This dataset contains information on carbon pricing mechanisms (carbon taxes or cap-and-trade) introduced around the world since 1990. To date, it is the most comprehensive attempt at providing a consistent-across-jurisdiction description of carbon pricing mechanisms in terms of their sectoral (and fuel) coverage as well as the associated price signal.

It covers national and sub-national economic mechanisms relating to carbon emissions, and was developed from several key sources: Most notably, policy documents from countries and regions themselves. Secondly, from other sources such as the International Carbon Action Partnership.
