Ever since Al Gore produced “An Inconvenient Truth,” a documentary about the global warming crisis, people have begun to take an interest in this very serious issue. Many people now consider the carbon footprint of items that they purchase. Others buy carbon offsets for vacations that they take. In addition, governments around the world have taken measures to address climate change, including Europe which has implemented a long-term greenhouse gas reduction plan. Despite the fact that very little was accomplished at the climate change conference in Copenhagen in 2009, citizens and governments alike are at least talking about the issue. New climate change legislation is bound to be enacted in the next several years, and there is no doubt that it will have a major impact on how we live our lives.
