The connection between 2006 IPCC GHG inventory methodology and ISO 14064-1 certification standard – A reference point for the environmental policies at sub-national scale

摘要

The article shows how a joint application of the 2006 IPCC methodology and the ISO 14064-1 standard of certification, as well as the co-operation between academic, legislative and administrative organizations, are important points for a sustainable management of an administrative jurisdiction, providing positive environmental effects. The administrative systems can choose validated ISO 14064-1 GHG inventories, produced in time series, as a strategy tool for local management, as a compass to orient future policy decisions. The Province of Siena (Tuscany, Central Italy) was one regional system in Europe to achieve the ISO 14064-1 certification of its GHG inventories, developed in time series applying the 2006 IPCC methodology. The results of the time series (year 2006–2010) of GHG inventories elaborated for the Province of Siena point out that the performed environmental management policies may bring about a significant reduction of GHG emission released to the atmosphere over time (net emission: 449 Gg CO_(2eq) in 2006, 84 Gg CO_(2eq) in 2010). The experience of the Province of Siena can be considered a significant reference model for all public authorities at the micro and macro scale who are interested in reducing GHG emission.
