This paper discusses the green practices that can help build the green libraries of a sustainable environment by supporting water conservation and energy conservation, reducing pollution and creating a healthy atmosphere for future generations. Green libraries are built with environment-friendly building materials, which maximize the utilization of locally available materials and natural resources, proper utilisation of waste water and less use of artificial energy by using natural ventilation and renewable solar energy effectively. Library professionals are taking part in going green for sustainable development by taking precautionary measures to decrease global warming, greenhouse gases, and pollution and adhering to green practices for a healthy environment and survival. The study covers the role of librarians in building green libraries and practising green habits in libraries. The steps involved in creating green libraries and the skills that need to be updated and adopted by library professionals are discussed.
