This review article discusses the role of policy and regulation in promoting green buildings. Green buildings are essential for sustainable development as they reduce energy consumption, minimize environmental impact, and improve occupant health and well-being. Government policies and regulations play a crucial role in shaping the adoption of green building practices. Through mandates, incentives, and standards, governments can encourage the construction and renovation of buildings that prioritize energy efficiency, water conservation, and environmental sustainability. Mandatory building codes and standards are among the most effective tools governments use to promote green buildings. These codes set minimum requirements for energy performance, water efficiency, and indoor environmental quality, ensuring that new constructions and major renovations meet established sustainability criteria. In addition to mandatory standards, governments also use financial incentives to encourage green building practices, such as tax credits, grants, or subsidies for building owners and developers who incorporate sustainable design features or achieve green building certifications. Government procurement policies can also drive the adoption of green buildings by requiring that public buildings meet certain green building standards or certifications. This creates a market for green building practices and technologies. Public awareness and education campaigns are also essential in promoting green buildings, as they help educate the public about the benefits of sustainable building practices. Monitoring and enforcement are critical components of promoting green buildings, ensuring that sustainable building practices are followed. International cooperation and collaboration are also essential for advancing green building practices and promoting sustainable development worldwide. By setting clear standards, providing incentives, and leading by example, governments can create an environment where green buildings are the norm rather than the exception, leading to a more sustainable built environment for future generations.This review article discusses the role of policy and regulation in promoting green buildings.
