Legal Framework of Co-operation
The framework for the co-operation between the entities of National GHG
Inventory System, i.e. MEECC, NTUA Inventory Team and the data
providers is based on: Circular 918/21-4-08 released by MEECC entitled “Structure and operationof the National Greenhouse Gases Inventory System- Roles andResponsibilities”, which includes a description of each entity’s
responsibilities, concerning the inventory preparation, data providing or otherrelative information.
 The appointment of specific focal persons of the involved competent
Ministries and Agencies
This formal framework has improved the collaboration between the entities
involved, assuring the timely collection and quality of the activity datarequired and solving data access restriction problems raised due toconfidentiality issues
