Currently, the Industry - Main page calculates final energy-related and process emissions by removing the amount of industry CCS from the pre-CCS totals. To determine the amount of CO2 to remove from each, it calculates a "Fraction of Industrial CCS Applied to Process Emissions." This variable simply calculates the fraction of total emissions from each industry that are from industrial processes.
Because we often want to target process CO2 emissions that have concentrated streams of CO2 (as opposed to energy-related emissions), the approach above will in most cases underallocate CO2 capture to process emissions and overallocate CO2 capture to energy-related emissions. Instead, we should explicitly track CCS for process emissions vs. energy-related emissions and then remove the respective totals on the Industry - Main page.
