Scope 4 Emissions: The Avoided Emissions Every Business Should Report

Scope 4 emissions, also referred to as avoided emissions, represent one of the most forward-looking concepts in modern carbon accounting. Rather than measuring what a company emits, this category captures the greenhouse gas reductions that occur when a business’s products or services replace more carbon-intensive alternatives. As pressure on corporate climate strategies intensifies, understanding and reporting scope 4 emissions offers organisations a more complete picture of their environmental impact, one that encompasses both the costs and the contributions of their activities.

What Are Scope 4 Emissions?

Scope 4 emissions are defined as greenhouse gas reductions occurring outside a product’s lifecycle or value chain, directly resulting from the use of that product or service ^[1]. The concept was introduced by the World Resources Institute in 2013 and progressively formalised by the GHG Protocol, which published a guidance framework to help businesses estimate and report avoided emissions, while making clear that this category remains distinct from official Scope 1, 2 and 3 reporting ^[1].

Unlike traditional emissions accounting, scope 4 does not measure what a company releases into the atmosphere. It measures what others avoid emitting because of that company’s solution. A videoconferencing platform, for instance, generates avoided emissions when it substitutes for long-haul business travel. A low-temperature detergent generates avoided emissions by reducing the energy consumed in every household wash cycle compared to a standard alternative.

The GHG Protocol is explicit on one critical point: avoided emissions must not be used to offset or adjust a company’s Scope 1, 2 or 3 inventory figures ^[2]. They are calculated separately and serve a distinct communicative purpose, illustrating the positive climate contribution of a product or technology rather than reducing the reported footprint of its producer.

Three broad categories of avoided emissions are generally recognised by practitioners ^[3]: replacing a carbon-intensive solution with a lower-emission alternative; reducing emissions through investment in low-carbon infrastructure; and financing sustainable projects that generate measurable emissions reductions in connected systems.

Scope 4 vs. Scopes 1, 2 and 3: Key Differences

To understand why scope 4 emissions matter, it helps to situate them within the broader emissions reporting landscape. The GHG Protocol’s three established scopes each capture a different layer of a company’s carbon impact, as illustrated in the table below.

The key structural difference is directionality. Scopes 1, 2 and 3 are, by definition, emission sources. Scope 4 is an emission sink, a category that attempts to credit companies for the positive climate impact of their solutions in the broader economy ^[4].

Scopes 1, 2 and 3 are mandatory or strongly recommended under frameworks such as the Corporate Sustainability Reporting Directive (CSRD) and the GHG Protocol’s Corporate Standard. Scope 4, by contrast, remains entirely voluntary and lacks a universally accepted calculation standard ^[5]. Businesses that choose to report avoided emissions do so as part of a broader commitment to transparency, not because they are legally required to do so.

For a detailed overview of how Scopes 1, 2 and 3 apply specifically to audiovisual productions, TheGreenshot’s guide to emission scopes in audiovisual production provides sector-specific breakdowns of each category.

How to Calculate Avoided Emissions

Calculating scope 4 emissions follows a consistent comparative logic: measure the emissions profile of a product or service against a reference scenario where that product does not exist. The difference between the two represents the avoided amount. The GHG Protocol guidance recommends a three-stage approach ^[1].

The first stage is defining the reference scenario: the conventional product, behaviour or technology that the company’s solution replaces. This baseline must reflect a realistic market alternative, not an extreme worst-case comparator. An energy-efficient LED lighting system, for example, should be benchmarked against the standard halogen or fluorescent technology it displaces in the relevant market, not against the least efficient equipment theoretically available.

The second stage involves measuring the full lifecycle emissions of the reference scenario, using verifiable and traceable data sources. Institutional databases such as those maintained by ADEME, the International Energy Agency (IEA) or sector-specific bodies can provide credible emission factors for common reference technologies.

The third stage is to subtract the emissions generated by the low-carbon solution from the reference scenario total. The resulting figure represents the emissions avoided, expressed in tonnes of CO2 equivalent.

The primary methodological challenge lies in constructing a credible and transparent reference scenario ^[6]. Two companies offering comparable solutions may arrive at substantially different scope 4 figures depending on baseline choices. This inconsistency remains one of the main barriers to widespread adoption and is precisely why the GHG Protocol emphasises rigour, transparency and full disclosure of methodology. For teams managing carbon reporting across multiple productions, GreenPro from TheGreenshot provides structured carbon accounting aligned with GHG Protocol standards, offering the operational data foundation needed to construct defensible avoided emissions estimates.

Why Scope 4 Reporting Matters for Businesses

Though voluntary, reporting avoided emissions is gaining momentum among sustainability-forward organisations for several converging reasons.

Investor and stakeholder expectations

Institutional investors and ESG rating agencies are increasingly looking beyond mandatory disclosures. Companies able to demonstrate a positive climate contribution through avoided emissions signal long-term strategic alignment with net-zero objectives ^[4]. For technology providers, software vendors and sustainable solution manufacturers, this is a substantive differentiator in capital markets conversations.

Competitive differentiation through climate contribution

For businesses whose products or services are specifically designed to reduce environmental impact, scope 4 reporting transforms a product catalogue into a climate narrative. It allows organisations to quantify the systemic value of their offerings beyond their own operational footprint, communicating not just “how much we emit” but “how much we help others to avoid emitting.”

Evolving voluntary reporting frameworks

The European Union has proposed voluntary reporting standards (VSME) designed to complement the CSRD for smaller entities not covered by mandatory obligations ^[7]. As these frameworks mature and consolidate, avoided emissions are expected to gain more formal recognition within broader sustainability disclosures.

Greenwashing risk management through rigour

Paradoxically, rigorous scope 4 reporting reduces greenwashing risk. By applying verifiable methodologies, selecting conservative baselines and disclosing all assumptions publicly, companies protect themselves from accusations of inflating environmental credentials ^[6]. The reputational and legal exposure associated with unsubstantiated environmental claims makes methodological transparency a business imperative, not merely an ethical preference.

For a broader perspective on how carbon measurement tools support corporate climate reporting, TheGreenshot’s overview of carbon calculators in the audiovisual sector provides a useful comparative framework.

Scope 4 Emissions in Audiovisual and Event Productions

The media and entertainment (M&E) sector presents specific and significant opportunities for avoided emissions reporting, both for production companies and for the clients who commission content. The sector’s operational model, characterised by high-intensity logistics, frequent travel and energy-dense technical infrastructure, makes it a natural context for comparing conventional practices against lower-carbon alternatives.

Film and television productions

Audiovisual productions generate emissions across the full Scope 1, 2 and 3 spectrum, from generator fuel on location to crew travel and catering supply chains ^[8]. Scope 4 enters the picture when productions adopt solutions that enable measurably lower-carbon alternatives to conventional workflows.

A production switching from physical location scouts requiring intercontinental travel to remote scouting technology generates quantifiable avoided emissions. The reference scenario (flights, accommodation and ground transport for in-person scouts) can be estimated using established emission factors, and the difference against the digital alternative produces a credible avoided emissions figure. Similarly, a production house deploying virtual production techniques, replacing practical exterior builds with LED volume stages, eliminates a category of logistics emissions that would otherwise occur in the conventional approach.

Organisations such as Albert and Ecoprod have developed sector-specific carbon accounting methodologies that can serve as reference frameworks for these comparisons, providing the standardised baselines that defensible scope 4 calculations require.

Events and live productions

For event producers, the avoided emissions calculation is equally tractable. A hybrid conference replacing a fully in-person format can estimate the emissions avoided from flights and accommodation not taken by remote attendees, benchmarked against the equivalent in-person event. Festivals deploying solar-powered infrastructure in place of diesel generator banks generate avoided emissions relative to a conventional energy baseline, a comparison that can be quantified using published emission factors for generator fuel consumption.

These calculations require rigorous documentation of both the intervention and the counterfactual. Production teams need reliable baseline data on conventional practices, and operational data on the solutions deployed, to produce credible scope 4 figures.

Conclusion

Scope 4 emissions offer businesses a way to articulate not just their environmental costs, but their environmental contributions. By quantifying the emissions avoided through their products and services, organisations can tell a more complete climate story, one that resonates with investors, clients and regulators alike.

The methodology is demanding, the risk of greenwashing is real, and universal standards remain in development. But for companies committed to rigorous transparency, particularly in sectors such as audiovisual production and live events where avoided emissions from remote workflows and sustainable infrastructure are increasingly significant, scope 4 reporting represents both a strategic differentiator and a meaningful contribution to systemic decarbonisation.

As avoided emissions frameworks mature and voluntary reporting standards consolidate, the question for organisations is no longer whether to measure their scope 4 impact, but how to do so with the rigour and transparency that gives the figure genuine credibility in the eyes of stakeholders and regulators.
