Three Pillars of Sustainability

Sustainability seeks to develop and implement the methods and behaviors that balance the consumption of resources with the impact of that consumption on the environment—in an economically viable manner and one that enhances the quality of life. At Parsons, striving for this balance has been made an integral part of everything we do. To be effective, all of our efforts must integrate the three pillars, or dimensions, of sustainability—environmental/energy, sociocultural, and economic:


  • Lessen adverse impact to the environment
  • Conservation of nonrenewable resources
  • Integration of alternative energy sources
  • Lower carbon footprint
  • Use of recycled/reused materials


  • Healthy and clean environment
  • Enhanced quality of life
  • Access to clean water and clean energy
  • Development in harmony with culture and available resources


  • Positive or neutral return on investment
  • Enhances economic development of the community
  • No adverse impact to economies
  • Opportunities for local, small, and disadvantaged business participation
