 In the book, Gingrich presented his policies for a market-based approach to environmentalism that incentivizes conservation and green technology, rather than relying on regulations or litigation.In particular, Gingrich has proposed using monetary prizes and tax incentives to spur environmentally friendly innovations, such as hydrogen engines, 100-mile-per-gallon conventional fuel engines and ethanol fuels that do not rely on corn or cane sugar.In January 2011, Gingrich proposed the Environmental Protection Agency be replaced with a new organization called the Environmental Solutions Agency, which would be "dedicated to bringing together science, technology, entrepreneurs, incentives and local creativity to create a cleaner environment through smarter regulation".
