We have been looking at public worldwide data about CO2 emissions online. This graph shown above is information provided by the world bank and graphically illustrated by google which is free to use. This online tool is useful for the project because it allows us to research the amount of CO2 emissions in any country and compare them to other countries. We can use this data to input into our carbon footprint structure which will give audio feedback to the audience in relation to the data shown above. Data like this will also be used throughout the testing stage to gain an understanding of the public's knowledge about worldwide CO2 emissions.
