Food systems Emissions shares, 1990-2019
收藏资源简介：
<strong>Greenhouse gas emissions from agri-food systems </strong> <strong>(1990-2019)</strong> <strong>Overview</strong> We present results from the FAOSTAT emissions shares database which disseminates emissions from all economic sectors and from agri-food systems by gases (CO<sub>2</sub>, CH4, N<sub>2</sub>O, F-gases and their total in CO<sub>2</sub>eq) relative to 236 countries and territories over the period 1990 – 2019. In 2019, global greenhouse gas emissions from all economic sectors totaled about 54 billion tonnes CO<sub>2</sub>eq (54 Gt CO<sub>2</sub>eq), emissions from agri-food systems totaled 16.5 billion tonnes (Gt CO<sub>2</sub>eq) representing 31 percent of the total anthropogenic emissions from all economic sectors. This dataset focuses on emissions from agri-food systems which includes data on emissions from the farm-gate, land use change and pre- and post-production. The sum of these three sectors comprises the agri-food system emissions (16.5 Gt CO<sub>2</sub>eq). Pre- and post-production include emissions from: fertilizers manufacturing, on-farm electricity use, food processing, food transport, food retail, food waste disposal, food household consumption and food packaging. <strong>Data Structure</strong> The data is structured as a tabular data with attributes: AreaName, ISO3, ItemName, ElementName, Year, Value, Unit. <strong>Attributes (Columns)</strong> Attributes in the data are defined as below: <strong>Name</strong> <strong>Descriptions</strong> <strong>AreaName</strong> characterizes all countries including world and regional aggregates <strong>ISO3</strong> represents three letter ISO3 country codes (not all regional aggregates have ISO3 country codes) <strong>ItemName</strong> represents all items covered in the data <strong>ElementName</strong> represents all gases covered in the data <strong>Year</strong> period covered by the data <strong>Value</strong> represents the emissions value <strong>Unit</strong> Unit of measurement (in this data emissions are measured in kilotonnes) <strong>Files included in the dataset</strong> We have included two files available for downloaded. The csv file contains the data in .csv format and a excel file contains data in .xlsx format. <strong>Global warming potential (GWP)</strong> In this data, the emissions total (CO<sub>2</sub>eq) is computed by applying the GWP values from the IPCC Fifth Assessment Report (AR5) as given below: <strong>Greenhouse gas</strong> <strong>GWPAR5 (IPCC, 2014)</strong> <em>Single</em> <em>gases</em> N<sub>2</sub>O 265 CO<sub>2</sub> 1 CH<sub>4</sub> 28 <em>F-gases </em> HFC-23 12,400 HFC-32 677 HFC-41 116 HFC-125 3,170 HFC-134 1,120 HFC-134a 1,300 HFC-143 328 HFC-143a 4,800 HFC-152 16 HFC-152a 138 HFC-161 4 HFC-227ea 3,350 HFC-236cb 1,210 HFC-236ea 1,330 HFC-236fa 8,060 HFC-245ca 716 HFC-245fa 858 HFC-365mfc 804 HFC-43-10mee 1,650 Sulfur hexafluoride (SF<sub>6</sub>) 23500 Nitrogen trifluoride (NF<sub>3)</sub> 16,100 PFC-14 6,630 PFC-116 11,100 PFC-218 8,900 PFC-318 9,540 PFC-31-10 9,200 PFC-41-12 8,550 PFC-51-14 7,910 PCF-91-18 7,190 µGWP 5,195 <strong>Data Sources</strong> FAOSTAT climate change, emissions shares data, analytical brief.
