In State of the World 2008: Innovations for a Sustainable Economy, researchers with the Worldwatch Institute and other leading experts highlight an array of economic innovations that offer new opportunities for long-term prosperity. For example:
* In 2006, an estimated $52 billion was invested in wind power, biofuels, and other renewable energy sources, up 33 percent from 2005. Preliminary estimates indicate that the figure soared as high as $66 billion in 2007.
* Carbon trading is growing even more explosively, reaching an estimated $30 billion in 2006, nearly triple the amount traded in 2005.
* Innovative companies are revolutionizing industrial production while also saving money: for example, chemical giant DuPont cut its greenhouse gas emissions 72 percent below 1991 levels by 2007, saving $3 billion in the process.
