Emissions from pre and post agricultural production

The FAOSTAT domain “Pre- and Post-Production” (PPP) includes the greenhouse gas (GHG) emissions, and related activity data, generated from pre- and post-agriculture production stages of the agri-food systems.  Data are computed following the Tier 1 methods of the Intergovernmental Panel on Climate Change (IPCC) Guidelines for National greenhouse gas (GHG) Inventories (IPCC, 1996; 1997; 2000; 2002; 2006; 2014). The domain includes methane (CH4), nitrous oxide (N2O), carbon dioxide (CO2) and CO2 equivalent (CO2eq) emissions from the above activities as well as the aggregate fluorinated gases (F-gases) emissions. Estimates are available by country, with global coverage for the period 1990–2020. The database is updated annually.The FAOSTAT domain disseminates information estimates of CH4, N2O, CO2 emissions, F-gases, their aggregates in CO2eq in units of kilotonnes (kt, or 106 kg), and the underlying activity data. CO2eq emissions are computed by using the IPCC Fifth Assessment report global warming potentials, AR5 (IPCC, 2014). Data are available for most countries and territories, for standard FAOSTAT regional aggregations, and for Annex I and non-Annex I country groups.

FAOSTAT 数据域“生产前和生产后”（PPP）涵盖了来自农业食品系统中农业生产前和后阶段的温室气体（GHG）排放以及相关活动数据。这些数据计算遵循《政府间气候变化专门委员会（IPCC）国家温室气体（GHG）清单指南》的 Tier 1 方法（IPCC，1996；1997；2000；2002；2006；2014）。该域包括甲烷（CH4）、氧化亚氮（N2O）、二氧化碳（CO2）及二氧化碳当量（CO2eq）的排放，以及综合氟化气体（F-gases）的排放。估计数据按国家提供，覆盖全球范围，时间跨度为1990年至2020年。数据库每年更新一次。FAOSTAT 数据域发布甲烷、氧化亚氮、二氧化碳、F-气体及其在二氧化碳当量中的合计排放估计值，单位为千吨（kt，或10^6 kg），以及相关的活动数据。二氧化碳当量排放的计算采用 IPCC 第五次评估报告的全球变暖潜力，AR5（IPCC，2014）。大多数国家和地区的标准 FAOSTAT 区域汇总以及附件I和非附件I国家组的排放数据均可用。
