Sustainable lifestyle through reducing greenhouse gas emission
Assignment 4, worth 20% of the overall subject score
Complete the following tasks:
Calculate the greenhouse gas emissions from the existing household presented below using
Australian Greenhouse Gas Calculator (You should use it in Detailed Version).
Suggest how you can reduce the greenhouse gas emissions from this household to the level
(either below or as close as possible) of a green household's greenhouse gas emission. Provide
Justifications for each of your suggestions. For example, how the proposed solution reduces the
emission? Present the detail calculation where appropriate. Provide reference for each of your
suggested measures or action.
In your report, provide the screenshots of all the inputs in the Australian Greenhouse calculator and
the final report of greenhouse gas emission of the existing house. Then provide the screenshots of all
suggested changes followed by justifications of each suggestion. Then provide the screenshot of the final
report of greenhouse gas emission of the improved house.
