Protecting Critical Infrastructure: Lessons from the CPC Drone Attack
The attack by naval drones on the infrastructure of the Caspian Pipeline Consortium (CPC) on 29 November was an alarming signal, not only for Kazakhstan but for the global energy sector. The temporary suspension of shipments and the shift to operating through a single remote mooring facility struck at the heart of Kazakhstan’s economy. Around 80% of Kazakhstan’s oil exports – generating roughly 40% of its export revenues – pass through the CPC, which has handled over 60 million tons of crude annually in recent years. The vulnerability of CPC infrastructure serves as a reminder of how tightly global energy security is intertwined with regional conflicts. The consortium not only carries Kazakh crude; it also plays a stabilizing role for several international stakeholders, including European refiners and multinational shareholders, such as Chevron and ExxonMobil. Any prolonged disruption would reverberate across global markets, raising transport premiums, tightening supplies in Southern Europe, and undermining confidence in the safety of trans-Eurasian energy routes. For a world already grappling with supply shocks, the Novorossiysk incident underscored how the effects from a single strike can ripple far beyond the immediate impact zone. At the same time, the incident revealed a broader and more urgent issue. Military operations are not supposed to target civilian infrastructure, particularly when it belongs to neutral third parties uninvolved in the conflict. While international humanitarian law (IHL) explicitly prohibits attacks on such facilities unless they are being used for military purposes, the reality on the ground is far less clear-cut. In contemporary conflicts, the line between civilian and military use can blur quickly, creating space for competing interpretations and contested justifications. The Legal Grey Zone of Modern Warfare Although the legal framework is clear on paper, its practical application has become increasingly strained in recent conflicts. The increasing use of drones, long-range precision munitions, and cyber tools has blurred the distinction between civilian and military infrastructure and has outpaced the mechanisms designed to protect them. Energy pipelines, ports, and terminal facilities - which once lay far from the frontlines - can now be struck at minimal cost and with limited attribution. This technological shift has opened a grey zone that existing IHL was never designed to manage, heightening the urgency for clearer norms and enforcement tools. The real challenge lies not in the absence of legal norms but in the lack of mechanisms to enforce them, particularly in cases where neutral countries’ assets become collateral damage. There is, therefore, an argument for the introduction of a new international legal framework – or supplementing existing provisions via a UN protocol – to safeguard critical infrastructure. This is especially relevant in an era of precision weapons and drone warfare, where pipelines, energy terminals, and logistics hubs increasingly fall within potential strike zones. Yet the implementation of such a framework faces complications. Under existing IHL, dual-use infrastructure, such as pipelines that may carry resources for both civilian and military use, can be deemed legitimate military targets. Ukrainian officials have justified strikes on Russian energy...
