Inside the Struggle to Enforce Environmental Laws Across Borders

Pollution does not need a passport.

A shipment of hazardous waste can leave one country, pass through several others and arrive at a port thousands of kilometres away. Timber can be illegally harvested in one jurisdiction, processed in another and sold in a third. Wildlife can be poached in one country, transported through neighbouring states and purchased by consumers on another continent. Illegal mining can contaminate a river that crosses an international boundary, leaving communities downstream to deal with damage caused partly outside their own jurisdiction.

Environmental systems are interconnected in ways that national legal systems often are not.

That is the central problem behind one of the most difficult questions in environmental governance: how do you enforce environmental laws when the environmental harm, the people responsible, the companies involved and the evidence needed to prosecute them may all exist in different countries?

International environmental agreements have created important rules for dealing with these problems. The Basel Convention, for example, establishes controls for the transboundary movement of hazardous and other wastes and requires parties to prevent and punish illegal traffic. Yet the existence of an international agreement does not automatically translate into effective enforcement at a port, border crossing, mine, forest or courtroom.

The gap between international commitments and enforcement on the ground is where much of the struggle begins.

Environmental crime rarely respects national boundaries

Environmental crime is broader than illegal dumping or poaching. INTERPOL identifies major areas including wildlife crime, pollution crime, fisheries-related crime, forestry crime and illegal mining. These activities increasingly involve networks that operate across multiple countries and can be connected to corruption, fraud, money laundering and other forms of organized crime.

This creates a fundamental enforcement problem.

Imagine a company registered in Country A purchasing minerals extracted illegally in Country B, moving them through Country C and selling the finished product in Country D. Investigators in Country B may have evidence of the illegal extraction, while customs authorities in Country C may have information about the shipment. Financial records may sit in Country A, and the final buyer may be located in Country D.

The environmental offence is therefore not necessarily confined to one place.

But national authorities generally derive their investigative and prosecutorial powers from national law. A regulator in one country cannot simply cross a border and seize evidence, inspect a foreign facility or arrest a suspect without the appropriate legal authority and cooperation.

The environmental damage may be transboundary. The enforcement powers are not.

That mismatch creates opportunities for offenders to exploit gaps between jurisdictions.

The jurisdiction problem

Jurisdiction is one of the most basic obstacles to cross-border environmental enforcement.

Every country has sovereignty over its territory, and environmental legislation is primarily implemented through national institutions. When an offence involves several countries, authorities must determine which country has jurisdiction over which part of the conduct.

This becomes particularly complicated when environmental offences involve international supply chains.

A timber shipment may be illegally harvested in one country, transported through another and exported by a company incorporated elsewhere. A waste shipment may originate with a producer in one jurisdiction, be transported by an international logistics company and arrive at a facility in another.

Who investigates the original offence?

Who investigates the transport?

Who prosecutes the company?

Who is responsible for returning or properly disposing of the material?

These questions cannot always be answered by one country's environmental law.

International agreements can establish common obligations and procedures, but their implementation still depends heavily on national legislation, competent authorities and cooperation between governments.

The Basel Convention illustrates both the importance and complexity of this system. Its rules require notification and, where applicable, prior written consent for certain transboundary movements of waste. It also establishes provisions addressing illegal traffic and responsibilities when such movements occur.

The challenge is making those rules work consistently across the entire chain.

Different laws create different enforcement gaps

Countries do not necessarily define, regulate or punish environmental offences in the same way.

One jurisdiction may impose strict controls on a particular waste stream while another has weaker requirements. One country may criminalize conduct that is treated as an administrative violation somewhere else. Penalties, evidentiary requirements, regulatory capacity and investigative powers can also differ substantially.

These differences matter because environmental criminals do not necessarily operate within the boundaries of the strongest regulatory system.

They can search for weaknesses.

This does not mean that every country with weaker environmental regulation is deliberately creating a "pollution haven." The reality is more complicated. Governments may face competing economic priorities, limited technical capacity, inadequate monitoring infrastructure or difficulties implementing legislation that already exists.

But from an enforcement perspective, the result can still be similar: activities that are heavily controlled in one jurisdiction may be easier to conceal or conduct in another.

The problem becomes especially serious when enforcement agencies do not have timely access to information from their counterparts across the border.

Waste is a clear example

The international movement of waste demonstrates why environmental enforcement cannot stop at national borders.

The Basel Convention was created to control the transboundary movement of hazardous wastes and their disposal. Its framework requires parties to minimize such movements and ensure that permitted movements are conducted in ways that protect human health and the environment.

Electronic waste presents a particularly complicated challenge because equipment can move through legitimate international trade channels while the distinction between a functioning used product and waste can become important for enforcement.

The Basel Convention's e-waste amendments significantly changed the control regime. Adopted in 2022, the amendments expanded controls so
