Decomposition of integrated hybrid life cycle inventories by origin and final-stage inputs

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 method can be used to quantify the...

Mixed-unit hybrid life cycle assessment applied to the recycling of construction materials

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...

Modeling the carbon budget of the Australian electricity sector's transition to renewable energy

We report on the carbon footprint of 22 scenario pathways for the transition of the Australian electricity sector to predominantly renewable energy (RE). The analysis employs a dynamic and discrete numerical model that takes into account what we have termed renewable energy ‘breeding’, i.e. RE...

The Australian industrial ecology virtual laboratory and multi-scale assessment of buildings and construction

As global population and urbanization increase, so do the direct and indirect environmental impacts of construction around the world. Low-impact products, buildings, precincts and cities are needed to mitigate the effects of building construction and use. Analysis of embodied energy and greenhouse gas (GHG) emissions...

Global warming impact of suburbanization: the case of Sydney

Suburbs have naturally become a focal point of carbon mitigation for cities undergoing rapid suburbanization. This has created a debate over which urban form can more effectively lead to lower household carbon footprints (CF). Previous suburban-scale studies using economic input-output life cycle assessment with national...
