Greenhouse Gas Modeling

Modeling Tools

Under the guidance of Kevin Tempest, our Research and Data Scientist, Clean & Prosperous Institute equips policymakers, businesses, and organizations with valuable insights into the cost-effectiveness and public advantages of policies and technologies aimed at reducing carbon emissions. In addition to our published reports like “Washington’s Decisive Decade” and “Building Back Better,” the Institute has developed proprietary modeling tools to enhance decision-making processes.

Fiscal Scenario Modeling

In preparation for the 2023 Legislative session, we designed a tool to project cap-and-invest allowance revenue and construct a budget of expenditures aligning with the mandated spending overlay requirements.

GHG Explorer (No Longer Updated)

Our GHG Explorer serves as a tool to assess carbon pricing policy proposals for lowering greenhouse gas emissions. Reviewed for accuracy by the Washington Departments of Commerce and Ecology, this model was featured in numerous legislative hearings and utilized to shape policy development. Built upon the state’s Carbon Tax Assessment Model (CTAM), the Explorer incorporates customizable layers that swiftly and comprehensively evaluate policy design considerations, offering interconnected outputs that are responsive and accurate. For a practical example, refer to our analysis of SB 6203 from the 2018 Legislative Session.

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.

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.

House Bill 1646: Revenue and Emissions Impact – Preliminary Analysis

House Bill 1646: Revenue and Emissions Impact – Preliminary Analysis

The Washington Business Alliance developed the Washington State GHG Reduction Explorer to project the outcomes of various policy proposals that tax/regulate greenhouse gas emissions. We evaluate two scenarios for this analysis: one with what we believe are relatively optimistic assumptions about Clean Energy Account investments and one with what we believe are relatively pessimistic assumptions about the Clean Energy Account investment cost-effectiveness.
