Note: Inventories were available for the following base years: 1990–2000, 2003 , 2004–05 (London);
2005 , 2006, 2007 (New York City); 2005 (Milan); 2000, 2004 (Mexico City); 2005 (Bangkok). The
inventory considered in the checklist is highlighted in italics. For Greater London, the checklist was fi lled
with reference to the 2003 inventory (called the London Energy and CO 2 Emissions Inventory), which
focuses on CO 2 emissions. The 2004–05 inventory (called the London Energy and GHG Inventory) also
comprises estimates of CH 4 , N 2 O, HFC, PFC, and SF 6. Estimates for Greater London Authority’s opera-
tions and buildings are included in the Climate Change Action Plan.
HFC = hydrofl uorocarbon; PFC = perfl uorocarbon; Q = quantifi ed but not included in the emission
values of the plan base year; Q* = non-CO 2 gases had been quantifi ed in a previous inventory (AMA
2007), but these emissions have not been included in the Climate Plan of Milan because they added a
negligible quantity to total emissions; n.a. = not applicable; n.s. = not specifi ed.

All inventories report at least emissions of carbon dioxide. Recent guidelines
recognize that collecting detailed local data on all Kyoto GHGs may be quite
onerous and thus suggest focusing on carbon dioxide and methane, the two most
relevant gases at the city level.
In terms of sectors, heating sector emissions are considered in all cities’
inventories, except Bangkok and Mexico City, because of their relatively warm
