In a move that signals a significant shift in how the entertainment industry is grappling with the climate crisis, Emma Stewart, the high-profile Chief Sustainability Officer (CSO) at Netflix, has announced her departure from the streaming titan. After nearly six years of steering the company toward a more sustainable operational model, Stewart is transitioning to a leadership role at Climate Spring, a social enterprise dedicated to fundamentally altering how climate change is depicted in global film, television, and popular culture.
The departure marks the end of a transformative era at Netflix, where Stewart was instrumental in bridging the gap between cold, hard corporate decarbonization and the cultural influence of the world’s largest entertainment platform.
The Core Facts: A Career Defined by Impact
Emma Stewart joined Netflix in 2020, transitioning from a senior role at the consultancy Engie Impact. Her mandate was clear: to manage the environmental footprint of a company that produces thousands of hours of content across 190 countries. However, Stewart quickly realized that for a company like Netflix, the "product"—the stories themselves—held as much potential for climate impact as the power consumption of its server farms or production sets.
During her tenure, Stewart oversaw a dual-track strategy. Operationally, she led the charge to reduce the company’s Scope 3 emissions, which account for over 95 percent of its total carbon footprint. Culturally, she turned the spotlight on "sustainability storytelling," effectively turning the platform into a massive classroom for climate awareness. By the time of her departure, she had personally advised on hundreds of scripts and helped grow the Netflix Sustainability Stories Collection to over 200 titles.
Her new role at Climate Spring represents a "doubling down" on this cultural strategy. Climate Spring operates at the intersection of media and advocacy, providing the industry with the tools, research, and funding necessary to weave climate-conscious narratives into everything from crime thrillers to romantic comedies.
A Chronology of Change (2020–2026)
The trajectory of Stewart’s work at Netflix provides a blueprint for how modern corporations can integrate sustainability into creative business models.
- 2020: Stewart joins Netflix as the company’s first CSO. She immediately begins auditing the environmental impact of physical production, identifying diesel-powered generators on film sets as a primary culprit in Scope 3 emissions.
- 2021: The company announces its "Net Zero + Nature" plan. Stewart positions Netflix as a leader in transparency, publishing detailed reports on the carbon intensity of productions.
- 2023: The "Sustainability Stories Collection" is expanded significantly, signaling a shift from just measuring emissions to leveraging the platform’s massive audience to normalize climate-friendly behaviors.
- 2025: The June sustainability report is released, highlighting a 14 percent reduction in Scope 3 emissions intensity. While the path remains long, industry analysts point to this as a significant milestone for a company that was, until recently, largely ignoring the carbon cost of its physical sets.
- July 2026: Stewart announces her resignation to join Climate Spring, shifting her focus from internal corporate management to the broader, systemic influence of media narrative.
Supporting Data: The Scope 3 Challenge
To understand the weight of Stewart’s work at Netflix, one must look at the data. Netflix’s emissions profile is atypical for a tech company. While most streaming services are concerned with the energy consumption of data centers, Netflix’s physical footprint is tied to the production of movies and series.
According to the most recent Environmental, Social, and Governance (ESG) report published in June 2026, the company’s Scope 3 emissions stand at approximately 1 million metric tons of carbon dioxide equivalent. These emissions are largely driven by the logistical complexity of global filming, including travel, shipping, and the historically heavy reliance on diesel generators to power lighting and camera equipment on location.
Netflix has committed to a 55 percent reduction in Scope 3 intensity between 2019 and 2030. At 14 percent progress, the company remains "on track." However, the difficulty of this goal cannot be overstated. Decarbonizing a film set requires a massive, industry-wide shift toward battery storage and grid-tied power—a transition that Stewart championed by pushing for electrification across global production hubs.
The Philosophy of "Climate Spring": Shifting the Narrative
Stewart’s move to Climate Spring is not a retreat from the problem; it is a tactical expansion. Climate Spring’s philosophy is rooted in the idea that stories change minds. By embedding climate themes into the fabric of popular entertainment, the organization aims to bypass the "preachiness" of documentaries and influence audiences through the media they already love.
The organization is currently involved in over 60 active projects. Their model is multifaceted:
- Training: Providing writers and showrunners with the vocabulary and research to integrate climate themes naturally.
- Funding: Offering "seed" capital to develop scripts that might otherwise be deemed "too risky" or "too niche" by traditional studio executives.
- Consulting: Serving as a bridge between scientific data and creative writers to ensure climate-related plot points are grounded in reality without sacrificing drama.
"It is not about turning every movie into a lecture," a source familiar with Climate Spring’s operations noted. "It is about ensuring that when a character is faced with a choice, the climate context—the heatwaves, the energy transitions, the environmental justice issues—is as real and present as the character’s personal struggle."
Implications: The Future of Media and Sustainability
Stewart’s transition signals a growing trend: the professionalization of "climate consulting" in Hollywood. For years, environmentalism in film was largely symbolic or restricted to the documentary genre. Today, as climate change becomes a lived reality, studios are realizing that ignoring the climate in contemporary storytelling is a failure of realism.
The Corporate Perspective
For Netflix, the challenge will be maintaining the momentum Stewart built. The internal sustainability team must now prove that the initiatives she set in motion—from the electrification of sets to the internal carbon pricing models—can survive without her direct oversight. The "Sustainability Stories Collection" will serve as a litmus test; if the curation of these stories drops off, it may signal a corporate retreat from the values Stewart fought to embed.
The Cultural Impact
The broader implication for the industry is that sustainability is no longer just about "going green" behind the scenes; it is about "going green" on the screen. If Climate Spring, now bolstered by Stewart’s experience at the highest level of corporate media, succeeds in influencing major showrunners, we may soon see a sea change in how climate is portrayed. This could move the needle from "apocalyptic disaster movie" tropes to stories that explore climate solutions, adaptation, and the psychological impacts of a changing planet.
Conclusion: A Legacy of Influence
Emma Stewart leaves behind a complex legacy at Netflix. She transformed the way the world’s largest streamer accounts for its carbon, forcing a massive, decentralised creative organization to look at its own supply chain with scientific rigor. Yet, her move to Climate Spring suggests that she believes the greatest tool for climate action is not the boardroom, but the screen.
As the industry watches her transition, the message is clear: the climate crisis is not just an engineering problem to be solved with better batteries or renewable energy. It is a narrative challenge. By moving to the front lines of story development, Stewart is betting that the most powerful way to change the world is to change the stories we tell about it.
As we look toward the remainder of the decade, the success of this pivot will be measured not just in carbon tons, but in the evolving conscience of global audiences who, through the shows they watch, may finally begin to see the climate crisis for what it is: the defining story of our time.
