Emissions-weighted carbon price: sources and methods

This note describes the sources and methods used to calculate the emissions-weighted carbon price (ECP), the average price applied to CO₂ emissions across all sources of emissions within a territorial jurisdiction by all carbon pricing mechanisms in force. It provides a transparent summary of the stringency of carbon pricing mechanisms in force within a given jurisdiction and allows for a straightforward comparison of that stringency across jurisdictions. It also describes the methodology behind two closely connected calculations: (i) sector-level carbon prices (by IPCC categories of emissions by sources and by categories of economic activity, respectively), (ii) industry- and country-level carbon costs.
