As global climate change and the resulting high frequency of natural disasters have become critical world issues, promotion of green, environmentally friendly and sustainable buildings has become an important method to alleviate environmental deterioration, the greenhouse effect and global warming. In 2001, the Executive Yuan formulated and began to implement the Green Building Promotion Program, a mission symbolic of the era. This program aims to achieve the goals of environmental co-existence, co-prosperity and sustainable development by minimizing resource consumption and reducing waste. As a government agency responsible for public works, DORTS is committed to applying this policy to infrastructure design, hoping to serve as a model of promoting energy efficiency and carbon reduction.
