Model-driven management of construction carbon footprint
… on developing best practices for reducing the carbon-footprint of the construction phase of the life-cycle of a project has been limited. Although the construction phase is short compared to the use phase of a building, the intensity of emissions during this phase is higher and there is an …

A classification of carbon footprint methods used by companies
The percent increase in greenhouse gas (GHG) concentration in the atmosphere can be harmful to the environment. There is no single preferred method for measuring GHG output. How can a company classify and choose an appropriate method? This thesis offers a classification of current methods used by …

Streamlined carbon footprint computation : case studies in the food industry
One of the greatest barriers in product Carbon Footprinting is the large amount of time and effort required for data collection across the supply chain. Tesco's decision to downsize their carbon footprint project from the original plan of 70,000 house brand products to only a small fraction of them …

An investigation of carbon footprint reductions achievable in Cape Town social housing considering rebound effects
… geysers with SWHs will reduce a household’s carbon footprint. It is also believed that living in a well-located area close to jobs, schools, shops and public transport will reduce a household’s carbon footprint through reducing fuel consumption via private/public transport. These conclusions, …

A Framework for Benchmarking and Monitoring Building Construction Embodied Carbon Footprint using Building Information Models
… exists for suppliers to provide embodied carbon footprint rates, and similarly, for contractors to balance project costs, schedule objectives with the corresponding environmental impact. To address these challenges, we propose and develop a new framework that applies BIM for reliable, …

Assessment of the potential carbon footprint of engineered processes for the mineral carbonation of PGM tailings
Mineral carbonation is a carbon sequestration technology that entails the reaction of CO2 with oxides or silicates of magnesium, calcium or iron to produce stable carbonate compounds. Magnesium-rich tailings from the platinum industry in South Africa have been identified as a potentially viable and …

Measuring supply chain carbon efficiency : a carbon label framework
… change has increased the attention regarding the carbon emissions "embedded" in the products we consume. This increased attention creates a need to measure and improve the carbon efficiency of the supply chains that produce those goods. In this thesis we present a method for measuring the carbon …
