A factual description of the current Kreeshiv Energy Emission Monitoring Tool release, prepared for technical review, copyright-registration support, implementation discussions, and audit-support reference.
Current documented application version
Public pages, protected workspace, and PDF reporting
Reflects the currently deployed architecture
The current release is a single Next.js application deployed on Vercel. Public information, authentication, the protected calculator, the calculation engine, and PDF reporting are maintained in one source project.
Public visitors view product information. The configured administrator signs in to use the GHG workspace.
App Router pages, server route handlers, protected server rendering, client workspace, metadata, and static assets.
Scope totals, category analysis, warnings, on-screen report, and a downloadable client-ready PDF.
Product, resource, contact, privacy, terms, disclaimer, cookie, deletion, and security pages.
Environment-based credentials, HMAC signing, session verification, protected route enforcement, and logout.
Organisation setup, activity input, browser persistence, live metrics, summaries, and report controls.
Workbook-derived factors, country grid factors, formulas, validation rules, scope mapping, and PDF data.
Server-rendered public pages present the product, solutions, resources, legal notices, security information, and contact channels. Route metadata, canonical URLs, structured data, robots rules, and the XML sitemap support discoverability.
The login endpoint checks a configured administrative username and password on the server. A successful login creates a signed HTTP-only session cookie before the protected workspace is served.
Users configure organisation identity, location, reporting period, employee count, and activity quantities covering fuel, energy, transport, refrigerants, water, waste, materials, travel, food, freight, commuting, and home working.
Typed factor tables are derived from the supplied GHG calculation workbook. Each factor retains its unit, source sheet, and source cell or range where available, supporting traceability from input to output.
Deterministic TypeScript functions convert activity data to kg CO2e, group results into Scope 1, Scope 2, and selected Scope 3 categories, convert totals to tonnes, and flag missing country or category factors.
The workspace provides total and scope metrics, category contribution views, source summaries, validation warnings, tabular outputs, an on-screen report, and a client-ready downloadable PDF.
Factors are mapped from the supplied workbook GHG_emissions_calculator_base.xlsx. Calculation categories retain workbook sheet and cell references where available. Country-specific electricity factors are selected from the organisation or activity country.
The administrator signs in through the server-validated login flow.
Organisation, location, employee count, and reporting period are confirmed.
Quantities are recorded against the relevant fuel, energy, travel, waste, water, freight, and other categories.
The calculation engine applies the configured factors and recomputes scope and category totals immediately.
Missing grid or country factors appear as on-screen warnings that must be resolved or documented.
The dashboard is reviewed and a dated PDF is generated for management or audit-support use.
Recalculation, scope aggregation, category ranking, validation, browser-state saving, report rendering, and PDF preparation occur automatically after user input.
Warnings are displayed inside the workspace. The current release does not send email, SMS, messaging, ticketing, or automated escalation notifications. Review, correction, approval, and follow-up remain human-controlled.
The current release has no central application database. Calculator information stays in the user's browser on that device; authentication is handled separately through the server and a signed cookie.
Values entered by the authenticated user in the protected workspace.
The current state is persisted under a dedicated browser-local key on the same device.
Deterministic calculations produce category, scope, total, and warning outputs.
Results are displayed for review and can be downloaded as a system-generated PDF.
| Data set | Location | Current behavior |
|---|---|---|
| Credentials and signing secret | Vercel server environment | Used only by server-side authentication; credentials are not written to browser storage. |
| Session | Signed HTTP-only cookie | Expires after 8 hours, or 30 days when “Remember me” is selected. |
| Calculator state | Browser local storage | Persists on the current browser/device until the user or browser clears it. |
| Reports | Generated in the browser | Downloaded by the user; the application does not centrally archive generated files. |
POST /api/login accepts the login form, validates credentials server-side, and establishes the session.The tool can support consultancy, evidence preparation, management review, and carbon-footprint discussions connected with customer or audit programmes such as SA8000, WRAP, RJC, and Disney FAMA. It organises GHG activity data and produces supporting reports; it does not itself perform certification or social-compliance audits.
No accreditation or affiliation is implied. Certification-body relationships, programme approvals, audit conclusions, and use of third-party marks must be confirmed and documented separately by the legally authorised organisations.
Typed Next.js and React source for the public site, protected workspace, calculations, authentication, and reports.
The supplied GHG emissions calculator workbook used as the traceable base for factor and worksheet mappings.
Scope categories retain worksheet or range references, supporting review against the original workbook logic.
Public pages, authenticated dashboard views, validation messages, report preview, and downloadable PDF output.
