Building Energy Consumption and Carbon dioxide Emissions: Threat to Climate Change

Climate change has become an undoubted environmental challenge in last couple of decades in every continent and all sectors across the world. It occurs due to increase in temperature of atmosphere by burning of fossil fuels and releasing of greenhouse gases. These days, vast quantities of fossil fuels have been used for energy source to power the economy of a country. This scenario significantly contributes to a large percentage of carbon dioxide emissions. By comparing with other economic sectors, it was reported in the literature that the consumption of energy in buildings accounts for about one third of the total consumption and responsible for an equal portion of carbon dioxide emissions in both developed and developing countries. In order to have a deeper understanding into existing knowledge concerning this area, this paper presents a review on building energy consumption and its related carbon dioxide emissions as threat to climate change.
