Organisational obstacles to reducing carbon emissions in Hong Kong

What leads to low-carbon buildings? A China study

“…The macro-level management is one of the most influential factors for carbon emission reduction of buildings [34]. Indeed, the decarburization presents significant challenges to governments on related policies and regulations [35][36][37][38][39][40].…”

“…An accurate assessment of the carbon emissions of construction materials will facilitate its selection process via dioxide carbon labeling [34]. Similarly, Conejos et al highlighted the importance of theories of building adaptive reuse in mitigating carbon emissions and climate change [51].…”

“…Reluctance in using low carbon dioxide materials and the lack of environmental awareness hinder the dioxide carbon labeling of materials and consequently the development of low-carbon buildings [34]. Therefore, it is essential to strengthen the education on environmental sustainability and low carbon building [55].…”

BIM-aided variable fuzzy multi-criteria decision making of low-carbon building measures selection

“…There has been a transition of the built environment towards low carbon and increasing attention to the use of low carbon technologies [1,2]. The construction industry is a key sector expected to support achieving carbon emission reductions, as 33% of greenhouse gas (GHG) emissions, 40% of energy consumption and 36% of energy related carbon emissions are concerned with buildings [3].…”

“…The construction industry is a key sector expected to support achieving carbon emission reductions, as 33% of greenhouse gas (GHG) emissions, 40% of energy consumption and 36% of energy related carbon emissions are concerned with buildings [3]. Also, GHG emissions from buildings in cities are even more serious due to high urban density [1]. For instance, in the high-density subtropical urban environment of Hong Kong, buildings" contributions to electricity consumptions and GHG emissions are around 90% and 60%, respectively [4].…”
