Executive Overview
As the global climate crisis accelerates, the demand for transformative, measurable action has never been more urgent. While high-level international summits and corporate boardrooms set ambitious net-zero targets, the heavy lifting of execution, innovation, and systemic reform is increasingly driven by a new generation of professionals. Enter the Trellis 30 Under 30—an annual initiative that has spent nearly a decade identifying, spotlighting, and celebrating the brilliant young minds engineering a sustainable future.
Since its inception in 2016, the program has recognized 300 innovators, trailblazers, and corporate changemakers whose professional contributions have yielded direct, tangible, and measurable impacts in the fight against climate change. From pioneering scalable carbon removal technologies and designing circular economies to spearheading industrial decarbonization and transforming corporate finance, these young leaders are redefining what it means to work in sustainability.
Now, as the organization looks toward the horizon, the official call for the 2026 Trellis 30 Under 30 cohort has officially opened. With a strict application deadline of September 11, the search is on for the next wave of disruptors who are not just talking about the future of the planet, but actively building it. Selected candidates will be notified before the end of September, with the official class announcement slated for October.
This comprehensive report explores the evolution of the Trellis 30 Under 30 initiative, highlights the caliber of past honnores who are reshaping industries, outlines the rigorous evaluation process for the upcoming cohort, and examines the broader implications of youth-led leadership in the global corporate and environmental landscape.
Detailed Chronology: A Decade of Recognizing Youth-Led Climate Action
The Genesis (2016): Planting the Seeds of Change
When the 30 Under 30 franchise was first established in 2016, the corporate sustainability landscape looked profoundly different. Environmental, Social, and Governance (ESG) metrics were often viewed as peripheral corporate social responsibility (CSR) initiatives rather than core financial drivers. Recognizing that a new breed of digitally native, systems-thinking professionals was entering the workforce, the leadership at Trellis envisioned a platform to elevate those whose work bypassed corporate greenwashing and delivered hard, quantifiable environmental metrics.
Scaling the Impact (2017–2020)
Over the next four years, the initiative expanded its scope to mirror the rapidly evolving climate technology sector. What began primarily as a nod to renewable energy advocates and conservationists quickly broadened to include pioneers in:
- Carbon dioxide removal (CDR) and direct air capture (DAC) technologies.
- Circular economy frameworks, shifting linear "take-make-waste" models into regenerative loops.
- Low-carbon materials science, revolutionizing construction, textiles, and manufacturing.
- Climate tech venture capital and sustainable finance instruments.
During this period, honorees were instrumental in helping traditional Fortune 500 companies navigate shifting regulatory landscapes, translating complex environmental data into actionable enterprise strategies.
Maturing into a Global Vanguard (2021–Present)
Entering the 2020s, the urgency of the climate crisis transformed sustainability from a corporate strategy into an existential operational imperative. The Trellis 30 Under 30 evolved accordingly. The program began highlighting multidisciplinary disruptors—individuals working at the intersection of artificial intelligence and grid management, supply chain transparency, and climate justice communications.
By the time the 2025 cohort was inducted, the program had celebrated 300 distinct individuals whose collective professional footprint spans multinational tech giants, agile climate-tech startups, global financial institutions, and influential non-profit coalitions. The upcoming 2026 cohort aims to build directly upon this rich legacy, seeking out practitioners who can demonstrate undeniable proof of concept and scaled environmental impact in their daily roles.
Supporting Context & Metrics: Case Studies from the Frontlines
To truly understand the value of the Trellis 30 Under 30, one must look at the nature of the work being honored. The initiative does not reward vague intentions or passion projects; it evaluates professionals based on the direct, measurable impact they make within their professional employment.
The 2025 cohort offers a masterclass in the types of systemic interventions the Trellis editorial and content teams look for:
1. Marlies Michielssen (Amazon)
Operating within one of the world’s most complex logistics and technology supply chains, Marlies Michielssen has tackled one of the most critical environmental challenges of our time: freshwater security. Michielssen has successfully identified, structured, and overseen water replenishment projects designed to restore hundreds of millions of liters of water annually in severely water-stressed regions. Her work moves beyond corporate water-use efficiency, focusing instead on active watershed restoration and community-based resilience, proving that massive tech enterprises can actively heal the ecosystems they touch.
2. Mathew Lee (MSCI)
While engineers and scientists build green infrastructure, financial markets decide whether it scales. Mathew Lee, a researcher at MSCI, works at the vital intersection of sustainability and global capital markets. Lee develops analytical frameworks and research that help the world’s largest institutional investors answer a fundamental, high-stakes question: Why does sustainability matter for portfolio risk and long-term value creation? By translating climate science and social governance metrics into rigorous financial intelligence, Lee influences how trillions of dollars are deployed across global economies.
3. Clausell Stokes (Ceres Working Group)
Systemic transformation requires radical collaboration across historically siloed competitors. Clausell Stokes co-founded the Ceres working group on sustainable and resilient agriculture—a powerful coalition that brings together corporate behemoths such as McDonald’s, Nestlé, and Keurig Dr Pepper. Stokes has been instrumental in aligning these agricultural giants around shared targets for soil health, regenerative farming practices, and supply chain emissions reduction, driving agricultural reform across millions of acres of farmland.
These profiles illustrate the core ethos of the Trellis 30 Under 30: whether through hydrological restoration, financial data modeling, or cross-sector agricultural coalitions, the honorees are individuals whose professional footprint is visibly altering the trajectory of global industries.
Official Statements and Evaluation Framework
The search for the 2026 cohort is spearheaded by the experienced editorial and content teams at Trellis, supported by veteran environmental journalists and strategists such as Heather Clancy and Katie Ryan.
The Evaluation Methodology
Unlike awards that rely solely on popularity, peer nominations, or résumé padding, the Trellis evaluation framework is rooted in rigorous journalism and empirical assessment. The content team evaluates applicants based on their recent, tangible contributions within their professional employment.
While the precise criteria emphasize depth over breadth, candidates are generally measured against the following key performance indicators:
- Directness of Impact: Did the nominee play a primary, driving role in the initiative, or were they merely a peripheral team member?
- Measurability: Can the results of their professional work be quantified? (e.g., tons of carbon removed, liters of water saved, capital mobilized, percentage reduction in supply chain emissions).
- Scalability & Innovation: Does their solution offer a blueprint that can be replicated across their industry or the broader global economy?
- Professional Tenacity: How has the nominee overcome institutional hurdles, regulatory resistance, or technological roadblocks to achieve their goals?
Key Dates for the 2026 Cohort
- Application Deadline: September 11
- Notification Window: On or before the end of September
- Public Announcement: October

Future Outlook: The Role of Young Professionals in the Next Era of Climate Action
As the world confronts the realities of a rapidly warming planet, the corporate and technological responses are shifting from target-setting to aggressive accountability. In this next era, the traditional top-down corporate hierarchy is proving insufficient. The agility, technical literacy, and uncompromising ethical clarity of young professionals are vital antidotes to corporate greenwashing and bureaucratic inertia.
Programs like the Trellis 30 Under 30 serve a function far greater than mere recognition; they construct a vital professional network. By connecting these brilliant young minds, Trellis is helping to forge a cohesive, cross-industry coalition of leaders who will occupy chief sustainability officer roles, helm climate-tech funds, and draft environmental policy over the coming decades.
The challenges of 2026 and beyond—ranging from managing climate migration and avoiding ecological tipping points to financing a just energy transition—will require unprecedented levels of innovation. If the past 300 honorees are any indication, the future of global sustainability is in exceptionally capable hands.
Are you—or a brilliant colleague under the age of 30—making a measurable, direct impact on climate change through your professional work? Ensure your voice is heard by submitting an application to the 2026 Trellis 30 Under 30 Cohort before the September 11 deadline.
