AbstractAlthough the construction industry has provided societies with facilities and infrastructure projects that meet their needs and fulfill their requirements, created up to 7 % of the world's job opportunities, made around one-tenth of the world's Gross Domestic Product and stimulated growth of other industries, it also, in the other hand, has been proven to have a negative impact on the environment (Mthalane, 2009). The construction industry accounts for 40% of the CO2 emission worldwide, 30% of Raw material usage, 40% of energy consumption and 20% of fresh water consumption (Wilkinson and Reed, 2006).The world's countries have achieved varying levels of success in implementing sustainability in their local construction industries. However, it is still difficult to rank them based on their achievements due to the absence of a clear defined scale that all the countries can be compared to. This thesis develops a new concept called a Mature Sustainability in Construction Industry. It also proposes a Maturity Model that can be used as a scale to evaluate how mature a country is in regard to its sustainability adaption in the local construction industry. The Model is created by studying different maturity models from other industries, and understanding how they define maturity. Furthermore, the thesis proposes a rating system that can determine a country's sustainability level using mathematical equations, and it includes a case study in which the United Arab Emirates is rated in order to show how the rating system works. The input data of the rating system was obtained by conducting a survey on different construction companies and the local public of UAE. The rating example found out that the UAE belongs to level 2, which is the "Satisfactory Level, and a Deviation from the Ideal Mature Level of 2.427.
