Comparative study of greenhouse gas emissions between off-site prefabrication and conventional construction methods: Two case studies of residential projects
TLDR
In this paper, the authors investigated the differences of GHG emissions between prefabrication and conventional construction methods and established a quantitative model using a process-based method, which showed that the semi-prefabrication method produces less GHGs emissions per square meter compared with the conventional construction, with the former producing 336 kg/m2 and the latter generating 368 kg /m2.About:

Embodied carbon mitigation and reduction in the built environment - What does the evidence say?
TL;DR: A systematic review of the available evidence and results reveal that no single mitigation strategy alone seems able to tackle the problem; rather, a pluralistic approach is necessary.

Towards adoption of prefabrication in construction
TL;DR: In this article, a feasibility analysis of prefabrication in construction activities is provided based on a questionnaire survey and a financial analysis is also investigated by a local case study, which shows that wastage generation can be reduced by up to 100% after adopting prefabrics, in which up to 84.7% can be saved.

Assessment of the decrease of CO2 emissions in the construction field through the selection of materials: Practical case study of three houses of low environmental impact
TL;DR: In this paper, a case study of three terraced houses built in Spain, comparing them with a building with similar characteristics but constructed in a conventional way and with no selection of materials, showed the possibility of reducing CO2 emissions up to 30% in the construction phase, through a careful selection of low environmental impact materials.
