3.国家温室气体人为排放清单（国家信息通报的执行情况）按五个主要部门编排，即：能源、工业加工、农业、土地利用的变化和林业以及废弃物。这项研究的目的是审查和计算巴西农业和土地利用的变化和林业温室气体缓解战略的潜力。第一步是分析巴西有关气候变化和减缓政策的官方和非官方文件。第二，详细阐述了2010-2020年时间框架的“一切照旧”情景和缓解情景，并计算了相应的相关温室气体排放量和清除量。此外，还采用了两种互补的办法来指出和量化主要的缓解办法：（a）遵循气专委1996年指南;（B）基于EX-ACT。巴西当局宣布，该国将把温室气体排放量从2020年的预计水平减少36.1%至38.9%。这是其他发展中国家也应该采取的积极立场。为了实现这一政府目标，农业和畜牧业部门必须减少1.33亿至1.66亿吨二氧化碳当量的排放量。这似乎是可以达到的，当面对我们的缓解选项值，这是在178.3至445吨二氧化碳当量之间的范围。政府对农业的投资是必要的，以尽量减少各部门为实现其目标所作的努力。
National inventories of anthropogenic greenhouse gas (GHG) emissions (implementation of the National Communications) are organized according to five main sectors, namely: Energy, Industrial Processes, Agriculture, Land-Use Change and Forestry (LUCF) and Waste. The objective of this study was to review and calculate the potential of greenhouse gas mitigation strategies in Brazil for the Agricultural and LUCF. The first step consisted in an analysis of Brazilian official and unofficial documents related to climate change and mitigation policies. Secondly, business as usual (BAU) and mitigation scenarios were elaborated for the 2010-2020 timeframe, and calculations of the corresponding associated GHG emissions and removals were performed. Additionally, two complementary approaches were used to point out and quantify the main mitigation options: a) following the IPCC 1996 guidelines and b) based on EX-ACT. Brazilian authorities announced that the country will target a reduction in its GHG between 36.1 and 38.9% from projected 2020 levels. This is a positive stand that should also be adopted by other developing countries. To reach this government goal, agriculture and livestock sectors must contribute with an emission reduction of 133 to 166 Mt CO2-eq. This seems to be reachable when confronted to our mitigation option values, which are in between the range of 178.3 to 445 Mt CO2-eq. Government investments on agriculture are necessary to minimize the efforts from the sectors to reach their targets.
