Environmental life cycle analysis of Qatar's construction industry

The production of waste, the effects of global warming, and embodied energy use are all significantly impacted by the construction industry. The fastest-growing industry in Qatar has been construction over the past two decades, which is predicted to expand by 3.6% in real terms in 2023 after expanding by an estimated 4.7% per year in 2022. From 2024 to 2027, the construction industry is anticipated to grow at an average annual rate of 3.8%, helped along by investments in the housing, oil and gas, industrial, and renewable energy sectors. Qatar has committed to achieving a significant portion of its goal to construct a substantial number of 'green or carbon-neutral' buildings across the Middle East and North Africa (MENA) by the year 2030. If the construction is not monitored and kept under control, it will consume a significant amount of energy and produce waste that will impact the surrounding ecosystem. Life cycle assessment, often known as LCA, has become an essential component in the building industry's push toward green infrastructure design. This is because LCA provides a method that is both objective and reliable for determining the environmental implications of various building techniques, components, and assemblies. Using an approach known as life cycle assessment, the purpose of this study is to determine the environmental impacts that are most significant to construction projects across their full life cycles in Qatar. This study helps identify potential risks and possibilities in the Qatari construction project by conducting a thorough and analytical analysis of the existing literature. The results of this study show that the construction industry has a significant adverse impact on Qatar's environment in terms of energy use, greenhouse gas emissions, and waste generation. According to research, LCA can help identify areas in the construction industry where sustainable practices can be promoted and environmental effects reduced.
