Baseline

The GHG inventory tab is step 1 of the pipeline: you can only reduce what you have measured. It covers Scope 1 (stationary and mobile combustion, fugitive, process), Scope 2 (purchased electricity, heat, steam, cooling) and all fifteen Scope 3 categories, quantified per ISO 14064-1:2018 and the GHG Protocol Corporate Standard, with IPCC AR6 100-year GWPs and biogenic CO₂ reported separately. Every emission factor is editable, so supplier-specific or national data can replace the defaults; grid electricity factors switch with the country you choose.

You don't have to type everything: drop a utility bill export, fuel log, travel report or meter sheet (CSV, tab-separated or plain text) into the import box, or paste rows. Each row is matched to an activity, converted to the right unit (MWh to kWh, gallons to litres, miles to km) and shown in a review table with a confidence flag; nothing enters the inventory until you approve it.

Scope 2 is dual-reported as the GHG Protocol requires: location-based from the grid average, and market-based from what you actually bought. A built-in helper walks the hierarchy (supplier factor, RECs/I-RECs, PPA factor, residual mix) and computes the market-based total from the electricity already in your inventory. The whole inventory exports to CSV for verification under ISO 14064-3.

The Permits tab reads a facility's consent three ways: upload the permit as a PDF, paste the conditions section as text, or type limits in yourself. PDF upload extracts the document's own text layer entirely in your browser (via pdf.js, from a public CDN), and the file is never sent anywhere; it then drops that text into the same paste box for you to check. It only works when the PDF has real, selectable text; a scanned or photographed PDF gets an explicit "no text found" message rather than a silent wrong answer.

Clicking "Scan for limits" is pattern-matching, not a live AI reading. This tool has no running connection to an AI model, so it looks for phrases like "shall not exceed", "between X and Y", and "Name: value unit" lines, and will miss unusual formatting. Nothing drives your results until you tick "confirmed" on a row. For a genuine AI-generated read, the "Bring your own Claude turn" panel copies a ready-made prompt for you to paste into Claude and imports its reply back into the same review table, still unconfirmed until you check each row.

Once a limit is confirmed, log dated readings against it, or use the monthly compliance tracker to enter each month's actual values per permit. Every entry is checked against its limit (within / approaching / exceeded) and against recent readings for a spike (over 25% above the trailing average), with alerts the moment a limit is exceeded and a colour-coded month-by-month history. The compliance plan is generated the same rule-based way: exceedances first, then parameters trending toward their limit, then anything unconfirmed or unmonitored.

Fill in the optional "Financial feasibility" fields on the project form (economic life, discount rate, extra O&M cost, non-credit annual savings, estimated tCO2e/yr avoided, and an assumed credit price), and Baseline runs the standard techno-economic formulas: simple payback (capex ÷ net annual cash flow), NPV (discounted cash flow over the stated life and rate), and IRR (solved numerically), twice, once excluding carbon credit revenue and once including it. This entire section is a separate calculator from the eligibility score. None of these numbers feed the score, so leaving tCO2e/yr or credit price blank never changes a project's eligibility band; it only means the "with credits" scenario can't be computed yet.

The two scenarios side by side are the point: they show, in concrete payback and NPV terms, how much a credit revenue stream can change whether a decarbonisation retrofit clears a hurdle rate. These are scenario calculations from whatever numbers you enter, not verified engineering or financial figures. The same "check the assumptions" caveat that applies to the eligibility score applies here too.

A workable in-class exercise: give students a real or representative process retrofit (e.g. a distillation column heat-integration project, a catalytic converter upgrade, or a CO2 capture unit on a reformer), have them estimate the emission reduction from a mass/energy balance, add it as a project here with their own financial assumptions, and compare the eligibility band and feasibility verdict across India and the US. The sample "Vadodara ammonia plant CO2 capture retrofit" project on the Portfolio tab is a pre-filled illustrative example that runs both, useful as a live walkthrough before students build their own.
