Most people agree that, to fight global warming, a number of steps must be taken. At the individual level, less use of cars and airplanes, recycling and protecting the environment are measures that reduce a person's carbon footprint, that is, the amount of carbon dioxide released into the atmosphere due to the actions of each person.
At a broader level, governments are taking steps to limit emissions of carbon dioxide and other greenhouse gases. One of them is the Kyoto Protocol, an agreement between countries to reduce carbon dioxide emissions. Another method is to tax carbon emissions or increase gasoline taxes, so that both people and businesses have more reasons to conserve energy and pollute less.
