+# National Greenhouse Accounts Factors 2024 (Australia)
+
+This dataset contains Australian greenhouse gas emission factors for electricity and gas consumption, structured in JSON format for easy programmatic access. The data is derived from the official Australian Government publication.
+
+## Dataset Description
+
+The dataset includes emission factors used to calculate greenhouse gas emissions from:
+- **Electricity consumption** by state/territory (Scope 2 and Scope 3)
+- **Gas consumption** by state/territory (Scope 1 and Scope 3)
+
+These factors are essential for organizations conducting greenhouse gas accounting in accordance with Australian standards and the National Greenhouse and Energy Reporting (NGER) scheme.
+
+## Data Structure
+
+### Electricity Factors
+- **ef2_kg_per_kwh**: Scope 2 emission factor (kg CO2-e per kWh)
+- **ef3_kg_per_kwh**: Scope 3 emission factor (kg CO2-e per kWh)
+
+Available for:
+- New South Wales & ACT
+- Victoria
+- Queensland
+- South Australia
+- Western Australia (SWIS and NWIS)
+- Tasmania
+- Northern Territory (DKIS)
+- National Average
+
+### Gas Factors
+- **scope1_combined_kg_per_gj**: Combined Scope 1 emission factor (kg CO2-e per GJ)
+- **scope3_kg_per_gj**: Scope 3 emission factors by metro/non-metro regions (kg CO2-e per GJ)
+
+Available for all Australian states and territories with metro/non-metro distinctions where applicable.
+
+## Usage Example
+
+```python
+import json
+from datasets import load_dataset
+
+# Load via Hugging Face datasets
+dataset = load_dataset("your-username/national-greenhouse-accounts-factors-2024")
+
+# Or load JSON directly
+with open('emissions_factors_nga_2024.json', 'r') as f:
+    factors = json.load(f)
+
+# Get electricity emission factor for NSW
+nsw_scope2 = factors['electricity']['states']['New South Wales & ACT']['ef2_kg_per_kwh']
+print(f"NSW Scope 2 electricity factor: {nsw_scope2} kg CO2-e/kWh")
+
+# Get gas emission factor for Victoria metro
+vic_gas_scope3 = factors['gas']['states']['Victoria']['scope3_kg_per_gj']['metro']
+print(f"Victoria metro gas Scope 3 factor: {vic_gas_scope3} kg CO2-e/GJ")
+```
+
+## Data Quality and Verification
+
+- **Accurate**: Values extracted directly from official government publication
+- **Structured**: Organized in logical JSON hierarchy for easy access
+- **Complete**: Includes all emission factors from the 2024 publication
+- **Unmodified**: Original values preserved exactly as published
