# Emissions reference

> Field reference for EnerG GHG scope columns, emission factors, volume contracts, fleet, and fugitive records

Look up the field schemas for EnerG emissions records and dashboards. For concepts, see [Emissions accounting](/products/energ/concepts/emissions-accounting).

<h2 id="scope-columns">
  Scope breakdown columns
</h2>

The scope breakdown tables appear on the [portfolio](/products/energ/analytics/portfolio-emissions-overview) and [building](/products/energ/buildings/emissions-overview) emissions overviews.

| Column group        | Columns                                                                |
| ------------------- | ---------------------------------------------------------------------- |
| Scope 2             | Per-commodity emissions, such as District Steam and Electric (kg CO₂e) |
| Additional Services | Service-type emissions such as Water (kg CO₂e)                         |
| RECs                | REC Retired                                                            |
| Totals              | Total Location Based, Total Market Based                               |

Annual Consumptions mirrors these groups in usage units. Annual Factors shows the intensity factors used, such as kg CO₂e / kWh.

<h2 id="emission-factor-fields">
  Emission factor fields
</h2>

Create factor sets on the [emission factors library](/products/energ/analytics/portfolio-emissions-emission-factors).

| GHG Scope        | Scope the factor applies to                           |
| Service Type     | Commodity the factor converts                         |
| Geography / Grid | Region or grid the factor represents                  |
| Status           | Draft or active. Only active factors apply to reports |
| Documentation    | Supporting evidence files                             |

<h2 id="factor-resolution">
  Factor resolution order
</h2>

EnerG applies the first match in this order for each reading.

| Priority | Source                             | App label examples |
| -------- | ---------------------------------- | ------------------ |
| 1        | Building-specific override         | Override           |
| 2        | Portfolio default                  | Custom             |
| 3        | System library for region and year | Default            |

For how defaults are chosen and how covered load works, see [Emission factors](/products/energ/concepts/emissions-accounting#emission-factors).

<h2 id="factor-sources">
  Default factor sources
</h2>

| Activity                             | Typical system defaults                        |
| ------------------------------------ | ---------------------------------------------- |
| Electricity (location-based)         | EPA eGRID, national inventories, IEA, UK DEFRA |
| Electricity (market-based uncovered) | AIB residual mix (EU) or grid average          |
| Fuels                                | EPA Emission Factors Hub, UK DEFRA             |
| Refrigerants                         | IPCC GWP tables                                |
| Waste                                | EPA WARM, national waste inventories           |
| Water and wastewater                 | Regional models or DEFRA fallback              |
| T\&D losses                          | Regional loss rates × grid factor              |

<h2 id="contract-fields">

| Retirement Status | Allocation and retirement state |
| Documentation     | Supporting files                |

<h2 id="fleet-fields">
  Fleet fields
</h2>

Fleet emissions track Scope 1 mobile combustion on [Fleet emissions](/products/energ/analytics/portfolio-emissions-fleet-emissions).

| Record         | Key fields                                                                         |

| Vehicle        | Name, fuel type, vehicle type, emission factor                                     |
| Mileage record | Vehicle, distance, distance unit, reporting period, emission factor, documentation |

EnerG calculates CO₂e from distance, fuel, and factor automatically.

<h2 id="fugitive-fields">
  Fugitive fields
</h2>

Fugitive emissions track refrigerant loss on [Fugitive emissions](/products/energ/analytics/portfolio-emissions-fugitive-emissions).

| Section           | Key fields                                 |
| ----------------- | ------------------------------------------ |
| Event information | Building, refrigerant, service date        |
| Equipment         | Equipment charged with the refrigerant     |
| Quantities        | Beginning and ending charge, quantity lost |
| Service details   | Service type and provider                  |
| Documentation     | Supporting files                           |

Quantity lost multiplied by refrigerant GWP produces the CO₂e for the event.
