Climeworks has raised $31m for its costly technology that sucks CO2 from the atmosphere. The small Swiss firm uses high-tech fans and filters to remove carbon dioxide from the atmosphere at about $600 a tonne, which could help reduce the impact of global warming. Zurich Cantonal Bank were among those investing in the company, which claims to have a long-term "vision" of capturing one percent of CO2 emissions by 2025. However, Climeworks costs remain too high, with Canadian rival Carbon Engineering recently saying it could extract carbon dioxide from the air for as little as $94 a tonne.
