Which Scope 1 and Scope 2 sources Avarni can calculate

Avarni calculates an emission when it has two things: a quantity of activity, and an emission factor for that quantity.

Written by Misha Cajic

Avarni calculates an emission when it has two things: a quantity of activity, and an emission factor for that quantity.

The calculation is always the same:

Emission = quantity × emission factor

There is no fixed list of sources that Avarni supports. If you can give Avarni a quantity, and a factor exists for it, Avarni can calculate it. If no factor exists, you can add one.

How your data becomes an emission

There are three ways to get Scope 1 and Scope 2 data into Avarni.

Upload a PDF or an image

Open a Method, select Import, then select PDFs and Images. Avarni reads each invoice and extracts the quantity, the unit, the date and the supplier.

Avarni recognises the invoice layouts of many Australian and New Zealand retailers for electricity, gas, LPG, fuel, water and waste. For a supplier it does not recognise, Avarni uses a general invoice reader. Accuracy is lower in that case.

Check every extracted value in Import Review before you accept it.

Upload a spreadsheet

Open a Method, select Import, then select Spreadsheet.

You build the Method once. The Method sets the scope, the GHG category, the unit type and the rules that choose a factor. After that, you upload a file each period and Avarni applies the same rules.

Use this for any source that does not arrive as an invoice. Refrigerant logs, fleet fuel cards, freight manifests and travel exports all come in this way.

Enter a figure directly

Go to Emissions Hub and select Add emission entry.

You have two options:

  • Calculate based on factor. Enter a quantity and choose a factor. Avarni does the calculation.

  • Directly enter CO2e amount. Enter a figure in kilograms of CO2e that you calculated somewhere else. Avarni stores it as given.

Use direct entry for one-off figures with no underlying data file. Keep your working, because an auditor will ask for it.

Your general ledger

Your ledger can also produce Scope 1 and Scope 2 emissions. Spend classified to a Scope 1 or Scope 2 category by your GL rules calculates in the same way as any other activity.

Spend-based figures are less accurate than meter readings or invoices. Use them only where no better source exists.

Scope 1 categories

Every Scope 1 activity in Avarni belongs to one of four categories.

Category

What it covers

Non-transport combustion

Fuel burned in equipment that does not move. Boilers, furnaces, generators, gas heating.

Transport combustion

Fuel burned in vehicles that you own or lease. Cars, trucks, forklifts, ships, aircraft.

Fugitive

Gases released without combustion. Refrigerant leaks from air conditioning and cold storage, and methane from waste.

Process

Gases released by a chemical or physical reaction, not by burning fuel. Cement clinker, lime, and metal smelting.

You set the category on the Method, or on each emission entry.

You can also select Auto-select. Avarni then takes the category from the factor that it matched. If that factor has no category, Avarni uses the fallback category that you set on the Method.

Scope 2 categories

Scope 2 has two categories. They are two ways to report the same electricity.

Location based

Avarni uses the average emission intensity of the grid that supplies your site.

Your data needs a location. Map a column to Location/Address when you upload. If you do not hold addresses, map Country instead. Avarni then applies a national factor, which is less precise than a state or grid factor.

Market based

Avarni uses the contracts and certificates that you hold.

Avarni supports market based reporting for Australia and New Zealand. It accepts Large-scale Generation Certificates and GreenPower in Australia, and New Zealand Energy Certificates in New Zealand.

Avarni subtracts the certificates that you surrendered from your consumption, applies the published residual mix rate for the reporting year, and calculates emissions on the remainder.

A certificate counts only when its status is Surrendered. A certificate that you hold or sold does not reduce your emissions.

The GHG Protocol asks you to report both figures where a market for contractual instruments exists. Australia and New Zealand both have one.

If no factor exists

Go to Settings, then Emission Factors, then select Add Factor.

You must give:

  • a name

  • a region

  • a year

  • an input unit

  • a CO2 factor, a CH4 factor and an N2O factor

Enter each gas factor in kilograms of that gas per unit entered, not tonnes. Avarni applies the global warming potentials and converts the result to CO2e.

To add many factors at once, select Upload Factors.

Custom factors are private to your organisation. They appear in a factor source named Custom.

Where to go next

For a specific source, read the article for it:

  • Market-based Scope 2 electricity

  • Refrigerants and fugitive emissions

  • Fuel and fleet

  • Freight

  • Business travel

  • Waste

  • Working from home
