Every year, the editorial team at MIT Technology Review undertakes a massive, months-long endeavor to identify the world’s most promising young minds. The resulting "Innovators Under 35" list is more than a collection of biographies; it serves as a barometer for the future of global technology. This year, the focus on the climate and energy sector—comprising nine standout individuals—reveals a stark, nuanced reality: the fight against climate change is no longer just about renewable energy generation. It is about the fundamental reconfiguration of industrial materials, the intelligent application of artificial intelligence, and the radical rethinking of the global supply chain.
Main Facts: A New Breed of Climate Problem Solvers
The 2026 cohort represents a departure from the "solar-and-wind-only" narrative that dominated climate discourse for the last decade. Instead, these innovators are targeting the "invisible" emissions—those embedded in heavy industry, cooling systems, and material extraction.
The nine climate and energy awardees are tackling the challenge from three distinct pillars:
- AI-Integrated Climate Mitigation: Using machine learning to optimize existing systems and reduce the energy footprint of the digital revolution itself.
- Resource Security: Developing novel methods to extract the critical minerals—lithium, copper, and others—that are the lifeblood of the battery-powered transition.
- Industrial Circularity: Moving beyond traditional recycling to address the carbon intensity of steel production, plastic manufacturing, and food waste management.
Chronology of the 2026 Selection Process
The path to the 2026 list began in late 2025, with an open call for nominations that spanned six continents. The editorial team received thousands of applications, which were then vetted through a rigorous multi-stage process:
- Phase 1 (October–December 2025): Preliminary screening focused on technical feasibility and the potential for large-scale impact.
- Phase 2 (January–March 2026): Deep-dive interviews with subject-matter experts and peers of the nominees to verify claims and assess the originality of their research.
- Phase 3 (April–May 2026): Final editorial review, where the team looked for thematic overlaps, leading to the identification of the four core categories: Biotech, Climate and Energy, Computing and Robotics, and AI.
- Phase 4 (June 2026): The official unveiling of the list, coinciding with an analysis of how these innovators define the trajectory of their respective fields.
The AI Paradox: Energy Footprint vs. Climate Tool
Artificial Intelligence is the dominant technological story of this decade, acting as both a primary driver of energy demand and a vital tool for environmental management. The 2026 list highlights this duality with sobering clarity.
The Energy Cost of Intelligence
The sheer energy intensity of Large Language Models (LLMs) and generative AI has created a new category of carbon emissions. Jae-Won Chung, one of this year’s standout innovators, has dedicated his work to mitigating this impact. By developing software that meticulously measures the energy demands of open-source models, Chung is providing the transparency necessary to regulate and improve AI efficiency. His work echoes the findings of MIT Technology Review’s 2025 investigation into the hidden climate footprint of Big Tech, proving that we cannot optimize what we do not measure.
AI as the Great Climate Optimizer
Conversely, AI is being deployed as a precision instrument to combat the climate crisis. Jing Wei is utilizing machine learning to synthesize disparate data points from satellites, weather stations, and ground sensors to track pollution with unprecedented accuracy. By "filling in the gaps" where traditional monitoring fails, Wei allows for targeted policy interventions. Similarly, Zhonghua Zheng has addressed the "urban blind spot" in climate modeling. Traditional models often struggle with the complex heat-island dynamics of cities; Zheng’s AI-driven approach provides localized, actionable climate projections that help urban planners design more resilient, energy-efficient infrastructure.
Critical Materials and the Supply Chain Crunch
As the world pivots away from fossil fuels, it is pivoting toward minerals. The global transition is essentially a metal-intensive endeavor, and the 2026 innovators are addressing the looming supply crises in lithium and copper.
Innovation in Extraction
Lithium-ion batteries are the cornerstone of the grid and the automotive sector. However, the current methods of lithium extraction are environmentally destructive and slow. Mohammad Alkhadra, CEO of the startup Lithios, is pioneering an electrochemical process to extract lithium from brine. By moving away from slow-moving evaporation ponds, Alkhadra’s method is significantly faster and less invasive to local ecosystems.
The Hardrock Challenge
While brine is currently cheaper, hardrock ore remains a major source of the metal. Benjamin Mowbray, CTO of Rock Zero, is tackling the cost and environmental issues associated with traditional hardrock mining. His company’s process aims to refine the extraction of lithium from ore in a way that minimizes energy consumption and waste, ensuring that the supply chain for electric vehicles can keep pace with projected demand.
Supporting Data: Why Industrial Overhaul is Non-Negotiable
The urgency behind these innovations is backed by sobering statistics:
- Steel Production: Accounts for approximately 7% of global greenhouse gas emissions. Laureen Meroueh is challenging this by developing a new furnace design that simplifies the chemical reduction of iron ore, aiming to produce cleaner, cheaper steel.
- Plastics and Packaging: The reliance on fossil-fuel-derived plastics is being challenged by Joseph Nguthiru, who is transforming invasive weeds into sustainable, bioplastic packaging.
- Cooling and Refrigeration: Refrigerants are potent greenhouse gases that often leak into the atmosphere. Jinyoung Seo is developing solid-state refrigerants that promise to eliminate leakage while reducing energy consumption by 20% compared to current gas-based systems.
- Aquaculture: Diana Orembe is tackling food waste by repurposing it into nutrient-rich fish feed, effectively closing a loop that would otherwise result in methane emissions in landfills.
Official Responses and Strategic Implications
The MIT Technology Review editorial team emphasizes that these 35 innovators represent a "zoom-out" moment for climate tech. The collective work of these young researchers suggests that we are entering a phase of "Systemic Optimization."
"When you look at these innovators together," says the editorial team, "the takeaway is clear: the low-hanging fruit of decarbonization—simple renewable generation—is no longer enough. We are now in the phase of fixing the ‘plumbing’ of the global economy."
The implications are twofold:
- Capital Allocation: Venture capital and government grants are increasingly shifting toward "hard tech"—materials science, industrial manufacturing, and AI-enhanced logistics—rather than pure software-based climate solutions.
- Policy Shifts: Policymakers are realizing that net-zero targets cannot be achieved by grid-decarbonization alone. The innovations presented by Meroueh (steel) and Seo (refrigerants) highlight the need for industrial policy that incentivizes the decarbonization of heavy manufacturing.
Conclusion: The Path Ahead
The 2026 MIT Technology Review list provides a roadmap for a world in transition. The innovators featured are not merely dreamers; they are pragmatic engineers and scientists who recognize that the climate crisis is a complex systems problem. From the energy-hungry servers of AI to the invasive weeds of our packaging, every corner of our society is currently under a "green audit."
As we look toward the remainder of the decade, the success of these individuals will likely determine whether the global economy can successfully decouple growth from carbon emissions. Their work serves as a reminder that while the climate challenge is daunting, the ingenuity of the next generation is equally vast, focused, and, crucially, already in the lab.
