One of the megatrends of the 21st century is the unprecedented urbanization of the world’s population. According to the United Nations, more than half of the global population currently live in urban areas, and that number is projected to rise to around two-thirds by 2050.
“In 2050 we’ll have 10 billion people on the planet, and to be able to accommodate that we’ll have to build the equivalent of New York City every month,” says Michael LeMonds, chief sustainability officer for Holcim US, a leading producer of building materials. “The pace is staggering.”
