Bonus climate solution: Add wollastonite to green roof and urban agriculture soils

October 30, 2021

In this month’s issue of Environmental Science & Technology three researchers we work closely with at Guelph University, Ontario published an article making the case for carbon sequestration by using wollastonite in rooftop soils everywhere. If all the available urban roof space around the world contained plants and soils with wollastonite, 1% of global carbon dioxide emissions could be sequestered right in cities. Using urban areas to capture large amounts of carbon dioxide is an innovative strategy that creates new carbon capture potential while increasing food production. Read the full article here.
