Net Zero Is Not the Whole Story.
The Atmosphere Does Not Negotiate with Narratives.

The atmosphere does not negotiate with narratives. Carbon accumulates according to physics, not corporate baselines. Yet much of today’s climate discourse is built around precisely that — narratives of progress measured against internal baselines, operational boundaries, and accounting conventions that bear little resemblance to the physical system they are meant to stabilize.

Organizations declare net zero targets. Roadmaps are published. Progress charts show declining emissions against a baseline year, often somewhere around 2015. Operational emissions fall. Purchased energy becomes cleaner. Sustainability reports describe steady movement toward long-term climate commitments. Inside the organization, the story feels responsible. Outside the organization, the climate system continues to move in the opposite direction.

In systems terms, this is reductionism. Reductionism occurs when improvement in one part of a system is mistaken for improvement of the system itself. It allows institutions to focus on what they directly control while treating the rest of the system as external context. That pattern is visible in the way corporate emissions are measured.

The Scope Problem

Under the accounting structure established by the Greenhouse Gas Protocol, emissions are divided into three scopes. Scope 1 covers direct emissions from an organization’s operations. Scope 2 includes emissions associated with purchased energy. Scope 3 encompasses the wider value chain: suppliers, logistics, product use, and end-of-life impacts.

When organizations pursue net zero strategies that focus primarily on Scopes 1 and 2 while leaving Scope 3 largely outside the operational boundary, they are not solving the system. They are narrowing the frame of measurement until success becomes possible. Data collected by CDP, a global environmental disclosure system used by thousands of companies and investors, shows that Scope 3 emissions account for roughly three quarters of total emissions on average across reporting companies. A strategy focused primarily on Scopes 1 and 2 addresses only a minority of the problem.

Part of the justification is familiar. Leaders argue that most Scope 3 emissions occur outside the organization’s direct control — in supplier operations, logistics networks, product use, and disposal. But absence of control does not mean absence of influence. Organizations shape their value chains through purchasing power, contract terms, capital investment, and product design. Influence exists. It requires investment.

The Planetary Boundary the Baseline Ignores

Researchers at the Stockholm Resilience Centre describe climate stability as one of several limits within the Planetary Boundaries Framework that define the safe operating space for human activity. Their work suggests that atmospheric carbon dioxide concentrations above roughly 350 parts per million represent a departure from that safe zone. That threshold was crossed decades ago. Today atmospheric concentrations exceed 420 parts per million.

This changes the baseline for what progress means. If the system is already outside the safe operating space, measuring improvement relative to recent corporate baselines does not tell us whether we are moving back inside that space. It only tells us whether the rate of overshoot has slowed. Reducing harm is not the same as restoring stability.

This distinction is central to what sustainability practitioners increasingly describe as context-based sustainability. Performance must ultimately be measured against the carrying capacity of the system being affected rather than merely against an organization’s historical performance.

Measurement Is Necessary. It Is Not Sufficient.

None of this means measurement or reporting should be dismissed. Measurement is essential. Without it there is no accountability. Organizations must quantify their impacts, disclose them transparently, and track progress over time. At GPM we do exactly that — publishing annual emissions reporting and measuring our own footprint using the same frameworks we advocate for others. We are also close to fully quantifying our Scope 3 emissions. That work matters because measurement exposes the real boundary of the system. It shows where influence exists and where investment must follow.

But measurement alone does not change the outcome. Our own goal is not simply net zero. It is net positive. The objective is to contribute more to the systems that sustain life than we extract from them. That standard forces a different set of decisions. It requires looking beyond operational emissions and into the structure of the systems we participate in. It requires asking whether our work restores capacity or simply slows decline.

Organizations can produce detailed sustainability disclosures while continuing to invest in infrastructure, supply chains, and products that lock in emissions for decades. When reporting is connected to intervention it strengthens governance. When reporting substitutes for intervention it becomes narrative management.

The Integrity Threshold

This is where the concept of an integrity threshold becomes useful. An integrity threshold is the point where what an institution claims and what its system produces begin to diverge in structural ways. Leaders describe progress while the underlying system continues to generate outcomes inconsistent with those claims. Net zero commitments often sit precisely on that line.

Organizations say they are pursuing decarbonization while continuing to expand production systems that depend on fossil energy. Emissions decline within operational boundaries while the wider system producing the majority of emissions remains unchanged. Reports describe responsible action while atmospheric concentrations continue rising. Where that gap exists, sustainability becomes theater. The emissions will enter the atmosphere whether the report calls them progress or not.

None of this means net zero targets should be abandoned. Reducing emissions matters. Efficiency improvements matter. Renewable energy matters. These actions are necessary steps in a broader transition. The problem is treating them as the whole solution when they represent only part of the system. A transition that addresses only the emissions an organization directly controls while leaving the wider economic system unchanged cannot deliver climate stability on its own.

The question therefore is not whether organizations should pursue net zero commitments. The question is whether net zero, as it is currently practiced, represents genuine system change or simply a more sophisticated form of reductionism. If the strategy works only when the boundary is kept small, the system has not changed. Only the story has.
