The Mexico greenhouse gases emissions inventory: Results and methodology contributions on agriculture and land use change

Conference ·
OSTI ID:471058
The 1990 Preliminary Greenhouse Gases Emissions Inventory was released in October 1995. It was carried out with sponsorship of the US CSSP and UNEP. It was the product of a partnership between government and academic institutions. Total emissions of CO{sub 2} are 433,721 Gg. Land use change emissions of CO{sub 2} are 111,784 Gg which accounts for 25.8% of the national total. Methane is the second largest greenhouse gas, 3,801 Gg. When its warming potential is accounted for, it is equivalent to 18% of total greenhouse gases emissions. Livestock is the source of 51.3% of these emissions. Methane emissions from cattle and CO{sub 2} emissions from land use change are strongly associated. Besides the results on emission estimates, the inventory work allowed them to use and to improve on IPCC methodologies. Serious miscalculations may result from straightforward application of Tier 1 or even and even of Tier 2 IPPC methodologies for methane emissions from cattle. The need for nation specific forest categories and for more detailed information on the dynamics of land use change was shown. An analysis of emission trends shows the possibility of associated mitigation options for methane and CO{sub 2} from these two sources. A comparative analysis for mitigation potential of methane emissions from large and small scale cattle raising is under way.
