Research confirms that highly manicured lawns produce more greenhouse gases than they soak up. Grass lawns soak up carbon dioxide, which is stored in the soil after the cut grass rots and so, like trees, they are considered good for the planet.
But Dr Chuanhui Gu of Appalachian State University in the US says that once the energy expended by mowing, fertiliser use and watering are taken into account, lawns actually produce more greenhouse gases than they soak up.
