Would all businesses need to purchase Carbon Shares in order to do business in California?
No. Only upstream businesses- the businesses which produce or import fossil fuels into the California economy would need to purchase Carbon Shares. Retailers such as gas stations would not need to purchase Carbon Shares. Consumers would not need to purchase Carbon Shares. By regulating at the point where fossil fuels enter the economy, there is no need to regulate further downstream in the economy, and there are fewer businesses to regulate.
