The present study analyzes the impact of carbon pricing along with other policies on the value of fossil fuel resources, CO2 emissions, and economic welfare. It employs a model based on the Hotelling analysis of resource values and calibrates this approach to data on fossil resources, costs, demands, and CO2 emissions. Total fossil-fuel resource rents are estimated to be $17 trillion (2021 US$) without carbon pricing. Oil and gas rents are unchanged for low carbon taxes but would decline by 40% with a $100/tCO2 price. The losses in producer values would be only about 10% of the carbon tax revenues. The study also shows that other policies – such as ones involving ethical investing or subsidies for renewable energy – are very inefficient and poor substitutes for carbon pricing.
