An organisation can optimise what it owns and still worsen the system in which its strategy must succeed.
Most management systems are built around boundaries.
A company has legal entities. A business unit has a budget. A project has a scope. A plant has a fence line. A government agency has a jurisdiction. Performance is measured within those lines because accountability requires some definition of control.
Externalities ignore them.
Pollution can move across regions. Supplier decisions can shift environmental burden upstream. Health effects can appear far from the activity that contributed to them. Capital inflows can improve one local economy while creating pressures that appear in a neighbouring area.
The strategic challenge is not to eliminate boundaries. It is to stop confusing administrative boundaries with system boundaries.
The Strategic Context
Two 2017 studies using Chinese data provide different views of this problem.
Lu and colleagues investigated the dynamic relationship between environmental pollution, economic development and public health using provincial panel data from 2002 to 2014. Their simultaneous-equation model considered sulphur dioxide, wastewater, soot and dust indicators alongside economic and health variables. The study found a negative relationship between pollution and public-health outcomes while also showing that economic and social factors such as income, education and medical conditions were part of the wider system.
Zhu, Gan, Liu and Yan examined foreign direct investment and sulphur-dioxide emissions across ten cities in the Beijing-Tianjin-Hebei region using data from 2000 to 2013. Their spatial analysis found that local emissions were associated not only with local FDI but also with activity in surrounding areas.
These are historical, context-specific econometric studies, not universal laws. Their value for executives lies in what they expose: effects propagate.
A decision can create consequences outside the unit that made it, outside the geography where the activity occurs and outside the period in which performance is reported.

What Leaders Commonly Misread
The first misread is that outsourcing transfers responsibility because it transfers activity.
A manufacturer may reduce direct emissions by purchasing a previously internal component. The enterprise has changed its operating boundary. The atmosphere has not necessarily experienced an equivalent improvement.
The second is that local optimisation will aggregate into system optimisation. A city can attract investment, a plant can increase output and a supplier can reduce cost, yet the combined system may experience congestion, pollution, resource stress or public-health effects that none of the individual scorecards capture.
The third is to treat externalities only as ethical issues. They are also economic and strategic. External effects can return through regulation, insurance, litigation, community opposition, labour availability, infrastructure constraints, customer behaviour or financing conditions.
The fourth is to believe that if a consequence is difficult to attribute precisely, it should remain outside the decision. Uncertainty should affect confidence, not justify blindness.
Reframing the Issue
Leaders need two boundaries for major decisions.
The first is the accountability boundary: the assets, people and transactions directly controlled by the organisation.
The second is the consequence boundary: the wider system in which material effects can emerge.
Those boundaries will rarely be identical.
A consequence boundary may include suppliers, customers, surrounding communities, shared infrastructure, regional ecosystems, public-health systems and future asset owners. It does not mean the organisation is solely responsible for every effect. It means leaders understand where strategy interacts with conditions outside direct control.
This distinction is essential for systems thinking. Responsibility can be shared while consequences remain real.

Economic Growth and Environmental Quality Are Interdependent
The public-health study is strategically useful because it resists a one-variable story.
Economic development can improve health through income, education, infrastructure and medical capability. Economic activity can also create pollution that damages health. The net outcome depends on pathways, institutional capacity, technology and distribution.
That means "growth versus environment" is often a poor executive frame.
The better question is which growth model produces the desired economic benefits with acceptable environmental and health consequences.
For a company, the equivalent question may be whether expansion increases value without creating resource, workforce, community or regulatory conditions that undermine the same growth.
For government, the question may concern where development occurs, which infrastructure precedes it and how cross-jurisdiction effects are governed.
The system contains feedback loops. Ignoring them can make a strategy self-defeating.
Spatial Spillovers Change the Unit of Governance
The FDI study's spatial finding raises a particularly important point: geography matters.
If economic activity in one area affects environmental conditions in another, city-by-city governance can be structurally incomplete. The same is true for watersheds, transport corridors, electricity networks and supply clusters.
Organisations face analogous problems.
A procurement team can choose a lower-cost supplier without seeing the infrastructure or environmental load concentrated in the supplier region. A business unit can move production to another plant and report improved local efficiency while the network becomes less resilient. A logistics optimisation can reduce one site's cost while increasing congestion or delivery risk elsewhere.
When effects propagate across nodes, governance must follow the network rather than the organisation chart.
Transfer Is Not Reduction
One of the most important tests in sustainability strategy is whether an improvement represents a genuine system reduction or a transfer.
Burden can be transferred across four dimensions.
It can move organisationally, from internal operations to suppliers.
It can move geographically, from one region to another.
It can move temporally, from current performance to future liabilities.
It can move between impact categories, such as reducing carbon while increasing water stress or toxic exposure.
A local dashboard may record success in every case. Only a wider system view reveals whether value was created.
Externalities Belong in Capital Allocation
Externalities are often considered after an investment has been selected, through environmental approvals, community consultation or compliance reviews.
That sequencing is too late when the external effect could change the strategic option.
A site with lower land cost may impose much higher transport demand. A process with cheaper energy may rely on a water-intensive cooling system in a constrained region. An offshore supplier may reduce direct cost while adding geopolitical or environmental exposure.
These are not secondary implementation details. They are option characteristics.
Capital allocation should therefore ask which external conditions the investment depends on and which external effects it creates.
The organisation does not need to monetise every consequence. It does need to identify material consequences early enough to change the decision.

Distribution Matters as Much as the Average
Externalities are rarely distributed evenly.
An investment can create positive aggregate value while concentrating environmental or health costs in a small community. A regional policy can improve average air quality while leaving a high-exposure corridor unchanged. A supply-chain redesign can lower enterprise emissions while increasing local water stress around one supplier cluster.
Average performance can therefore conceal strategic fragility.
Distribution matters because concentrated consequences often determine stakeholder response, regulatory attention and social licence. The organisation should know not only the total effect, but who experiences it, where and for how long.
This is especially important for portfolio decisions. Several individually modest projects can accumulate around the same geography, infrastructure corridor or community. The portfolio can create a concentration risk that no project business case sees.
A consequence map should therefore aggregate exposures across initiatives, not merely evaluate each project independently. That is where portfolio governance adds information that project governance cannot.
Decision Framework
A cross-boundary decision can be tested through six lenses.
Source: What activity, investment or operating choice creates the effect?
Pathway: Through what physical, economic or behavioural mechanism can the effect travel?
Receptor: Which communities, assets, ecosystems, customers or public systems may experience the consequence?
Distribution: Are costs and benefits concentrated in different groups, geographies or time periods?
Governance: Which actors have authority over the source, pathway and receptor, and where are coordination gaps?
Feedback: How could the external consequence return to affect enterprise value through regulation, reputation, cost, resilience or market behaviour?
This framework helps leaders distinguish direct control from strategic exposure.
From Strategy to Execution
The immediate step is to select one major investment or operating decision and draw its consequence map beyond the legal entity. Include material supplier, customer, infrastructure, community and environmental interfaces. The purpose is not to produce a perfect lifecycle study; it is to find effects large enough to alter the decision.
Next, identify transfers. If a KPI improves, ask where the underlying burden went. A reduction should be distinguishable from relocation.
Medium term, portfolio governance should incorporate cross-boundary criteria before approval. High-consequence programmes may require regional, supply-chain or lifecycle analysis rather than site-only analysis.
Where multiple organisations share a system, create explicit coordination mechanisms. Joint monitoring, common thresholds, data sharing and escalation arrangements can sometimes manage a problem that no single actor can control.
Long term, organisations should treat externality management as strategic sensing. Changes in public health evidence, regulation, infrastructure capacity, community expectations and environmental constraints can alter the economics of established assets.
A boundary that was once adequate for management may become too narrow for strategy.
Foresight: Externalities Can Become Internal Faster Than Expected
An external cost remains external only while the enterprise is not required to absorb it.
Policy can change that through taxes, standards, disclosure, liability or permitting. Markets can change it through customer requirements, investor preferences, financing conditions or insurance. Physical scarcity can change it through higher input costs and disrupted operations.
This means externality analysis is partly a foresight discipline.
Leaders should ask which currently unpriced consequences are most likely to become priced, constrained or publicly visible within the life of the asset.
The answer will differ by industry, geography and investment horizon. A short-lived service decision and a forty-year infrastructure asset should not use the same foresight boundary.
Shared Systems Need Shared Escalation
Cross-boundary problems also require a clear escalation path. When no single organisation controls the whole causal chain, issues can circulate between owners without resolution. A practical governance response is to define the conditions under which a local issue becomes a network or regional issue, who convenes the affected parties and what evidence is required for joint action.
This prevents shared responsibility from becoming diluted responsibility. Collaboration is most useful when decision rights, thresholds and unresolved-accountability gaps are explicit.
Signals to Monitor
Watch for divergence between local performance and regional conditions. A site may be improving while surrounding water, air, congestion or community indicators deteriorate.
Monitor supplier and customer concentration in environmentally constrained regions. Geographic exposure can accumulate silently even when procurement is diversified by company name.
Track policy discussion around costs the organisation currently does not bear directly. The period between public concern and formal regulation can be a valuable window for adaptation.
Also watch for recurring stakeholder issues that sit outside existing ownership. If complaints repeatedly move between agencies, suppliers or business units, the problem may be falling into a governance gap.
Questions for the Leadership Team
- Which material consequences of our strategy occur outside the boundaries of our own assets and legal entities?
- Where could we be transferring burden rather than reducing it?
- Which external effects could return as future cost, constraint or loss of legitimacy?
- Are any of our major investments dependent on environmental or social conditions that no one inside the organisation owns?
- Where do regional or supply-chain effects require governance across organisational boundaries?
- Which currently unpriced externality is most likely to become decision-relevant during the life of our assets?
- What would change if we evaluated the system in which we operate rather than only the unit we control?
Closing Perspective
Boundaries are necessary for accountability. They are dangerous when they become boundaries of thought.
The enterprise does not operate in isolation from public health, regional infrastructure, supplier ecosystems, environmental capacity or neighbouring economies. Strategy can change those systems, and those systems can change the value of strategy.
Leaders therefore need the discipline to manage what they control while understanding what their decisions influence.
Externalities are not somebody else's problem simply because they appear somewhere else. They are signals that the real system is larger than the management boundary, and that durable value depends on seeing enough of that system before committing to the choice.
