GHG Modeling

Appendix A: Initiative 1631 Funding to Offset Increases In Lower Income Energy Burdens

To project the potential for revenue to be used for relieving the energy burden of people with lower incomes CaPI examined data on median household income by county (American Community Survey (ACS), 2016) and the share by county of income to poverty levels (also from the ACS, 2016). By this method, 39.7% of the populations would be covered by either the federal poverty line or the area median income designation. Including 40.8% in rural counties and 39.4% in urban counties.

Appendix: Wasted Energy additional details

Section 1: Updating the Sankey diagram
Sankey Diagrams, like those produced by LLNL, are an information-rich visual depiction of energy or other (e.g. carbon, money) flows from inputs to final use.

Section 2: Carbon content of wasted energy
CaPI analysis estimates around 50 million metric tons of carbon dioxide (MtCO2) associated with wasted energy in 2015.

Revenue & Emissions Preliminary Impact Analysis – Senate Bill 6203

Using a proprietary modeling system, the Washington Business Alliance analyzed the expected outcomes of Senator Palumbo’s Carbon Tax Bill, Senate Bill 5930. SB 5930 is projected to generate a peak of roughly $1.8 billion/year in 2024 (in USD, 2018), and reduce greenhouse gas emissions by a similar amount as the Clean Air Rule (CAR): around 180 million metric tons of carbon dioxide equivalents (MtCO2e) give or take around twenty percent. Emissions in 2035 are projected to be around 9% lower than 1990 levels.
