President Donald Trump has proposed to build a new border wall along the U.S. and Mexico border. The proposal has three phases of construction, including fences and walls to cover about 1,250 miles by the end of 2020. About 650 miles of the border has already been fortified. This plan would extend the wall along the rest of the border. The wall is expected to be around 35-55ft high. It is projected to cost around 25 billion dollars. A project of this type, magnitude, and cost requires, at minimum, a screening analysis.
The wall is expected to require a significant amount of concrete. To cover a 1,000 mile wall, about 275 million cubic feet of cement will be needed to form the concrete. This project has been calculated to emit around 1.9 million
