Climate change poses increasingly demanding challenges for architects. Construction is one of the most polluting sectors on the planet: according to the UN, it consumes 32% of the world's energy and produces 34% of greenhouse gas emissions. The sector responded to these figures with strategies to reduce emissions, with last year being the first year since 2020 in which emissions stopped growing. But now we must take a step forward, and architect and engineer Carlo Ratti, director of the upcoming Venice Architecture Biennale, argues that it is no longer enough for architecture to contribute to the "mitigation" of emissions; he is now talking about "adaptation," that is, "helping our built environments."
