Struttura produttiva territoriale ed efficienza di emissioni attraverso la NAMEA regionale

[Autom. eng. transl.] The relationships between regional production structure and greenhouse gas emissions using the related NAMEA (National Accounting Matrix including Environmental Accounts) data for Lazio to the year 2000. The goal is to show how NAMEA data can provide a good basis for understanding relations between the economy and emissions, and can therefore provide support to public decision makers. Although ISTAT has produced NAMEA accounts at national level for 1990-2002, the one for Lazio for 2000 is the first regional-scale NAMEA produced in Italy. In the work, an analysis was applied to NAMEA Lazio shift share in order to examine what are the determining factors of the emissions efficiency gap atmospheric conditions between Lazio and the average Italian situation. The shift share analysis allows to isolate distinct forces: the the first linked to the structural or industrial mix of the territory, the second based on the specific emission efficiency of the individual sectors, the third consisting of the covariance of the first two factors. In this version, between the ten emission categories available in NAMEA, only those of CO2, N2O and CH4 are examined.
