Life-Areas and How to Estimate Greenhouse Gas Emission Footprints
AbstractTo enjoy a fulfilling life, a person needs six fundamental life requirements to be met. These six requirements or “life-areas” are housing, mobility, consumption of goods (e.g., clothing), diet, other activities (entertainment), and information. In the beginning of this chapter, a top-down estimate of Austrian consumption-based emissions in each life-area is presented. These are organized into segments that may be easily reduced by changing individual behavior and those segments that are fundamental aspects of our society. The remainder of this chapter discusses how to estimate the greenhouse gas (GHG) output. There is a trade-off between accuracy and level of detail, and the need to combine bottom-up survey results with the top-down national emissions inventory. How these trade-offs may be handled is demonstrated using a practical example.
