The DOE functions with full autonomy to enforce the Environmental Protection Act which grants broad regulatory and enforcement authority for the prevention and control of environmental pollution, conservation and management of natural resources.
In order to fulfill its obligations, the DOE has divided its responsibilities into three major public services, namely the Issuance of Licenses and Permits, Screening for Environmental Clearance and Access to Information.
In order to monitor and regulate pollution and other outstanding environmental issues, the DOE utilizes a licensing system to collect data on solid waste management and liquid waste management to improve on environmental planning in Belize. Apart from its regulatory functions of administering the Environmental Protection Act, its Amendments and Substantive Regulations, the DOE is responsible for the issuance of import and export permits and licenses. These licenses and permits include: License to Import Lead-Acid Batteries, Used Tires, ODS/halogenated gases, refrigeration/ air conditioning equipment and License to Export Scrap Metal and petroleum products.
