Wildlife and environmental crimes, like most crimes, are motivated by money Almost all will involve a transaction or purchase before, during or after the crime even if it is not directly related to the commission of the crime. These transactions leave an indelible record in financial systems that investigators can use. Financial investigation can be used to provide intelligence and evidence of criminality such as identity, properties, vehicles, lifestyle and movements of offenders, co-conspirators, and victims. It can also support seizure and confiscation of assets acquired through crime, with a view to returning the proceeds to victims or confiscating assets so that they can no longer benefit the offender. Money laundering is the process of disguising the origin or source of illegally gained financial assets so they can be used without detecting the illegal activity that produced them; i.e. the criminal transforms the monetary proceeds derived from criminal activity into funds that appear to have been legally acquired. To place, layer, and integrate the proceeds of these environmental crimes into the legitimate financial system, criminals exploit vulnerabilities. The Philippine government enacted legislation in 2013 that made environmental crimes predicate offences for money laundering. A predicate offence is a crime that acts as a trigger to enable the use of anti-money laundering legislation. At the time of publication, there has still not been a successful money laundering conviction in the Philippines for crimes predicated on breaking environmental laws. Similarly, few environmental cases have been investigated, yet the threat posed by these crimes is rated "high" in the Philippine National Money Laundering and Terrorist Financing (ML/TF) Risk Assessment which considers the impact of these violations to the environment and the people. It is recognised that the limited understanding of Philippine anti-money laundering regulations and possible pathways of leveraging financial investigation to complement standard law enforcement poses challenges. These guidelines aims to encourage and support the use of follow-the-money principles and anti-money laundering legislation by wildlife and environmental enforcement officers by providing a practical review of the Philippine legal framework relating to antimoney laundering (AML) applied to environmental crimes and providing practical guidance on its application. It also seeks to increase synergy and cooperation among government agencies in charge of enforcing environmental laws and anti-money laundering regulations.
