A new study in Applied Geochemistry explores how green clay tennis courts, common in the US, act as passive carbon sinks. Unlike red clay, these courts use crushed silicate rocks that react with water and air to pull carbon dioxide from the atmosphere through a process called enhanced rock weathering. While the total carbon removal from tennis courts is small compared to global emissions, the research highlights the potential for integrating carbon capture into existing infrastructure. It suggests that scaling similar rock-weathering techniques in agriculture and urban planning could provide a meaningful suite of solutions for climate mitigation.
