Preface by Shri Nitin Gadkari (Minister - Road, Transport & Highways, GOI) Faced with increasing environmental challenges, the construction industry is at a crossroads. On the one hand, it is an important engine of economic growth and development, providing shelter, infrastructure, and jobs for billions. On the other hand, it is a major factor in environmental pollution, consuming huge amounts of natural resources and emitting significant greenhouse gases. The need for change is clear and the way forward is sustainable development. The book "Sustainable Construction" is written by accomplished authors like Er. Chirag Baxi and Dr. Snehal Abhyankar aim to illuminate the central role of sustainable building practice in addressing the pressing environmental challenges of our time. Thanks to both and I wish them luck writing more on these topics in the future.
