Many environmental agencies play important roles in reducing environmental damage and protecting the environment through environmental laws and regulations. These agencies operate at varying levels from International, Regional, National, State to Local level, keeping one agency working at one level. Various enforcement methods are employed by these agencies to warrant compliance with environmental laws and regulations. In some case’s enforcement agencies use what is called “Command and Control” which are traditional regulatory approaches. In other cases, they may use economic incentive and hybrid-based approaches, which there are two. Moreover, it has increased the need for cooperation between different policing institutions. Environmental law enforcement agencies and police services do not operate in a vacuum; the legislative instruments that political systems implement govern their activities and responsibilities within society. However, ostensibly it is the legislative instruments implemented by governments that determine many of the strategies utilised by police services in protecting the environment. Generally these International, Regional, National and State legislative instruments are designed to ensure industries, individuals, and governments comply with the various environmental obligations embedded in national statutes and laws. There are also international legal instruments and treaties that also affect the way that sovereign states deal with environmental issues .
