Netflix’s first chief sustainability officer steps down

Netflix sustainability chief departs after five years building climate program

Emma Stewart is leaving Netflix after nearly six years as the company’s first chief sustainability officer. She joined the streaming business in 2020 and built its climate program from the ground up. Now she’s moving to Climate Spring, a social enterprise focused on how film and television portray climate change.

The departure marks a significant shift for Netflix. Stewart led the company’s public climate strategy during a period when streaming businesses faced growing scrutiny over their environmental footprint. Her move also signals a wider trend: sustainability professionals are increasingly focusing on storytelling and cultural influence, not just operational carbon cuts.

For UK businesses watching how large corporations handle sustainability transitions, this change raises practical questions. What happens when a senior sustainability leader leaves? How do companies maintain momentum on climate commitments during leadership changes? Moreover, how important is continuity in a program that’s been presented as central to business operations?

Stewart’s new role suggests climate work is evolving. She will join Climate Spring’s leadership team and advise other organizations working at the intersection of climate and entertainment. The focus shifts from corporate decarbonization to audience engagement and how stories shape public understanding of climate issues.

Building Netflix’s climate strategy from 2020 onwards

Stewart arrived at Netflix in 2020 as its first chief sustainability officer. At that point, the company had no formal climate program. Her task was to establish one that could scale across a global business with operations in multiple countries and thousands of productions each year.

Netflix adopted what it called an “Optimize, Electrify, Decarbonize” approach. The strategy focused on three stages: reduce electricity consumption, switch to clean power sources, and address remaining emissions through lower-carbon alternatives. This framework shaped how the company tackled emissions across its offices, data centers, and production sets.

The company set a public target to cut emissions by roughly 46% by 2030 below 2019 levels. Third-party validators reviewed this goal, which aligns with broader corporate climate commitments. Netflix also stated it would match remaining emissions with investments in natural climate solutions, though details on these investments have been less specific in public reporting.

During Stewart’s tenure, Netflix reported several operational changes. Energy-efficiency audits became standard practice. The company committed to 100% clean energy programs where available in its markets. On the production side, pilot programs tested green hydrogen fuel cells and mobile battery systems as alternatives to diesel generators.

These measures produced measurable results, according to Netflix’s own reporting. The company stated it reduced its Scope 1 and 2 footprint by more than 10% from what it otherwise would have been in one year. Productions including Virgin River and Bridgerton used electric vehicles and battery or hydrogen power units, generating fuel savings and lower on-set emissions.

Production emissions account for majority of corporate footprint

Netflix’s ESG reporting identified production as the largest source of emissions across its business. Production-related emissions represent approximately 60% of the company’s total carbon footprint. This figure reflects the energy-intensive nature of film and television production, which typically relies on diesel generators for mobile power, transport fleets for crew and equipment, and energy use across multiple locations.

For context, this weighting differs from many other large corporations. In most businesses, operational emissions from offices and facilities dominate the footprint. However, Netflix’s model centers on content creation, which means production activity drives the majority of climate impact. Consequently, any serious emissions reduction strategy must address how films and series are made.

Netflix pursued several initiatives to tackle production emissions. Electric vehicles replaced diesel-powered transport where feasible. Clean mobile power units offered alternatives to traditional generators. Productions gained access to renewable energy sources when local grids or contracts made this possible. The company also worked with production partners to embed these practices into standard operating procedures.

Nevertheless, challenges remain. Production work often occurs in remote or temporary locations where clean energy infrastructure doesn’t exist. Equipment needs are highly variable, making it difficult to standardize solutions. Furthermore, productions involve multiple contractors and suppliers, which complicates oversight and accountability for emissions across the value chain.

The 60% figure also highlights a broader issue for UK businesses in creative industries. Film, television, advertising, and events all face similar production-related emissions challenges. Many SMEs in these sectors now encounter sustainability requirements in tender processes, client contracts, and broadcaster commissioning criteria. Therefore, how Netflix addresses production emissions offers a useful reference point for smaller businesses navigating the same territory.

What Netflix’s climate program achieved under Stewart’s leadership

Under Stewart’s leadership, Netflix established a structured climate program where none previously existed. The company moved from ad hoc environmental measures to a coordinated strategy with clear targets, reporting frameworks, and operational changes across its business units.

Key achievements include the validated 2030 emissions reduction target, which provides a public benchmark against which progress can be measured. The target’s third-party validation adds credibility, particularly as scrutiny of corporate climate claims intensifies. This matters for businesses of all sizes: credible, verified targets carry more weight than unverified statements of intent.

Netflix also developed specific interventions for its highest-impact area. By identifying production emissions as 60% of its footprint, the company focused resources where they would deliver the greatest effect. This prioritization reflects good climate strategy: address the biggest sources first rather than spreading effort thinly across minor contributions.

The pilot programs on productions demonstrated that alternatives to diesel generators and fossil-fuel transport can work in practice. While these remain pilots rather than universal standards, they provide evidence that change is technically feasible. This evidence matters for industry-wide adoption because it reduces the perceived risk of switching to new technologies or methods.

However, the program also faced limitations. Netflix’s reporting has been less transparent about Scope 3 emissions beyond production, such as supply chain impacts, employee commuting, and customer device energy use. Many large corporations struggle with Scope 3 measurement and reduction, but for a digital business with a global supply chain, these categories represent significant emissions that remain less visible in public reporting.

Additionally, the reliance on natural climate solutions to “match” remaining emissions raises questions. The effectiveness and permanence of these investments vary widely. Without detailed disclosure about which projects Netflix supports and how their carbon benefits are verified, it’s difficult to assess the true impact of this element of the strategy.

Leadership transitions and sustainability program continuity

Stewart’s departure creates a transition point for Netflix’s climate program. When a founding sustainability leader leaves, companies face the risk of losing institutional knowledge, momentum, and stakeholder confidence. This risk is particularly acute when the departing executive built the program from scratch and served as its public face.

For UK SMEs, this situation offers a useful lesson. Relying on a single individual for sustainability strategy creates vulnerability. If that person leaves, the program can stall or lose direction. Therefore, embedding sustainability into broader organizational structures, governance, and job descriptions reduces dependence on any one leader.

Netflix has not publicly announced Stewart’s replacement or outlined how it will maintain continuity. The company’s ESG materials continue to emphasize climate action, suggesting that sustainability work will proceed. However, the specifics of leadership structure, reporting lines, and strategic direction remain unclear from external reporting.

Businesses watching this transition should consider several questions. Will Netflix maintain the same level of ambition on production emissions? Will reporting transparency improve or contract under new leadership? How will the company handle accountability for its 2030 targets as it moves further from the baseline year? These questions apply to any business managing a sustainability program through personnel changes.

The move also reflects broader labor market trends in sustainability roles. Senior sustainability professionals increasingly have options beyond traditional corporate positions. Social enterprises, advocacy organizations, and storytelling initiatives now compete for talent with private-sector employers. Consequently, companies must think carefully about how they retain sustainability expertise and maintain program stability over time.

For businesses pursuing sustainability programs, building resilience into the structure matters. This means documenting processes, distributing responsibilities across teams, integrating sustainability into core business functions, and ensuring governance oversight at board level. These measures help programs survive leadership changes and continue delivering progress toward stated goals.

How climate work is expanding beyond operational emissions

Stewart’s move to Climate Spring illustrates a significant shift in sustainability work. Traditional corporate sustainability roles focus on measuring, reporting, and reducing a company’s direct environmental footprint. This work remains essential, but it represents only one dimension of how organizations influence climate outcomes.

Climate Spring’s focus on storytelling recognizes that film and television shape public understanding of climate issues. How these media portray climate change, solutions, and the transition to lower-carbon economies influences audience perceptions, political will, and behavior. Therefore, working on climate narratives in popular culture represents a different kind of climate intervention.

This expansion reflects a growing recognition that climate action requires cultural and social change alongside technical and operational measures. Businesses can reduce their own emissions, but broader climate goals depend on shifting consumption patterns, political support for climate policy, and public engagement with the issue. Storytelling and cultural production contribute to these shifts in ways that operational decarbonization cannot.

For UK businesses, this trend has practical implications. Sustainability is increasingly intersecting with communications, marketing, brand strategy, and stakeholder engagement. Companies that treat sustainability purely as a compliance or operations function may miss opportunities to influence wider outcomes through their communications, products, and services.

Moreover, businesses in creative industries face specific considerations. How they portray sustainability in their work, the narratives they choose to tell, and the values they embed in content all carry climate implications. Broadcasters, advertisers, publishers, and production companies can use their platforms to shape conversations about climate, nature, and sustainable development.

This broader view of climate work also creates new roles and career paths. Professionals with expertise in both sustainability and communications, storytelling, or audience engagement are increasingly valuable. Companies building sustainability teams should consider whether they need skills beyond environmental science, carbon accounting, and regulatory compliance.

Where to find further information on corporate climate programs

UK businesses looking for guidance on building sustainability programs can consult several authoritative resources. The UK government’s net zero strategy, available on the gov.uk website, outlines the national framework and policy context within which businesses operate. Additionally, the Department for Energy Security and Net Zero publishes sector-specific guidance and updates on climate policy.

The Environment Agency provides detailed emissions reporting guidance for businesses required to measure and disclose their carbon footprint. This resource covers Scope 1, 2, and 3 emissions methodologies and helps businesses understand regulatory requirements.

Industry bodies such as the Institute of Environmental Management and Assessment (IEMA) offer professional standards, training, and best practice guidance for sustainability practitioners. IEMA’s resources cover everything from carbon footprinting to stakeholder engagement and governance.

For businesses in the creative sector specifically, several organizations focus on sustainability in film, television, and media production. Albert, operated by BAFTA, provides carbon calculation tools and sustainability standards for the UK screen industry. Many broadcasters now require productions to meet Albert certification standards, making this a practical resource for production companies and related suppliers.

Finally, UK businesses pursuing science-based emissions targets can find methodologies and validation services through the Science Based Targets initiative. This organization provides frameworks for setting credible, verifiable climate targets aligned with limiting global temperature rise to 1.5°C above pre-industrial levels.
