The tremendous growth in economic activity across the globe is placing pressure on natural and environmental resources. The rising concern for the environment in response to global warming is driving thinkers to seek sustainable solutions. The real estate industry is a significant contributor to the global warming due to extensive emissions of greenhouse gases (GHGs) from the energy use in buildings. This indicates that there is a real opportunity to develop green buildings in the country. The concept of green building integrates interests and aspects of sustainability emphasising reduction of environmental impacts through a holistic approach to land and building uses and construction strategies. Many professionals associated with the building industry follow different guidelines depending upon the need of the project. A study was done to check awareness and knowledge of contractors in the areas of green buildings and sustainable development. This study was conducted in Delhi-NCR Regions. The methods used for data collection were interview schedule and group discussions. It was revealed that the knowledge of contractors is very low in the areas of green buildings and sustainable development. These findings reveal there is a need of trained professionals for construction of green buildings.
