In the world of marketing, buzzwords come and go — but “green marketing” and “sustainability communications” are terms that have stuck with me, not just as trends, but as defining themes throughout my career. They’re what I call hourglass terms — concepts that begin broadly, narrow into a specialized niche, and then fan out again to influence a wide range of industries, sectors, and communication needs.

Let me explain — and take you on a journey through how I came to specialize in this growing, evolving, and deeply meaningful space.

What Is Green Marketing, Exactly?

At its core, green marketing refers to promoting products, services, or practices that are environmentally friendly. It’s about more than slapping a green label on a package — it’s a commitment to transparency, sustainability, and often, behavioral change. Green marketing focuses on aligning brand values with environmental ethics, creating campaigns that both inform and inspire.

Sustainability communications, meanwhile, goes beyond the consumer angle. It encompasses the storytelling, messaging, and strategic outreach that organizations use to engage stakeholders — from the public to policymakers — on environmental initiatives, sustainable practices, climate resilience, and more.

Together, these two disciplines span a massive spectrum — from technical communications about carbon reporting to grassroots storytelling about tree planting or water conservation. Hence the hourglass.
