Prioritizing low-carbon materials and reducing material quantities to mitigate embodied GHG emissions in buildings
As regulations for buildings become increasingly stringent, Life Cycle Assessment (LCA) is emerging as a key method of documenting and reducing embodied greenhouse gas emissions (GHGe). Mitigation strategies often focus on optimizing material quantities or substituting conventional materials with low-carbon alternatives. However, these approaches are typically applied in isolation and to specific building components. This study examines which mit…
Embodied climate impacts in urban development
The urgent need to reduce greenhouse gas emissions and the increasing share of embodied carbon in life-cycle impacts underscore the necessity of mitigating construction and demolition impacts to align with the Paris Agreement. Urban planning significantly influences material flows, with a substantial portion of construction occurring in planned urban development areas (UDAs), such as 76% in Copenhagen, Denmark. However, research on UDAs is limite…
Benchmarking Potential Construction Waste Streams and Their Climate Impact
This study investigates how construction waste intensity affects greenhouse gas emissions (GHGe), analyzing data from 345 buildings constructed between 2007 and 2025. Using material waste rates (MWR) from previous cases, it predicts climate impacts based on typical material compositions. MWR reaches up to 25.6% of delivered materials, with packaging materials accounting for as much as 16.7%. These waste intensities feed into life cycle assessment…
GHG emissions from building renovation versus new-build
A variety of life cycle assessment (LCA) calculation methods and rules exist in European countries for building performance evaluation based on new-build. However, the increased focus on the retention and renovation of the existing building stock raises questions about the appropriateness of these the methods and rules when applied to renovation cases. Using a real renovation case, Danish, Finnish and Swedish LCA-based greenhouse gas emissions (G…
Embodied GHG emissions of buildings – The hidden challenge for effective climate change mitigation
Buildings are major sources of greenhouse gas (GHG) emissions and contributors to the climate crisis. To meet climate-change mitigation needs, one must go beyond operational energy consumption and related GHG emissions of buildings and address their full life cycle. This study investigates the global trends of GHG emissions arising across the life cycle of buildings by systematically compiling and analysing more than 650 life cycle assessment (LC…
Carbon budgets for buildings
Target values for creating carbon budgets for buildings are important for developing climate-neutral building stocks. A lack of clarity currently exists for defining carbon budgets for buildings and what constitutes a unit of assessment—particularly the distinction between production- and consumption-based accounting. These different perspectives on the system and the function that is assessed hinder a clear and commonly agreed definition of ‘car…
Comparison of GHG emissions from circular and conventional building components
The concept of circular economy has been introduced as a strategy to reduce the greenhouse gas (GHG) emissions from buildings and mitigate climate change. Although many innovative circular solutions exist, the business model is challenged by a lack of environmental data on the circular solutions, and thus the potential benefits are not verifiable. The study assesses the embodied GHG emissions of five circular building elements/components. Circula…
