Project overview
Carbon & Energy Calculator
Enter fuel or energy usage. A configured factor is applied automatically, and draft emissions records into the existing ESG indicators for review.
Carbon & energy overview
Selected period and site; totals use saved calculations only. They are unverified until reviewed.
Scope 1 + Scope 2 + Scope 3
Sum of saved calculations within each category; illustrative until reconciled and reviewed. Never add exported/avoided emissions to this chart.
Generation and avoided emissions
Metered exports (MWh) and estimated avoided emissions (tCO₂e) are shown separately. Units are not directly comparable.
Calculation register
| Site / period | Activity | Quantity | Factor, source | Calculated value | ESG record |
|---|
Deleting a calculation also removes the linked Draft ESG result, but cannot remove a submitted or verified result. Edit by removing the draft calculation and creating a corrected one. Local changes are autosaved; online multi-user saving requires Supabase setup.
Factor selection and calculation methodology
The calculator deliberately does not automatically select a Zimbabwe emissions factor. You must enter the factor in the displayed unit, its source and reference year. For diesel, the previous 2.68 kg CO₂/litre was an illustrative direct-combustion CO₂ value, not an approved CE tCO₂e factor. For Zimbabwe, the 2025 NDC cites historical and projected grid-average factors, but a project-specific displaced-generation factor for avoided-emissions claims needs further methodological review.
Useful references: UK government 2026 conversion factors (check applicability to Zimbabwe), Zimbabwe NDC 3.0, GHG Protocol guidance.
Indicators & targets
Grouped by ESG topic. Related measures are shown together, with distinct definitions and units retained.
Environmental Compliance & Technical Monitoring
Conditional indicators are excluded from normal ESG reporting and entry while inactive. Activate only when an approved project document or risk assessment requires monitoring.
Record a result
Select a site first, then search for an indicator by code or name. Draft fields auto-save while you type.

Risk & action register
Edit the owner, due date and status directly. These changes auto-save.

Evidence & documents
This is a document reference register; uploaded files are not stored in the browser. Use a stable file reference or link. Private evidence storage requires a protected Supabase Storage bucket.
| Title | Site | Type | Reference |

Reporting & export
Export data for Excel, retain a complete backup, or produce a simple printable reporting summary. Measured, forecast and unverified values remain separate.
Audit trail
Records changes to results, targets, actions and evidence. Local mode is not tamper-proof. Production audit requirements need stronger server-side controls.

Online storage & account
Pilot only: connect an administrator-configured Supabase workspace after reviewing the included SQL schema and access controls. Hosting on Cloudflare alone does not provide database storage.
Before connecting
Run the included supabase_schema.sql, create a workspace, add authorised team members, and review its access policies. Do not use production-sensitive information until security and backup testing are complete. The first cloud save requires explicit confirmation to avoid overwriting an existing workspace.
Team editing: Cloud saves currently update a single shared snapshot; simultaneous edits may conflict. Do not use with live multi-user operational data until record-level data handling, role restrictions and security tests are completed.
Emission factor library — administrator setup
The routine calculator uses the applicable factor from this library. Only the diesel candidate is pre-filled. Grid, other fuels, Scope 3 and avoided-emissions factors require CE approval and documented sources. In offline mode this is an administrative demonstration, not an enforced access restriction.
