Conflict and Sustainability: How Conflict Reshapes the Environmental Risk Landscape

Conflict is usually analysed through geopolitics, energy markets or humanitarian impact. But war also changes the environmental pressures that economies and supply chains must operate within.

The current conflict involving Iran shows how quickly this can happen. Strikes on oil infrastructure have raised concerns about pollution and ecological damage. Burning facilities can release contaminants into surrounding ecosystems. Experts have warned that damaged pipelines and refineries could leave a toxic legacy affecting land, water and public health long after the conflict ends.

Those risks are immediate.

But the more important shift lies in how conflict interacts with environmental pressures that already exist. When a geopolitical shock hits an already strained energy and environmental landscape, it can change the direction of sustainability policy, investment and regulation.

That shift matters for governments, communities and the supply chains that sit at the centre of the global economy.

Sustainability as a Structural Pressure

Environmental pressure has been building for decades. Climate change, ecosystem degradation and the transition away from fossil fuels are not abstract policy debates. They shape energy prices, industrial investment and the regulatory environment companies operate in.

These pressures act as structural stresses.

A stress builds slowly over time. Rising energy demand, climate policy and environmental degradation all increase pressure on how economies produce and move goods.

A trigger is different. It is a sudden event that changes how those pressures evolve.

Conflict is one of the most powerful triggers that can enter the sustainability landscape. Environmental pressures do not disappear during war. Instead, conflict interacts with them and often pushes them in new directions.

Understanding that interaction is essential for understanding the risks that follow.

Energy Security vs Energy Transition

One of the most immediate effects of conflict is pressure on energy supply.

When oil or gas infrastructure is threatened, governments prioritise stability. Energy supply must continue, prices must remain manageable and industrial activity must keep functioning.

In those moments, the long-term transition away from fossil fuels can slow.

Governments may extend the life of existing oil and gas assets, increase domestic production or delay environmental regulation to stabilise supply. The UN climate chief recently described the Iran conflict as an “abject lesson” in how dependent the global economy still is on fossil fuels.

Security shocks expose the structure of the energy system. But conflict can also accelerate change. Geopolitical risk encourages governments and companies to diversify energy sources, invest in renewables or reduce dependence on vulnerable supply routes.

The result is a tension that often defines sustainability policy during crises. Conflict can produce both reversals and accelerations in the energy transition.

Environmental Damage Creates Long-Term Risk

Conflict also generates environmental damage that can persist for decades.

Strikes on oil infrastructure release pollutants into air, soil and water. Oil fires and damaged pipelines contaminate surrounding ecosystems. Researchers have warned that attacks on Iranian energy facilities could produce environmental fallout that spreads beyond the immediate conflict zone.

Environmental damage rarely remains local.

Pollution travels through air and water systems. Contaminated land can reduce agricultural productivity for years. Toxic exposure can create long-term health risks for communities living near affected areas.

These consequences do not end when fighting stops. They become new environmental pressures that governments, industries and communities must manage long after the conflict itself fades.

Fragmentation of Sustainability Governance

Conflict also changes the political environment in which environmental policy is made.

Periods of geopolitical tension weaken international cooperation. Governments focus on national security, industrial resilience and strategic competition. Sanctions reshape trade flows and supply chains. Coordinated environmental policy becomes harder to maintain.

The result is a more fragmented sustainability agenda.

Some countries prioritise energy security and domestic fossil fuel production. Others accelerate investment in renewable energy to reduce strategic vulnerability. Regulatory approaches diverge as governments balance economic stability, security and environmental commitments.

For businesses operating across multiple markets, this fragmentation creates a more complex regulatory landscape. Environmental policy becomes increasingly shaped by geopolitics.

What This Means for Supply Chains

Supply chains operate directly inside this changing environment.

Energy price volatility affects production costs and transport networks. Environmental damage can disrupt infrastructure, natural resources and logistics routes. Regulatory shifts alter compliance requirements and investment decisions.

Supply chains also transmit these pressures through the wider economy. Higher energy costs feed into production prices. Resource disruptions reshape manufacturing decisions. Infrastructure damage alters trade routes and logistics planning.

In that sense supply chains are both victims and carriers of environmental disruption.

Understanding how environmental pressures evolve during conflict is therefore not just a sustainability issue. It is a strategic challenge for companies that depend on global production and transport networks.

Conflict Redirects the Sustainability Agenda

The key point is simple.

Conflict does not pause sustainability pressures. It redirects them.

Some environmental trajectories slow as governments prioritise energy security. Others accelerate as geopolitical risk pushes investment toward new energy systems or exposes the environmental costs of conflict itself.

For policymakers and businesses alike, sustainability cannot be treated as a separate agenda from geopolitics or economic risk.

They are deeply intertwined.

And in a world shaped by conflict and systemic shocks, the environmental pressures facing supply chains will continue to evolve alongside the geopolitical forces reshaping the global economy.
