Food systems Emissions shares, 1990-2019

Greenhouse gas emissions from agri-food systems

(1990-2019)

Overview

We present results from the FAOSTAT emissions shares database which disseminates emissions from all economic sectors and from agri-food systems by gases (CO2, CH4, N2O, F-gases and their total in CO2eq) 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 CO2eq (54 Gt CO2eq), emissions from agri-food systems totaled 16.5 billion tonnes (Gt CO2eq) 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 CO2eq).

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.

Data Structure

The data is structured as a tabular data with attributes: AreaName, ISO3, ItemName, ElementName, Year, Value, Unit.

Attributes (Columns)

Attributes in the data are defined as below:

Name

Descriptions

AreaName

characterizes all countries including world and regional aggregates

ISO3

represents three letter ISO3 country codes (not all regional aggregates have ISO3 country codes)

ItemName

represents all items covered in the data

ElementName

represents all gases covered in the data

Year

period covered by the data

Value

represents the emissions value

Unit

Unit of measurement (in this data emissions are measured in kilotonnes)

Files included in the dataset

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.

Global warming potential (GWP)

In this data, the emissions total (CO2eq) is computed by applying the GWP values from the IPCC Fifth Assessment Report (AR5) as given below:
