Non sono riuscito a reperire i dati di emissione dei 6 gas a livello mondiale. L’inventario delle emissioni non \u00e8 una cosa semplice soprattutto uscendo dai paesi pi\u00f9 industrializzati. I dati disponibili sono a livello nazionale ed europeo.<\/p>\n

A livello globale, il peso dell\u2019Italia rispetto alle emissioni globali di gas-serra si aggira intorno al 2%. Secondo i dati dell\u2019Agenzia Internazionale dell\u2019Energia, le emissioni di CO2 originate dai processi di combustione nel nostro Paese rappresentavano l\u20191,94% del totale delle emissioni mondiali nel 1990 e l\u20191,80% nel 2001. <\/p>\n

L\u2019obbligo di elaborare gli inventari delle emissioni di gas-serra, gi\u00e0 previsto dalla Convenzione-quadro, ha assunto un ruolo di gran lunga pi\u00f9 importante con l\u2019entrata in vigore del Protocollo di Kyoto, dal momento che gli inventari costituiscono lo strumento utilizzato per valutare se le Parti stanno osservando gli impegni di riduzione. <\/p>\n

Nell’anno 1998 (dati ANPA 2000) le emissioni in Italia erano pari a:<\/p>\n

– le emissioni di tutti i gas-serra con-siderati dal Protocollo di Kyoto nel 1998 risultano superiori del 4,7% a quelle del 1990 (a fronte di un impegno nazionale di riduzione delle emis-sioni nell\u2019ambito del Protocollo pari al 6,5% nel periodo 2008-2012 rispetto ai livelli del 1990); <\/p>\n

– in particolare le emissioni di CO2 nelle emissioni totali nel 1998 risultano superiori del 6,6% a quelle del 1990 (esiste un impegno europeo di stabilizzazione delle emissioni di CO2 dell\u2019intera Unione Europea nel 2000 rispetto ai livelli del 1990). <\/p>\n
