CleanEnergy Emissions Calculator

Greenhouse gas reporting can become a spreadsheet-heavy process before a manufacturer has enough internal systems to support it. The product needed to turn workbook setup, facility details, activity data, calculations, and reporting into a guided flow that a team could understand without becoming emissions-accounting specialists.

The work was organized around a few practical decisions that kept the product direction clear.

• Structured the product around the Greenhouse Gas Protocol workflow: company workbook, facilities, inventory years, Scope 1 activity, Scope 2 activity, calculations, and final report.
• Modeled facility and inventory-year setup first so later emissions entries can be grouped by manufacturing location, year, and operational context.
• Supported emissions categories for stationary combustion, mobile combustion, and purchased electricity, with calculated gas totals and CO2e rollups.
• Kept the portfolio version self-contained with seeded demo data so visitors can explore workbook setup and report output without credentials or a live backend.

Built a demo-ready emissions calculator with workbook metadata, facility and inventory-year management, Scope 1/2 calculation structure, annual emissions summaries, facility breakdowns, emissions intensity context, and PNG/PDF report export actions.

The core product problem was translating the Greenhouse Gas Protocol into a workflow that feels like a manufacturing workbook instead of a compliance spreadsheet. Each setup step gives later calculations enough context to group and explain the output.

• Company metadata and NAICS code establish the workbook.
• Facilities capture location, eGRID subregion, square footage, and notes.
• Inventory years create a baseline for year-over-year comparisons.
• Scope 1 and Scope 2 activity categories organize emissions inputs around how the work is actually reported.

The calculator keeps the public-facing workflow simple while preserving the emissions-accounting structure behind it. Activity rows can produce gas-level results, which then roll up by facility, year, and scope.

• Stationary combustion covers fuel usage for heat, steam, power, and process loads.
• Mobile combustion supports fleet activity by fuel or distance.
• Purchased electricity supports Scope 2 utility activity.
• Results include CO2, CH4, N2O, CO2e, biogenic CO2, and emissions intensity context.

The report view turns the calculator into something a manufacturing team can communicate. Instead of ending at raw rows, the product presents annual totals, gas charts, facility breakdowns, and export actions.

• Annual overview charts compare reporting years.
• Facility-level sections show where emissions are concentrated.
• PNG and PDF export actions make the report easier to share outside the app.

The portfolio build runs with a local demo workspace and seeded manufacturer data. Visitors can review workbook structure and report output without credentials, live storage, or private customer records.
