Climate change: The craft brewery using algae to cut emissions

Fermenting beer produces carbon dioxide (CO2), which is usually released into the atmosphere. So a craft brewery in Sydney, Young Henrys, has partnered with climate change scientists and developed a way to use microalgae to capture that CO2, and turn it into oxygen.

The brewers estimate their algae releases as much oxygen as two hectares of bushland.
