The U.S. government designed TIGER grants in order to incentivize bettering environmental problems and reducing the United States' dependence on energy. On the economic front, the United States hopes infrastructure investment will encourage job creation, a pressing political priority; this would likely require the project to be shovel-ready.
By the end of the 20th century, ecology, energy conservation and sustainable development had become important issues of construction. Construction methods prioritize sustainability and the Leadership in Energy and Environmental Design (LEED) certification was created.
A related concept is that of sustainable development, and the terms are often used to mean the same thing. [6] UNESCO distinguishes the two like this: "Sustainability is often thought of as a long-term goal (i.e. a more sustainable world), while sustainable development refers to the many processes and pathways to achieve it."
