State Carbon Emissions Tool

This spreadsheet compares existing emissions in states, and allows you to compare that to other states and various targets.

This is not intended to recommend CO2 emissions outcomes or be a forecasting tool, but to consider emissions standards in relation to historic emissions trends, and depending on how EPA structures a carbon standard under Sec. 111(d), examine how a standard might compare across states and over time.

It's organized as a series of spreadsheet tabs. Below is a quick summary of what you can do with each tab:

Summary Graphics

• Choose a set of states
• Compare CO2 emissions; emissions rates in terms of fossil-intensity and total-intensity; and sources of generation
• Note: this tool is based on EIA fuel use, so it is an estimate of all electric sector emissions

Fossil Intensity Standard

• Choose a set of states to compare
• Choose a set of baseline years
• Input an intensity standard based on a coal and other fossil target (NRDC proposal)
• Input an intensity standard based on a percent reduction

Total Intensity Standard

• Choose a set of states to compare
• Choose a set of baseline years
• Input a total intensity standard (emissions / total generation, including non-emitting) based on a linear path from the baseline to a common end point in 2050
• Input a total intensity standard based on a percent reduction

Mass Based Standard

• Choose a set of states to compare
• Choose a set of baseline years
• Input mass based standard based on a percent reduction

Historic Emissions and MWh

• Allows you to examine the state data the other tabs are built on
• Select a state at the top

Notes

• Describes the data sources and assumptions
