ADICO coding of Energy and Environment Regulations in Iran (1994-2018)
For examining environmental institutions, we checked the collection of environmental laws and regulations. The collection has two parts: national laws and international conventions and treaties. In this paper, we focused on national laws. and limited the scope to the regulations related to the industry sector and ignored those related to a specific province. In the energy sector, we reviewed the energy consumption pattern reform law. We also studied the executive procedure of clause 26 of this law, which defines penalties for disobedient industries. To industrial development, we investigated the rules and regulations for the establishment of production, industrial, and mining units.
Crawford & Ostrom (1995) introduced a grammatical syntax to analyze institutional statements called ADICO. ADICO refers to five components of institutional statements which are attribute (A), deontic (D), aim (I), condition (C), and or else (O). Different combinations of ADICO syntax shape three types of institutional statements: Rules include all components (ADICO); norms consist of the attribute, deontic, aim, and condition (ADIC); and shared strategies only have the attribute, aim, and condition (AIC). 
For ADICO coding, all clauses, paragraphs, and notes were copied to an excel sheet indicating the title of legislation, its issue or approval date, clause number, and note number. The list was generated in Farsi, and ADICO components were extracted from Farsi statements. In case a statement had several parts, we decomposed it to a few statements [31]. Then we checked if the institutional statement is relevant to IS or not. Our criteria was relevance to the industry section, industrial clusters, waste management, and energy consumption and recovery in the industry. In total, 183 IS-related statement were recognized. Then attribute, deontic, aim, condition, and sanction of those statements were identified as summarized below:

Attribute:
