Research and development on Green Chemistry, Green Engineering, and Green Technologies (GCET) are at the forefront of recent efforts to address and solve complex issues related to sustainable development. Nanomaterials offer solutions to many global problems; however, their development and implementation have been largely from outside the field of green chemistry and sustainability, with processes, products, and waste which are toxic, nonrenewable, and unsustainable. These do not fit into a global sustainable development framework. The development of green processes and products is vital to mitigating health and environmental hazards. Additionally, educating the next generation of scientists and engineers in the application of green chemistry, engineering, and technology, as well as the development of sustainable nanomaterials, requires new approaches, knowledge, and tools. This special issue focusing on GCET will accept research and educational articles as well as review papers on the following thematic areas.

Potential topics include but are not limited to the following:

• The applications of nanomaterials in sensing and analysis
• Use of nanomaterials in energy harvesting, storage, and conversion
• Carbon capture and sequestration utilizing nanomaterials
• Environmental (water and air) remediation
