The 21st century has been called the "century of the environment." Neither governments nor individual citizens can any longer assume that social challenges such as pollution, dwindling natural resources and climate change can be set aside for future generations. Strategies for clean and sustainable communities need to be established now, community by community. A dawning era of creativity and innovation in "green technology" (also known as "clean technology") is bringing the promise of a healthier planet (as well as the prospect of growing businesses) that can sustain its health. We have targeted green composites and new systems for CO2 capture and conversion as areas of future growth.
