This dataset measures the impact of evolving carbon costs on firms’ financial indicators under different transition scenarios. The impacts are aggregated across countries and industries. Carbon Cost to Revenues/Assets indicators give an indication of how high these taxes will be in alternative policy scenarios in comparison to revenues/assets of the disclosing firms, along the transition through 2050. Revenues/Assets at risk indicator shows the share of firms that are expected to be severely impacted by carbon costs under the selected transition scenarios. Each indicator is calculated under two different assumptions: i) constant assets/revenues; and ii) adjusted by growth factors.
