Using the Carbon calculator

Our carbon footprint calculator has been developed for people who already understand the concept of carbon footprint measurement and have already used more superficial carbon calculator tools to get a sense of what is involved in measuring your carbon footprint.

Please note that this is a very comprehensive carbon calculator that is intended to give you a high level of accuracy regarding your carbon footprint.

It requires that you have a good sense of the detail related to how you travel, how you manage waste, your energy and water consumption.

What does our Carbon calculator measure?

The following carbon footprint measurements can be ascertained by using this tool:

Getting started

We recommend that you first have a look at the full calculator and decide which aspects of your carbon footprint you would like to measure. Then make notes of the information you need to gather in order to work out your carbon footprint before you sit down to use the tool.

Guidelines for use

If you donít have or donít want to include information on all of the sections, thatís ok Ė you can enter whatever you have to work out the precise carbon footprint of the aspects you choose to focus on.

The on-line calculator has been designed so that you can measure your carbon footprint for a wide spectrum of parameters. For example:

  • You can work out your footprint for any period from 1 day to several years.
  • You can work out the measurement for any number of groups e.g. families, grades, departments, individuals or an entire campus.
  • You can work out your Waste disposal for any weight or volume.
  • You can calculate your travel impacts for any period or distance.

Before sitting down to enter your data, decide what period you will be looking at across all areas. For example it will be possible but may not make sense to work out your monthly transport footprint, your annual waste footprint and your quarterly flight footprint. Ideally you should decide on one time-frame (we recommend bi-annually at least) that you feel comfortable with and that will enable you to manage your own progress.

Before working out your footprint, decide on your parameters - whether your entire school, campus; department or company will participate and then break down the measurements to manageable portions. For example whether to measure the carbon footprint of specific buildings or focus on a specific area e.g. the schoolís water footprint or the transport footprint of each grade. Keep it simple, start small and build on from there.

If you measure more than 1 theme there is a summary sheet which records the findings of each theme being measured and you should complete the full sheet (you can skip over any parts you donít want to enter) before going to the summary sheet to get a sense of your summary carbon footprint.

Project 90 Clubs that compete for prizes for carbon footprint reduction have to record data for similar periods in order to compare progress fairly. Club coordinators will assist Clubs in this regard.

First have a look at the full calculator and decide which aspects of your carbon footprint you want to measure. Keep it simple to begin with.

Make a list of what info you will need to gather in order to work out your carbon footprint accurately before you sit down to use the tool.
