About the Tourism Operator Emissions Calculator

The Great Barrier Reef Marine Park Authority (GBRMPA) is working with industry and local communities to:

  • Provide critical knowledge and information to improve the resilience of the Great Barrier Reef to climate change
  • To raise awareness of climate change and to motivate individuals, communities and industries to take action to reduce their greenhouse gas emissions, and
  • To raise awareness of vulnerability of communities and industries to climate change and support strategies for adaptation.

The Tourism Operator's Emissions Calculator has been developed to assist in the realisation of these objectives.

What is the Scope of the Calculator

The scope of the calculator is up to you.

Depending on your aims for your business you may choose to calculate the carbon footprint for:

  • a particular section of your business;
  • your entire business; or
  • your entire business plus the emissions associated with your employees and customers commuting to and from your place of business.

The Greenhouse Friendly initiative ceased operation on 30 June 2010. Many of the Product and Service providers are now undertaking the transition to the National Carbon Offset Standard (NCOS) Carbon Neutral Program. Organisations are no longer certified under Greenhouse Friendly; products that were produced and certified before 30 June 2010 are still certified and may carry the Greenhouse Friendly logo. For more information on the program transition, see the following newsletters:

Ensure you keep a record of the scope you chose for each auditing period. By doing so, you will be able to understand if any changes to your carbon footprint have been a result of a changed scope or a due to a change in CO2-e emissions.


  • CO2-e or CO2-e: Carbon dioxide equivalency - Carbon dioxide is one of many greenhouse gases which are released into the atmosphere through natural and human activity. Each gas affects the natural cycle in a different way and to a different degree. To simplify this, a Carbon dioxide equivalency (CO2-e) has been calculated for all of the different greenhouse gases. CO2-e factors allow an easy and accurate way of assessing environmental impact from emissions.
  • Mixed Waste: referred to as co-mingled waste in the NGA Factors - is the waste mix remaining after an operator has removed all possible recyclable waste materials. To know the amount of mixed waste generated from you business will require you to understand your waste mix types and volumes.
  • NGA Factors: National Greenhouse Accounts Factors - A workbook maintained by the Department of Climate Change detailing greenhouse gas emission factors. It contains information which is specific to Australia and in some cases, to each state. The National Greenhouse Account Factors are the backbone of the calculations used on this site.
  • Waste mix types: means any of the following - food, paper and paper board, textiles, garden and park, wood and wood waste, sludge, nappies, rubber and leather, concrete, metal, plastic and glass.
  • Municipal Solid Waste: waste which is disposed in landfill of with no attempt to remove possible recyclable materials from it.

Getting Started

Download the instruction manual (PDF 800kb) or follow the simple instructions below.

Terms 1.To begin, please read the Privacy Notice, which contains information about how GBRMPA intends to use the information you enter into this emissions calculator and your privacy rights.

2.Next, register yourself and your organisation.

Ensure you fill in all the mandatory questions which have an asterisk*.

There is also an opportunity to upload a picture or your logo to personalise your reports, although this can be done later.


3.Click on a picture to choose the asset type you would like to report on.

Next give that asset a name to identify it from all you other assets, e.g. 'Main Office' or 'Dive Shop'


4.Using the emission types shown, enter the data relevant for that particular asset in your business.

Leave the input box blank if it is not relevant.

Repeat steps 3 and 4 for all of the assets you are reporting on today.

More can be added later!

Worksheets to help you collate the required information are available here.


5.Using the tabs on the orange side you can review and submit Carbon Emission Reports, view the Factors used to calculate your emissions and see your Emissions Profile.

You can update Passengers numbers and create reports for different periods here too.


6.This calculator has been developed specifically for Tourism Operators.

We are very interested in your thoughts and feedback is valued.
