In a significant leadership transition for the streaming sector, Emma Stewart, the Chief Sustainability Officer (CSO) at Netflix, has announced her resignation. After nearly six years of steering the streaming giant through a complex transition toward net-zero operations, Stewart is stepping down to join the leadership team at Climate Spring. This move signals a strategic shift in her career, moving from the internal mechanics of corporate decarbonization to the external, cultural influence of storytelling in film and television.
The Departure: A New Chapter in Cultural Advocacy
Stewart’s tenure at Netflix, which began in 2020, marked a pivotal period for the company. Hired from the consultancy Engie Impact, Stewart was tasked with the daunting responsibility of institutionalizing sustainability within a company whose primary product—digital entertainment—is often overlooked in the broader discussion of industrial carbon footprints.
In a candid LinkedIn post announcing her departure, Stewart reflected on her journey, highlighting that her work extended far beyond carbon accounting. During her tenure, she advised on hundreds of film and television scripts, ensuring that climate themes were woven into the fabric of popular culture rather than relegated to niche documentaries. She also oversaw the expansion of Netflix’s "Sustainability Stories Collection," a curated library that grew to include more than 200 titles available to viewers in 190 countries.
Her transition to Climate Spring—a social enterprise dedicated to changing how climate change is represented in popular media—suggests a pivot toward systemic cultural change. Climate Spring operates at the intersection of creative arts and environmental activism, offering training to writers, funding early-stage project development, and providing climate-focused consulting for major productions. With over 60 active projects ranging from gritty crime dramas to lighthearted romantic comedies, the organization aims to normalize climate narratives across all genres.
Chronology: Six Years of Corporate Climate Evolution
To understand the impact of Stewart’s work, one must look at the timeline of Netflix’s environmental evolution under her guidance.
- 2020: Emma Stewart joins Netflix as its first Chief Sustainability Officer. At the time, the company was under pressure to quantify the environmental impact of its massive data center operations and physical production sets.
- 2021: Netflix launches its "Net Zero + Nature" initiative, a comprehensive plan to achieve net-zero greenhouse gas emissions by the end of 2022. This period saw a massive audit of the company’s Scope 1, 2, and 3 emissions.
- 2022–2023: The company begins the difficult process of replacing diesel generators on production sets with battery-electric and renewable alternatives. Stewart becomes a visible advocate for "green production" standards across the industry.
- 2024: Netflix’s Sustainability Stories Collection reaches a global milestone, proving that climate-themed content can achieve high viewership numbers, effectively debunking the myth that "green" content doesn’t sell.
- June 2026: Netflix releases its latest Environmental, Social, and Governance (ESG) report, highlighting steady, if incremental, progress toward long-term goals.
- July 2026: Emma Stewart officially departs the company to join Climate Spring, marking the end of her six-year tenure.
Supporting Data: The Scope 3 Challenge
While Stewart’s success in cultural storytelling was highly visible, her most difficult work occurred behind the scenes. Netflix, like many multinational corporations, faces the "Scope 3" challenge—emissions that occur in the value chain, which are often outside of the company’s direct control.
For Netflix, Scope 3 emissions account for more than 95 percent of its total carbon footprint, totaling approximately 1 million metric tons of carbon dioxide equivalent annually. A significant portion of this is generated by the energy-intensive nature of physical film production, specifically the use of diesel generators on remote sets.
According to the 2025 ESG report released in June, Netflix has committed to reducing its Scope 3 intensity by 55 percent between 2019 and 2030. As of mid-2026, the company reported a 14 percent reduction. While some critics argue this pace is slow, the company maintains that it is "on track," citing the logistical complexities of transitioning global production infrastructure to renewable energy sources. Stewart’s leadership was central to these efforts, pushing for industry-wide standards that would make sustainable production the norm rather than the exception.
Official Responses and Industry Context
The departure of a high-profile sustainability officer often triggers speculation regarding a company’s future priorities. However, industry analysts view Stewart’s move to Climate Spring as an evolution of the work she started at Netflix.
"Emma has been a visionary," said an industry spokesperson close to the production sector. "She moved the needle from ‘how do we stop using diesel’ to ‘how do we make climate change a character in our stories.’ Her move to Climate Spring is a logical progression—she is now scaling that cultural influence beyond just one company to the entire entertainment industry."
Climate Spring’s leadership welcomed the announcement, noting that Stewart’s expertise in both corporate strategy and creative consulting would be "transformative" for their mission. By embedding climate science into the scripts of popular culture, Climate Spring aims to reach audiences that traditional environmental documentaries often fail to engage.
Implications: The Future of "Green" Entertainment
The implications of Stewart’s move are twofold. First, for Netflix, the departure leaves a vacancy that will test the company’s commitment to its long-term climate goals. The next CSO will need to balance the ongoing, labor-intensive decarbonization of global production sets with the high-level cultural strategy that Stewart established.
Second, the broader entertainment industry stands to benefit from this shift. By joining Climate Spring, Stewart is positioning herself to influence a much wider array of studios and creators. If the goal of the climate movement is to reach the general public, pop culture is arguably the most powerful medium available.
As we look toward the 2030 climate milestones, the role of media is becoming increasingly clear. Scientists have long argued that facts alone are insufficient to drive behavioral change; stories, emotions, and character-driven narratives are required to make the climate crisis feel personal. By transitioning from the corporate boardroom to the creative development studio, Stewart is betting that the most effective way to combat climate change is to change the stories we tell ourselves.
Conclusion
Emma Stewart’s six years at Netflix leave a legacy of dual progress: a more systematic, data-driven approach to production emissions and a new, global standard for how climate issues are integrated into popular entertainment. As she embarks on her new role at Climate Spring, the industry will be watching closely to see if the "climate-literate" storytelling model can be successfully exported to the wider creative ecosystem. For Netflix, the challenge remains to maintain the momentum of its decarbonization path while proving that sustainability is not just a corporate department, but a core component of its brand identity.
The story of climate change in film and television is still being written—and with Stewart’s new role, it is likely to become more prominent, more nuanced, and more essential than ever before.
