Database structure and data categorisation

Database structure

The database includes a comprehensive record for each policy, covering a set of fields, as shown in the example in Table 1. With the help of an online form in a similar format, users can easily add policies and edit the information. The sector and policy type categories for each policy are those that appear in the country profiles of this study, to which additional subsectors were added as follows:

  • Electricity and heat: Nuclear, Coal, Oil, Gas, Renewables, CCS
  • Industry: Industrial energy-related, Fluorinated gases, Industrial N2O, Industrial process CO2, Waste (CH4), Oil and gas production (CH4)
  • Buildings: Heating and cooling, Hot water and cooking, Appliances
  • Transport: Light duty vehicles, Heavy duty vehicles, Electro-mobility, Air, Rail, Shipping
  • Agriculture and forestry: Agricultural CO2, Agricultural N2O, Agricultural CH4, Forestry

The policy instruments typology was developed based on the IEA policies and measures database, to which a set of new categories were added. The complete list of policy instrument options is provided in the table below:
