AEC’s Emissions Measurement Inventory Tool (AEC-EMIT)

Author: Joshua R. Castigliego

December 2023

To support AEC’s emissions accounting work, Researcher Joshua R. Castigliego developed a spreadsheet-based tool—AEC's Emissions Measurement Inventory Tool (AEC-EMIT)—that provides users with an interface to build a greenhouse gas emissions inventory (and 20-year emissions projections) for a specific geographic region. Users can customize the tool by selecting greenhouse gases, sectors, subsectors, scenarios, sensitivities, and other information specific to their inventory. Users are also provided a dashboard to toggle select assumptions and parameters (e.g., global warming potentials, scenarios, and sensitivities, etc.). Summary tabs aggregate results across sectors and can be used to provide disaggregated sub-sector-specific results.

AEC-EMIT was utilized for AEC’s analysis on Puerto Rico’s 2019 and 2021 Greenhouse Gas Inventories Report.

AEC's Heating Electrification Assessment Tool (AEC-HEAT)

Client: Green Energy Consumers Alliance (GECA)

Author: Joshua R. Castigliego, Elisabeth Seliga

December 2023

On behalf of the Green Energy Consumers Alliance (GECA), Researcher Joshua R. Castigliego and Assistant Researcher Elisabeth Seliga developed a spreadsheet-based tool—AEC's Heating Electrification Assessment Tool (AEC-HEAT)—that (1) compares heating costs for various resource types and (2) evaluates the impact of new space heating electrification on regional peak electric use during the winter heating season.

AEC-HEAT houses two Dashboard tabs (i.e., Heating Costs Dashboard and Load Profile Dashboard) to provide users with an interface to evaluate impacts associated with space heating electrification. Users can customize the tool by selecting parameters from drop-down menus or inputting their own data values. AEC-HEAT is currently equipped to perform assessments specific to Massachusetts but has the ability to evaluate other jurisdictions pending data availability. AEC-HEAT's User Guide and Methodology document provides an overview of the tool as well as the methodological approach, parameters, and data requirements.

AEC-HEAT was utilized in the analysis for AEC’s December 2023 white paper, Space Heating with Heat Pumps: The Need for Alternative Rate Designs in Massachusetts.
