Emission Data

The largest module in Slate, 34 activity categories covering everything from a boiler burning diesel to a forest stand absorbing carbon. Here is every one of them, and how to work with the module day to day.

The four tabs

Emission Data for entering and reviewing activity records, Calculated for results (see Calculated Emissions & Errors), Category for a source-by-source breakdown, and Charts for the visual view.

Adding a record

  1. 1

    Open Add Activity

    On the Emission Data tab, use the Add Activity menu to pick one of the 34 categories below.

  2. 2

    Fill in the category-specific fields

    Each category opens its own form, a litre of diesel and a percentage of managed grazing land need genuinely different inputs, not a generic "quantity" box.

  3. 3

    Set Facility and Reporting Year

    Every form ends with the same two fields, which analysis period and site the record belongs to.

  4. 4

    Or upload in bulk instead

    For many records at once, use the Emission template under Upload Sources rather than adding them one by one, see Uploading Data.

Combustion & direct operations

  • Stationary Combustion

    Fuel burned in fixed equipment, boilers, furnaces, generators.

  • Mobile Emission

    Fuel burned in company vehicles and mobile machinery, by fuel used or distance driven.

  • Fugitive Emission

    Refrigerant and gas leaks, five approaches from direct inventory to a screening estimate.

  • Fugitive Emissions, Coal Mining

    Methane released from coal mining, by gassiness category and coal produced.

  • Fugitive Emissions, Oil & Natural Gas

    Venting, flaring and leakage across oil and gas operations.

  • Operated Landfill (SWDS)

    Methane from a landfill your organisation operates, modelled from its disposal history.

Industrial processes

  • Mineral Process

    Process CO2 from cement, lime, glass and other carbonate use.

  • Chemical Process

    Chemical industry process emissions, ammonia, soda ash, ethylene and more.

  • Metal Process

    Iron, steel and other metal production process emissions.

  • Electronics Process

    Fluorinated-gas emissions from semiconductor and electronics manufacture.

  • ODS Substitutes

    Substitutes for ozone-depleting substances in foam, aerosols, solvents and fire protection.

  • Other Product Use

    SF6 in electrical equipment, and N2O in medical and propellant use.

  • Non-Energy Product Use

    Fuel used as a product rather than burned, lubricants, waxes, bitumen, solvents.

Agriculture

  • Livestock, Enteric Fermentation

    Methane from digestion in livestock, by category and population.

  • Livestock, Manure Management

    Emissions from how manure is stored and treated.

  • Lime & Urea Application

    CO2 from lime and urea applied to agricultural soils.

  • Managed Soils, Nitrous Oxide

    N2O from nitrogen applied to soils, grazing deposits, and drained organic soils.

  • Peat Extraction

    CO2 and N2O from peat extraction, by climate zone and area.

Land use & carbon removals

  • Forest Land Carbon

    Growth and removals on forest stands you've set up in Reporting Assets.

  • Settlement Trees

    Biomass carbon in trees within settlement areas.

  • Land Use Conversion

    The one-off biomass carbon change when land is converted from one use to another.

  • Flooded Land

    Biomass carbon lost when land is flooded.

  • Harvested Wood Products

    The carbon pool in wood products leaving your operations, tracked by inflow year.

  • Land Carbon Stock

    Carbon stock change on a land parcel, tracked over a transition period.

  • Biological Treatment of Waste

    On-site composting or anaerobic digestion.

  • Waste Incineration

    On-site incineration or open burning, including the biogenic/fossil split for municipal waste.

Business travel & value chain

These are the Scope 3 categories, emissions that happen outside your direct operations but are still part of your footprint.

  • Business Travel

    Flights, hotel stays and rail travel, with an optional radiative forcing adjustment for flights.

  • Freighting Goods

    Goods moved by a third party, by distance and, where relevant, weight carried.

  • Managed Assets

    Leased or operated vehicles not owned by your organisation.

  • Hotel Stay

    Hotel nights, by country and room count.

  • Homeworking

    Employees working from home, by FTE count and hours.

  • Material Use

    Materials purchased by weight.

  • Purchased Goods & Services (Spend-Based)

    Goods and services estimated from amount spent, when weight or unit data isn't available.

  • Waste Disposal

    Waste sent for third-party treatment (a value-chain view, distinct from the Waste Data module).

  • Water Supply

    Mains water delivered to your operations.

  • Water Treatment

    Water returned to the sewer for treatment.

Running a calculation

Use Calculate Emission from the toolbar. This runs as a background job, a status toast confirms it has started, and a second toast confirms success or tells you what failed.

Note

A record that fails to calculate stays visible with an error reason attached, rather than disappearing from your totals. Click its error icon in the Calculated tab to see exactly what went wrong and how to fix it.
