This note presents a method to decompose life cycle inventories derived from integrated and mixed-unit hybrid life cycle assessment. The approach extends the decomposition method described by Wiedmann by diferentiating between impacts from industries, products and processes.
The construction industry contributes around 18% of greenhouse gas emissions, 40% of depletion of natural resources, and 25% of wastes globally. To reduce these impacts, construction industries can adopt low-carbon alternatives for construction materials and waste minimisation strategies, including the recycling of construction and demolition waste.
New research shows that 90 megatonnes of greenhouse gas emissions are emitted annually in constructing new buildings and infrastructure and maintaining the existing ones. Reducing this liability of “embodied” emissions will be much harder than building zero-carbon buildings. Here is why.
Concrete is the second most used material after water and the production of cement is responsible for 5–8% of global carbon dioxide emissions. The development of low-carbon concretes is pursued worldwide to help the construction industry make its contribution to decarbonising the built environment and achieving carbon reduction targets agreed under the Paris Climate Agreement.
In order to ensure that the Integrated Carbon Metrics (ICM) project meets industry and user needs, a scoping study was conducted within Australia with construction industry professionals.The aim of the study included the following:Gain an understanding of the construction industry’s current approach to embodied carbon assessment;Identify perceived strengths and weaknesses of current embodied ca
One third of global greenhouse gas emissions are emitted from the building sector contributing significantly to the problem of climate change. While more work has been done on decreasing direct emissions from the operation of buildings, embodied emissions of construction materials receive little consideration even though they constitute a significant additional proportion of emissions.
This project interim report presents the initial outcomes of the research that consist of:
PART 1: Recruitment of participants from single dwellings and multi-unit dwellings, and initial data analysis of the stage 1 survey;
PART 2: Analysis of the BASIX assessment model, key variables and methods of data collection for the stage 2 energy performance monitoring.
