Car Emissions: Recycle Them
While scientists are searching for an auto fuel that does not release dangerous greenhouse gases, other researchers are working on a strategy to capture, store and eventually recycle carbon dioxide from vehicles to prevent the pollutant from finding its way from car tailpipes into the atmosphere.
Technologies to capture carbon dioxide emissions from large-scale sources such as power plants have recently gained some impressive ground, but nearly two-thirds of global carbon emissions are created by much smaller polluters, especially cars and other transportation vehicles.
