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: Mean daily electricity consumption can be estimated based on the number of inhabitants. 

 

Source: CSIRO, 2018

 

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 

Source: City of Melbourne - Transport Strategy 2012 

 

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 

Source: Climate Active Inventory. (The Climate Active Inventory is not publicly available. It’s sent only to registered Climate Active consultants and Climate Active certified groups) 

 

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 

Source: Climate Active Inventory.
