MITIGATING CLIMATE CHANGE THROUGH GREEN ROOF IMPLEMENTATION: A REVIEW OF SIGNIFICANT LITERATURE

Abstract

Climate change is a threat to the world. Problems resulting from climate change such as global warming, floods, environmental pollution, high carbon dioxide emissions, and loss of biodiversity may be solved by the implementation of green roofs. Green roof benefits the environment, economy, aesthetics, and recreation and are proven effective through studies conducted from around the world. This paper reviews the existing literature on green roof benefits and performance and specifically focuses on their potential to address climate change issues. A review of significant literature on green roof performance and benefits is the method of this study. From the review, it is proven that green roofs have the potential to reduce problems related to climate change. The depth of a green roof substrate is a key factor that can optimize potential benefits. Thus, intensive types of green roofs provide significant contribution towards reducing storm water runoff; mitigate the urban heat island effect and pollution; increased biodiversity; and carbon sequestration. Local research is highly encouraged in mitigating climate change because the optimal performance of green roofs is subject to local climate and conditions.
