The global transition toward a sustainable, net-zero economy is not merely a technological challenge; it is a human one. As the urgency of the climate crisis intensifies, the mantle of leadership is increasingly being passed to a generation of professionals who view sustainability not as a peripheral corporate goal, but as the core engine of modern business. For nearly a decade, the Trellis 30 Under 30 list has served as the definitive chronicle of this shift, identifying the young trailblazers who are turning ambitious climate goals into measurable, real-world impact.
Today, Trellis officially announces the search for its 2026 cohort. We are seeking the next wave of innovators, strategists, and disruptors who are reshaping industries ranging from finance and industrial decarbonization to circular economy logistics and nature-based solutions.
A Legacy of Impact: The Chronology of Innovation
Since its inception in 2016, the Trellis 30 Under 30 initiative has spotlighted 300 individuals who have defied the conventional limits of their professional roles. The program was born from a simple observation: while executive leadership often takes the spotlight, the most granular, critical work—the kind that actually moves the needle on carbon emissions and resource efficiency—is frequently executed by professionals in the earlier stages of their careers.
Over the past nine years, the list has evolved alongside the climate tech landscape. In the early years, the focus was often on foundational renewable energy projects and nascent ESG reporting standards. By 2020, the conversation had shifted toward supply chain transparency and the complexities of Scope 3 emissions. Today, the criteria reflect the maturity of the market, prioritizing those who can demonstrate deep, systemic changes within their organizations.
The 2025 cohort serves as a testament to this breadth. Consider Marlies Michielssen of Amazon, whose work in water replenishment has restored hundreds of millions of liters in water-stressed regions, proving that corporate giants can pivot toward regenerative resource management. Or look to Mathew Lee at MSCI, who has bridged the gap between complex climate data and investment decision-making, helping the world’s largest asset managers understand the financial materiality of sustainability. Finally, the work of Clausell Stokes—co-founder of the Ceres working group on sustainable and resilient agriculture—highlights the power of collaboration, bringing industry titans like Nestlé, McDonald’s, and Keurig Dr Pepper to the table to solve for systemic agricultural degradation.
The Metrics of Change: How We Evaluate Excellence
What distinguishes a Trellis 30 Under 30 honoree from a general high-achiever? The Trellis content team employs a rigorous evaluation process that prioritizes tangible outcomes over aspirational rhetoric. We are not looking for people who simply "care about the planet"; we are looking for individuals who have identified a specific, measurable problem and have executed a strategy to address it within their professional capacity.

The Evaluation Framework
The core of our selection process rests on three pillars:
- Specificity of Impact: Candidates must demonstrate a clear "before and after." Whether it is a reduction in carbon output, a quantifiable increase in material circularity, or the implementation of a new sustainability framework that influences capital allocation, the impact must be traceable.
- Professional Influence: We assess how the individual has navigated their specific organizational or industry environment to achieve these goals. This includes their ability to influence internal stakeholders, bridge departmental silos, and scale their solutions across their wider sector.
- Innovation in Strategy: The climate crisis demands novel solutions. We look for those who have challenged "business as usual," whether through the deployment of cutting-edge climate tech or the radical redesign of traditional business models.
The selection process is a collaborative effort involving our editorial team, industry experts, and a review of documented achievements. We ensure that the list remains diverse, representing the global nature of the climate challenge and the various sectors—from policy and finance to engineering and supply chain management—that must work in concert to achieve net-zero targets.
Supporting Data: Why the Under-30 Demographic Matters
The urgency of the climate crisis is often measured in decades, but the window for effective action is measured in months and years. According to recent reports from the International Energy Agency (IEA) and the Intergovernmental Panel on Climate Change (IPCC), the period between 2025 and 2030 is critical for keeping the 1.5°C goal within reach.
This period coincides with the professional prime of the "Gen Z" and "Millennial" workforce. Data indicates that professionals under the age of 30 are more likely to prioritize sustainability in their career choices, often acting as "internal activists" who drive corporate sustainability programs from the bottom up. By identifying these leaders, Trellis provides a roadmap for the rest of the industry, showcasing the specific tools, technologies, and strategies that are proving successful today.
Official Perspectives: The Value of Recognition
The Trellis editorial team, led by veterans in the sustainability space like Heather Clancy and Katie Ryan, views this project as a vital service to the climate community.
"Recognizing these individuals is about more than just accolades; it’s about creating a peer network of leaders who can support one another as they scale their impact," says Heather Clancy, an expert whose career has been dedicated to chronicling the intersection of technology and the environment.

Katie Ryan, who brings a background in systems thinking and corporate sustainability to the team, emphasizes the necessity of inclusivity in this process. "We believe in the power of agency. By highlighting the successes of young leaders from diverse backgrounds and sectors, we hope to demonstrate that everyone, regardless of their specific role, has the capacity to take positive action. Our goal is to provide the energy and the inspiration for the next wave of climate professionals to step into their own power."
The Path Forward: Implications for the 2026 Cohort
The announcement of the 2026 class in October will represent more than just a list of names. It will be a barometer for where the climate sector is heading. We anticipate that this year’s submissions will show a greater emphasis on AI-driven climate solutions, the integration of biodiversity metrics into financial reporting, and a continued focus on the "Just Transition"—ensuring that the shift to a green economy is equitable for workers and communities globally.
For those considering an application, the message is clear: do not focus on your tenure or your job title. Focus on your contribution. Whether you are an engineer optimizing industrial heating processes, a finance professional structuring green bonds, or a supply chain manager tracking Scope 3 data, your work is a critical piece of the global puzzle.
How to Participate
The application window is currently open. We invite all eligible professionals to submit their credentials via the official portal by the September 11, 2026, deadline.

The climate crisis is arguably the most complex systemic challenge in human history. It requires the energy, the audacity, and the intellectual rigor of those who are just now hitting their professional stride. We invite you to share your story, demonstrate your impact, and join a community that is quite literally building the future of our planet.
As we look toward 2026, we remain steadfast in our commitment: to find the people who are not just talking about the future, but are actively writing it. We look forward to reading your applications.
