sustainability, we unlock better questions. We start thinking forward rather than just defensively. As sustainability professionals, our job isn't to reject technology wholesale. It's to shape its evolution. And right now, we have an opportunity to influence how AI develops and deploys in ways that align with planetary boundaries and social equity. But to do that, we need to move beyond binary thinking. Right-Sizing AI: Why Bigger Isn't Always Better One of the most overlooked levers we have for sustainable AI is also one of the simplest: choosing the right model for the job. The AI industry has been caught in a "bigger is better" arms race for years now. Every new model release touts more parameters, more capabilities, more everything. And sure, these massive general-purpose models are impressive. But they've created a dangerous assumption: that every task requires maximum firepower. This is where my strategic design training from Parsons kicks in. Good design isn't about having the biggest toolkit. It's about matching the tool to the task. It's about elegance through constraint. The same principle applies to AI deployment. The emerging concept of "Small is Sufficient " is gaining traction for good reason. Research shows that selecting smaller, purpose-fit AI models for specific tasks can achieve nearly the same accuracy as their larger counterparts while reducing global energy demand by up to 28% . Twenty-eight percent. That's not marginal; that's transformational. Think about what your organization actually needs. Are you processing customer service inquiries? Analyzing spreadsheet data? Generating product descriptions? Most of these tasks don't require a frontier model. A fine-tuned, task-specific model will do the job with a fraction of the computational overhead. The shift we need is cultural as much as technical. We need to move from asking "what's the most powerful AI we can deploy?" to "what's the most appropriate AI for this specific use case?" That question changes everything, from procurement decisions to vendor relationships, internal training, and infrastructure planning. AI as Infrastructure Manager: The Self-Optimizing Data Center Here's an irony that doesn't get enough attention: AI might be energy-intensive, but it's also one of our best tools for managing energy systems efficiently. When we only think of AI as a consumer of data center resources, we miss part of the story. AI can also be the conductor of efficiency, orchestrating complex systems in real-time to minimize waste and maximize renewable integration. Consider three optimization domains where AI is already making measurable impact: Cooling systems: Data centers generate enormous heat, and cooling accounts for a massive portion of their energy use. AI can continuously adjust cooling based on workload patterns, outside temperature, humidity, and dozens of other variables, optimizing in ways that static systems simply can't match. Workload scheduling: Not all computing tasks need to happen immediately. AI can intelligently schedule batch processing, model training, and background tasks for times when renewable energy is abundant or when grid demand is lowest. This isn't just theory. Companies are already doing this. Renewable energy integration: This one hits close to home in Hawaii, where we're working toward aggressive renewable energy targets but face unique challenges with grid stability and storage. AI-managed facilities can modulate demand in response to solar and wind availability, essentially turning data centers into flexible grid assets rather than inflexible burdens. When organizations approach their operations as integrated systems rather than collections of independent components, they achieve results that surprise even them. AI-orchestrated data centers represent this systems thinking at its most sophisticated. The technology optimizes itself recursively, reducing the footprint of AI through AI. That's the kind of elegant solution we should be scaling. Measuring What Matters: Beyond Energy to Net Benefit But here's the challenge: if we only measure AI's direct energy consumption, we miss the full picture. We need frameworks that capture both the operational cost and the systemic benefit. This is where life cycle assessment combined with comparative modeling becomes essential. We need to ask: compared to what? And over what timeframe? The sectoral success stories are compelling when you run the numbers: Building automation systems powered by AI are consistently achieving energy savings in the range of 20-30% across diverse building types. One documented case study of a commercial office building in the United States showed a 32% reduction in overall energy consumption with a 2.4-year return on investment (a $2.1 million system investment generating $875,000 in annual savings). In Stockholm, the SISAB school building portfolio achieved similar results with a two-year payback period. In precision agriculture, AI-driven irrigation and fertilizer application systems are cutting water consumption by 20% to as much as 50% and reducing chemical runoff, addressing both resource scarcity and ecosystem health. Waste management optimization is another powerful example. AI-powered sorting systems in recycling facilities dramatically improve material recovery rates while reducing contamination. The resource efficiency gains far exceed the AI system's energy footprint. These aren't marginal improvements. When properly deployed, targeted AI applications produce emissions savings and resource efficiencies that dwarf their own operational costs. That being said, given today's fossil fueled data center expansions, we may find that we have much further to go in making the environmental positives outweigh the negatives. But that's no reason to throw in the towel or to assume that these technologies cannot - over time - deliver more environmental benefits than downsides. It requires companies to demand more of their technology providers and deploy their systems sustainably when greener options become available. But (and this is crucial) these benefits only materialize when we pair the right AI with the right infrastructure and the right deployment strategy. Which brings us to governance. The Path Forward: Governance, Transparency, and Adaptive Thinking The sustainability community, including organizations like ISSP, is actively developing shared frameworks for assessing AI's net impact. These emerging approaches include system-level energy auditing, selective task deployment protocols, and strategies for minimizing "dark data" (the vast amounts of stored data that's never used but still requires energy to maintain). Multi-stakeholder governance initiatives are bringing together technologists, policymakers, environmental scientists, and business leaders to create adaptive standards. This isn't about creating rigid regulations that will be obsolete in two years. It's about establishing principles and processes that evolve with the technology. Those with a technology management background know that the most successful systems are those designed for adaptation. We need governance structures that can respond to new information, course-correct quickly, and remain grounded in measurable outcomes. Transparency is non-negotiable. Organizations deploying AI need to measure and report not just their energy consumption but their net impact. What problems are you solving? What resources are you saving? What would the alternative approach have cost? These aren't easy questions, but they're the right ones. As sustainability professionals, this is our arena. We have the frameworks: life cycle thinking, systems analysis, stakeholder engagement, and metrics development, to name a few. We need to apply these tools to AI with the same rigor we've applied to supply chains, built environments, and industrial processes. So here's my invitation: What are you seeing in your sector? How is your organization approaching the AI sustainability question? Are you finding innovative ways to ensure deployment is appropriate and responsible? Because ultimately, appropriate AI isn't about choosing between progress and sustainability. It's about insisting that progress is sustainable. It's about right-sizing models, optimizing infrastructure, measuring net benefit, and building governance systems worthy of the challenge. The technology itself is neutral. Our choices determine whether AI becomes a driver of sustainability or another extractive burden. Let's choose wisely.
