While exciting wooden structures are springing up across the world—including fancy wooden skyscrapers from Norway to Milwaukee, Wisconsin—they remain the exception in most countries.
With its sleek expanse of solar panels on the roof along with other energy efficiency measures, it is a carbon-negative building. In other words, from birth to demise, it will have drawn down more carbon than it emitted.
As trees grow, they sequester carbon—about one tonne of CO2 for every cubic meter of wood. While carbon is emitted in processing the wood, the production of concrete is notoriously carbon-intensive. Just the chemical reaction that produces a tonne of cement releases about half a tonne of CO2. Provided the trees come from sustainable forests—so they are replaced when chopped down—and as long as the wood is recycled at the end of a building's life, it could be a powerful solution.
