title: Net-zero 1.5 °C sectorial pathways for G20 countries: energy and emissions data to inform science-based decarbonization targets

description: This data for global, regional (EU-27), and country-specific (G20 member
 countries) energy and emission pathways required to achieve a defined
 carbon budget of under 450 Gt/CO2, developed to limit the mean global
 temperature rise to 1.5°C, over 50% likelihood. The data were calculated
 with the 1.5°C sectorial pathways of the One Earth Climate Model—an
 integrated energy assessment model devised at the University of Technology
 Sydney (UTS).  The data consist of the following six zip-folder
 datasets (refer to Section 2 for an explanation of the data):
 1.       Appendix
 folder: Each file contains one worksheet, which summarizes the overall
 1.5°C scenario.
 2.       Sector
 folder (XLSX): Each file contains one worksheet, which summarizes the
 industry sectors analysed.
 3.       Sector
 folder (CSV): The data contained are the same as those described in point
 2. 4.       Sector
 emissions folder: Each file contains one worksheet, which summarizes the
 total annual emissions for each industry sector.
 5.       Scope
 emissions folder (XLSX): Each file contains one worksheet, which
 summarizes the total annual emissions for each industry sector—with the
 additional specificity of emission scope.
 6.       Scope
 emissions folder (CSV): The data contained are the same as those described
 in point 5.
description: The data consist of the
 following six zipped dataset folders, each containing 21 separate files
 for each of the areas assessed. 1.       Appendix zip folder: contains 21 XLSX files.
 Each file contains one worksheet, which summarizes the overall 1.5 °C
 scenario. This tab is called the ‘Appendix’ and contains: electricity
 generation (TWh/a), transport—final energy (PJ/a), heat supply and air
 conditioning (PJ/a), installed capacity (GW), final energy demand (PJ/a),
 energy-related CO2 emissions (million tons/a), and primary energy demand
 (PJ/a). 2.       Sector zip folder (XLSX): contains 21 XLSX
 files. Each file contains one worksheet, which summarizes the industry
 sectors analysed. Key industry metrics are provided, such as the energy
 and carbon intensities of the GICS sectors analysed. Due to industry
 specificity—and the choice of methodology—the units of data vary between
 the different sectors. 3.       Sector zip folder (CSV): contains 21 CSV files.
 The data contained are the same as those described in point 2. However,
 the data have been organized in a database layout and saved in the CSV
 file format, significantly improving data parsing.
 4.       Sector emission zip folder: contains 21 XLSX
 files. Each file contains one worksheet, which summarizes the total annual
 emissions (MtCO2/a) for each industry sector.
 5.       Scope emissions zip folder (XLSX): contains 21 XLSX
 files. Each file contains
 one worksheet, which summarizes the total annual emissions (MtCO2/a) for
 each industry sector—and specifies the emission scopes. This tab also
 provides an additional breakdown of emissions into the categories of CO2
 and total GHG emissions. Two accounting methodologies are presented: (i)
 the OECM approach, which defines Scope 1 emissions as those related to
 heat and energy use; and (ii) the production-centric approach, which
 places the emission burden of other non-energy and Scope 3 emissions on
 the producer, because they are categorized as Scope 1
 emissions. 6.       Scope emissions zip folder (CSV): contains 21
 CSV files. The data contained are the same as those described in point 5.
 However, the data have been organized in a database layout and saved in
 the CSV file format to improve data parsing.
 The six datasets are
 summarized in Table 1, with further information on the data presented in
 the following sub-sections. Table 1: Overview of the data

The dataset contains the following scenario output parameters: 4.       Carbon intensity: current and future carbon intensities per unit of product or service; for example, in tons of CO2 per ton of steel produced (tCO2/ton steel) or grams of carbon dioxide per passenger kilometer (gCO2/pkm). 5.       Scope 1, 2, and 3 emissions: datasets for each of the industry sectors and countries analysed. In addition to the emissions data, the deviations of the emissions from those of the year 2019 are provided. 6.       Country scenarios: complete country scenario datasets of historical data (2012, 2015–2020) and future projections (2025–2050 in 5-year increments). Energy demand and supply data by technology, fuel, and sector are provided, including the overall energy and carbon emissions balance of the country analysed. 1.2.    Geographic resolution: country data provided The dataset contains data for the following 21 countries and regions: ·    Regions: global, EU-27 ·    Countries: G20 member countries—Canada, USA, Mexico, Brazil, Argentina, Germany, France, Italy, United Kingdom, Türkiye, Russian Federation, Saudi Arabia, South Africa, Indonesia, India, China, Japan, South Korea, and Australia 1.3.    Sectorial resolution: industry sector data provided The dataset contains data for the following industry sectors: Agriculture & food processing, forestry & wood products, chemical industry, aluminum industry, construction and buildings, water utilities, textile & leather industry, steel industry, cement industry, transport sector (aviation: freight & passenger transport; shipping: freight & passenger transport; and road transport: freight & passenger transport). 1.4.    Time resolution The scenario data are provided for the years 2017, 2018, 2019, 2020, 2025, 2030, 2035, 2040, 2045, and 2050.
