  • The Cradle to cradle design – ending the cradle to grave cycle of manufactured products, by creating products that can be fully reclaimed or re -used.
  • Source reduction -reduction waste and pollution by changing pattern of production and consumption.
  • The Innovation _The technologies alternative.
  • In developing – whether fossil fuel or chemical intensive .
  • In agriculture -that have been demonstrated to damage health and the enivorment.
  • In the viability -the creating is a center of economic activity around technologies and products that benefit the environment, speeding their implementation and creating new careers that truly protect the planet.

Green Tech Subject Areas
