Experiments in Reducing Methane Emissions

Researching natural ways to reduce greenhouse gas emissions, Ben Girgenti ’22 MESc tested whether adding minerals to wetland ecosystems can reduce biological methane emissions. After adding iron to the soil of mini wetlands, Girgenti found that methane was reduced by the mineral enhancement.

“If you’re building or using wetlands for natural carbon capture, you could shut off or decrease methane emissions, reducing the amount of time it takes for wetlands to begin having new sequestration of carbon,” Girgenti says.
