It is an oft-quoted—and always alarming—statistic that 34 percent of the world’s carbon emissions are caused by the construction industry, with a significant portion borne specifically from the production of concrete required to erect a standard structure today. At the same time, we are facing a global housing crisis, as a large population of people moves from rural towns into cities, outpacing the number of affordable, high-quality units being built to accommodate them.

So how does one put these two crises in alignment? Around the world, innovative architects, scientists, and engineers are exploring building techniques and materials that can create places to live without hastening climate change. The secret? Keeping it local.

The concept of embodied carbon—the emissions released across the lifespan of a material, from extraction, manufacturing, and transportation down to disposal—dictates that the most sustainable architecture is built from its surroundings. Forward-thinking minds are tapping both high- and low-tech building methods and materials in every region of the world. From solar-powered pods that can handle the most extreme weather on Earth to residences built, literally, from the earth that surrounds them, each project presents a solution specific to its site, culture, and vernacular—but that can potentially be adapted for use in farflung places.

The design lessons that can be gleaned from all the examples below are found in their commitment to both planet and people.
