We have economists. Scientists. Physicists. Artists. Each of these “-ists” represents more than a job title. They signal a way of thinking, a discipline, and a commitment to applying knowledge responsibly in the real world. Sustainability deserves the same level of clarity and credibility.

That’s why I want to introduce—and intentionally coin—a new word: sustainablist. A sustainablist is not someone who simply cares about sustainability. A sustainablist is someone who acts accordingly, bringing sustainability into everyday decisions, tradeoffs, and priorities using evidence, experience, and practical judgment—with an explicit awareness that today’s decisions shape tomorrow’s outcomes.

Why we need a new word

“Sustainability” has become one of the most overused—and misunderstood—terms in business. Too often it’s framed as marketing, a compliance exercise, or a side initiative owned by one department. In reality, sustainability done well is none of those things.

It is a discipline.

Like economics or science, sustainability requires structured thinking across time. A sustainablist understands how environmental, social, and governance factors intersect with operations, costs, risks, workforce realities, and long-term value creation. They don’t ask whether something is simply “green.” They ask whether a decision reduces waste, lowers risk, controls cost, strengthens resilience, and avoids creating future liabilities that someone else will eventually have to manage.

What defines a sustainablist?

What defines a sustainablist is less about credentials and more about mindset and behavior. Sustainablists think in systems rather than silos, and across time rather than just the next quarter. They look beyond short-term wins to long-term outcomes, recognizing that many of the most expensive business problems are simply the delayed consequences of earlier decisions.

They rely on data rather than slogans and understand that sustainability is about tradeoffs, not perfection. Most importantly, a sustainablist recognizes that sustainability is not political. It is operational and financial. Just as workplace safety, quality control, or financial governance are about protecting an organization’s future viability, sustainability is a practical response to long-term risks, resource constraints, and responsibility.

Sustainablists are already among us

You don’t need “sustainability” in your job title to be a sustainablist.

They show up as operations leaders reducing energy, water, and material waste because inefficiency today becomes cost tomorrow. They appear in procurement teams asking better questions about suppliers and materials to avoid future supply disruptions, reputational risk, or stranded investments. They work in finance departments that recognize environmental and social risks as genuine business risks.

Facility and fleet managers who extend asset life rather than replace equipment prematurely are sustainablists in practice. So are mid-level managers quietly driving change without formal authority, aware that inaction today often means fewer options tomorrow.

Not activists. Not perfectionists

A sustainablist is neither an activist shouting from the sidelines nor a perfectionist demanding instant transformation. Sustainablists are pragmatic. They understand that meaningful progress happens step by step, guided by measurement, prioritization, and continuous improvement.

They focus on what can be improved now while laying groundwork for what must change next. They make decisions with an eye not just on current performance, but on how those decisions will affect the organization, its people, and its stakeholders years down the road.

Why sustainablists matter—especially now

As reporting requirements expand, customer expectations evolve, and environmental and social risks intensify, organizations don’t need more buzzwords. They need people who can translate sustainability into action—today and over time.

They need sustainablists—those professionals who understand that sustainability is fundamentally about future-readiness.

They need people who connect sustainability to business fundamentals, manage risk intelligently, and help organizations remain resilient, credible, and competitive in a world that will look quite different from the one it does today.

So, are you a sustainablist?

If you care deeply about the impact of decisions, use evidence instead of ideology, believe sustainability should make organizations stronger rather than weaker, and consider how today’s choices shape tomorrow’s realities, you may already be one.

It’s time we had a word for that. Welcome to sustainablism.
