Architects Newspaper: The Latest Architecture and News

This article was originally published by The Architect's Newspaper as "How green are Apple’s carbon-sequestering trees really?"

Apple is planting a forest in Cupertino, California. When the company’s new headquarters is completed later this year, 8,000 trees, transplanted from nurseries around the state of California, will surround the donut-shaped building by Foster + Partners. The trees are meant to beautify Apple’s 176 acres (dubbed Apple Park). But they will also absorb atmospheric carbon.

That’s a good thing. Carbon, in greenhouse gases, is a major cause of global warming. Almost everything humans do, including breathing, releases carbon into the atmosphere. Plants, on the other hand, absorb carbon, turning it into foliage, branches, and roots—a process known as sequestration.

Last week, the Chicago Architecture Biennial opened to over 31,000 visitors and much fanfare, and for good reason - it is the largest architecture event on the continent since the 1893 World's Columbian Exposition, featuring over one hundred exhibitors from over thirty countries. With a theme as ambiguous as "The State of the Art of Architecture," and with the hope of making the biennial, according to directors Joseph Grima and Sarah Herda, "a space for debate, dialog and the production of new ideas," the event was sure to generate equally wide-ranging opinions. Read on to find out what the critics had to say about the Biennial.
