Emissions-weighted carbon price in emissions trading systems
What you should know about this indicator
- This data primarily focuses on economic instruments targeting carbon dioxide (CO₂) emissions.
- In some cases these instruments also cover other greenhouse gases. However, any pricing mechanisms that specifically target non-CO₂ gases (such as methane or nitrous oxide) are not included.
- A country is considered to have a carbon tax or emissions trading system if at least one IPCC sector or gas is covered by the instrument. These instruments do not need to cover all sectors within the economy for this to apply.
- Only countries with a carbon tax at the national level are included.
- For each country, researchers calculate an emissions-weighted carbon price for the economy. To do this, they rely on two metrics:
- Carbon prices applied at the sectoral level (e.g. electricity, or road transport).
- Each sector's contribution to a country's CO₂ emissions (e.g. what percentage of a country's emissions come from electricity, or road transport). They then weight each sector's carbon price by the relevant sector's contribution to CO₂ emissions, and aggregate these figures to get an economy-wide weighted carbon price.
- A full technical note on the methodology is provided by the authors in this report.

How we process data at Our World in Data
All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
