Abstract:

To mitigate climate change and global warming, over 180 countries signed the Paris Agreement to keep the global average temperature no more than 2°C above pre-industrial levels and to aim for the increment to be below 1.5°C. In Hong Kong, the Environmental Protection Department sets the target for reducing carbon dioxide emissions per capita to 3.8 tonnes in 2030 and continues to strive to achieve carbon neutrality before 2050. The construction industry accounts for 36% of total energy usage and 40% of total carbon emissions, and it plays a significant role in sustainability. To enhance sustainability, innovative technologies are adopted for the reduction of energy consumption and fostering environmental friendliness. In this study, different innovative and practical environmental technologies for use in the construction industry are summarised including the venturi cyclone, dewatering bag system, and deodorising sewage tank. It shows that the adoption of innovative technologies is capable of bolstering a friendly working environment and achieving sustainability. This paper is aimed to promote different innovative environmental technologies and encourage the construction industry to spare no effort in utilising new technologies for better sustainability.
