Earn a doctorate degree in Sustainability, help lead innovation in a growing industry

Tremendous career opportunities exist in multiple government agencies and industries who are reporting significant workforce shortages of technical management personnel with a doctoral degree and experience in sustainability and how to efficiently manage resources. Moreover, the shortage is growing each year. This program is in response to that need. The Ph.D. in Sustainability degree is for new doctoral graduates and non-traditional students (i.e., experienced personnel) who desire to advance in their careers by gaining senior level skills in government and industry related directly and indirectly to sustainability technologies.

Capitol Technology University’s online PhD in Sustainability degree is a unique program designed to meet the long-standing needs of managing our resources efficiently, effectively and with sustainability. This degree is not an environmental science degree or environmental in focus. The focus is technology in using science and technology is reducing resource demand, the reliability of what we use and the engineering to deliver on real improvements. Currently wind turbine blades only are usable for 10 years, then buried until a solution of how to recycle material is not able to be used with current knowledge. Sustainable means designing turbine blades to last considerably longer, using materials that can be recycled and supporting a net zero carbon environment.
