Application of nanotechnology which involves the manipulation of materials at the scale of the nanometer to green engineering principles is "Green nanotechnology".  It also refers to the use of the products of nanotechnology to enhance sustainability. Maintaining and improving soil, water, and air quality represent some of the most formidable challenges facing global society in the 21st century. Pollutants from such diverse sources as oil and chemical spills, pesticide and fertilizer runoff, abandoned industrial and mining sites, and airborne gaseous and particulate matter from automobiles exacerbate the situation on a daily basis. Detecting and treating existing contaminants and preventing new pollution are among the challenges. Application of nano-materials in diverse fields such as enhancing the production and refining of fuels and reduction of emissions from automobiles, energy storage (batteries and nano-enabled fuel cells),to provide safe drinking water through improved water treatment, desalination, nano-enabled insulation and design of nano-materials for pollution sensing and detection.

The total energy-related market for nanotechnologies at nearly $8.8 billion in 2012 and $15 billion in 2017, a five-year compound annual growth rate (CAGR) of 11.4% through 2017.
