Globally, the significance of embodied carbon (EC) and greenhouse gases (GHG) has been acknowledged due to the increased risk of catastrophic climate change. The temperature rise had already reached 1 ℃ in 2017 due to the rising atmospheric CO2 concentration, and it is predicted to increase by 1.5 ℃ in the coming decades. In order to reduce greenhouse gas (GHG) emissions, the Paris Agreement on Climate Change asks for immediate transformational actions. The built environment sector produces around 40% of energy-related global greenhouse gas (GHG) emissions. To meet the global agenda of reducing GHG emissions, decarbonization of the building and construction sector is critical. This study aims to present the key concepts needed for the reduction of CO2 in moving towards net zero carbon emissions. Despite the widespread use of the term net zero carbon emissions, the process of achieving it remains unclear. This study seeks to describe the factors and strategies that should be considered to help the process.
