Things that an individual can do to reduce the chance of climate change:\nMost effective actions.\nSince most of our energy comes from oil, coal and gas, actions that reduce energy use will reduce the emissions of carbon dioxide. For example:\n• When you buy a car, choose one that gets good mileage. \n• Insulate and weatherize your home or apartment. \n• Carpool or drive less. \n• Replace old, worn-out appliances (e.g., refrigerators, heat pumps) with the most efficient new models. If the average U.S. citizen undertakes all of these actions, they can reduce their carbon dioxide emissions by about 25%, which equals about 5 tons of carbon dioxide per year. \nLess effective, but helpful, actions. \n• Turn off lights and appliances when not needed. \n• Plant trees. \n• Set the thermostat lower in winter and higher in summer. \n• Recycle. \nIf the average citizen undertakes all of these actions, they can reduce their carbon dioxide emissions by about 3%, which equals just over half a ton of carbon dioxide per year. \nIneffective actions.\nUsing aerosol spray cans does not cause climate change. In the U.S., they no longer contain CFCs. \nIndividual actions that influence others. Become informed and help your family and friends to learn about climate change. Actively support the government policies you decide are most appropriate.
