Nigeria Emission Factor Database (NEFDB) is an open, versioned collection of emission factors built specifically for Nigerian grid electricity, fuel combustion, transport, and waste operations. # NEFDB - Nigeria Emission Factor Database NEFDB publishes versioned Scope 1 and Scope 2 emission factors for Nigerian operations. ## What is NEFDB? The Nigeria Emission Factor Database (NEFDB) is an open, versioned collection of emission factors built specifically for Nigerian grid electricity, fuel combustion, transport, and waste operations. Each factor is traceable to source data and calculation notes so the figures can be audited and reproduced. It is designed for: - Researchers studying Nigerian greenhouse gas emissions - Regulators and auditors reviewing corporate carbon disclosures - Sustainability teams preparing reports for NGX, FRC, and SEC Nigeria - Developers building carbon accounting tools for Nigerian companies ## Public datasets All NEFDB source datasets, documents, and derived calculation outputs are published through the public R2 Worker: **`nefdb-r2-publisher.ugbodaga…`** Published domains: | Domain | Worker route | |--------------------|------------------------------------------------------| | Grid electricity | `/grid_electricity/` | | Fuel combustion | `/fuel_combustion/` | | Transport aviation | `/transport_aviation/` | | Waste water | `/waste_water/` | Each domain contains `main`, `additional`, and `derived` folders for datasets and documentation. ## Installation Add the package with Bun, npm, pnpm, or Yarn: ```bash bun add @palmgrove/nefdb ``` ```bash npm install @palmgrove/nefdb ``` ## Usage Import the database API from the package: ```typescript import { nefdb } from "@palmgrove/nefdb"; // List every factor in the current version const all = nefdb.list(); // Include source records const withSources = nefdb.list({ withSource: true }); // Include full factor records const full = nefdb.list({ full: tru …
