This week we interviewed Frank Gehry about his Luma Arles tower In an exclusive interview with Dezeen, the 92-year-old Canadian-American architect said The Tower responds to concerns about the carbon footprint of architecture. "We fit into it," he said. "But I can't explain it. I respond to every fucking detail of the time we're in with the people we live with, in this place." Baan's photos show the distinctive stainless steel tower rising above the Luma Arles arts campus in the town of Arles. We continued our carbon revolution series with a pair of stories focused on hemp, which can capture atmospheric carbon twice as effectively as forests, according to Cambridge University researcher Darshil Shah.
