Carbon Calculator resources

The results from the carbon calculator are estimates only based on the information when answering questions, and from benchmark assumptions found below.

Electricity

Where is your home? 

Calculations The response can be used to estimate the Full Cycle emission factor based on the location.  

Emissions = Total electricity consumption [kWh] x Full Cycle (Scope 2 and 3 emission factor) [kg per t.CO2]

Source National Greenhouse Accounts Factors, 2021

How many people live at home? 

Calculations The mean daily electricity consumption can be estimated based on the number of inhabitants.

Travel

How many km do you travel by car per week?

Calculations Kg CO2/km = (km travelled per week*52 weeks per year )* Medium car: Unknown Fuel(*) Emission Factor

Source Australian Bureau of Statistics, 2021

How many hours a week do you use public transport?

Calculations Kg CO2/person/km = Distance travelled per hour (km/h) *Hours per week * 52 weeks a year *  Number of persons * Emission factor for transport mode

How many short-distance round-trip flights do you take in a year (up to 2.5h flight)?

Calculations Emissions from short-distance flights (kgCO2)= Number of short-distance flights per year * 2.5 hours * 842km/h * Short-distance flights emission factor (kgCO2/km)

Source Executive Flyers, 2022

How many intercontinental round-trip flights do you take in a year?

Calculations Emissions from long-distance flights (kgCO2)= Number of long-distance flights per year * 14.8 hours * 900km/h * Long-distance flights emission factor (kgCO2/km)

Source Executive Flyers, 2022

Lifestyle

How often do you eat meat and fish during the week?

Calculations Emissions from Meat and Fish (kgCO2)= Quantity of meat consumed per week (kg) * 52 * Average EF

How much do you spend on furniture and furnishings on average each year?

Calculations Emissions from Furniture (kgCO2)= $ spent per year on Furniture ($) * Furniture EF

Source Climate Active Inventory.

How much do you spend on clothing on average each year?

Calculations Emissions from Clothes (kgCO2)= $ spent per year on Clothes ($) * Clothes EF

Source Climate Active Inventory.

How much do you spend on average each year on household appliances and electronic devises?

Calculations Emissions from Technology (kgCO2)= $ spent per year on Technology ($) * Technology EF
