This document discusses the history and strategies of sustainable construction. It begins by describing how environmental protests in the 1990s prompted construction companies like Carillion to address their environmental impacts. Guidelines for sustainable development were then established through initiatives like the Rio Earth Summit and the UK government's strategy. This included objectives around resource use, environmental protection, economic growth, and social progress. Construction strategies were subsequently developed focusing on cost savings, environmental performance over the lifecycle, and social benefits. Business benefits of sustainable construction include reduced costs and risk, improved relationships, and employee motivation. Training and cultural change are important for effective implementation.
