Green Practices Guideline for Fisheries Sector

Water consumption: An energy usage by the organisation and its sub-entities for its operations and activities. Alternative water: Refers to water from alternative sources such as rainwater or reclamation processes. Baseline year: A reference point in time against which a measure of consumption and/or production in the present and/or future are measured. Reporting period: The time span for which the instrument assesses the organisation. Unless required otherwise time span should be one year. 2.2. UNIT OF MEASUREMENT Percentage (%) of alternative water used with reference to the total water used within the organisation. 3. METHODOLOGY 3.1. DATA SOURCE Water consumption: Metered water usage readings (i.e., m 3 ), utility bills (i.e., m 3 ), or any other documents recording the water consumption for the organisation. Alternative water consumption: Metered alternative water consumption readings (i.e., m 3 ), utility bills (i.e., m 3 ), or any other documents recording the alternative water consumption for the organisation. In the event that consumption data for alternative water is not available, alternative water production readings can be used. 3.2. DATA COLLECTION METHOD Water consumption: • Metered water usage reading showing a consumption of water over a period of time. Typically, meter reading is provided with a monthly time span. The total water consumed shall be computed by taking the total meter readings for individual months over the period of the reporting year. In the event that more than one water source is available, the sum of the metered readings shall be considered. • Bills of quantities of water purchased shall be used to represent consumption of water over a period of time. The total water consumed shall be computed by taking the total quantities for the period of the reporting year. In the event that more than one water source is consumed, the sum of the quantities of water consumed shall be considered. • Other forms of evidence acceptable include purchase invoices, bills of lading, and other similar documents. • Other documents that can be used as evidence are purchase invoices received by utility providers or suppliers for water purchased with the assumption that the water purchased is consumed within the reporting period. Alternative water consumption: • Metered alternative water usage reading showing a consumption of alternative water over a period of time. Typically, meter reading is provided with a monthly time span. The total alternative water consumed shall be computed by taking the total meter readings for individual months over the period of the reporting year. In the event that more than one alternative water source is available, the sum of the meter readings shall be considered. • Bills of quantities of alternative water purchased shall be used to represent consumption of alternative water over a period of time. The total alternative water consumed shall be computed by taking the total quantities for the period of the reporting year. In the event that more than one alternative water source is consumed, the sum of the quantities of alternative water consumed shall be considered. • Other forms of evidence acceptable include purchase invoices, bills of lading, and other similar documents. • Other documents that can be used as evidence are purchase invoices received by utility providers or suppliers for alternative water purchased with the assumption that the water purchased is consumed within the reporting period. 86 GREEN PRACTICES GUIDELINE FOR FISHERIES SECTOR (AQUACULTURE)
