Environmental technology, or green technology, or clean technology, is the application of environmental science and green chemistry to conserve the natural environment and resources and to curb the negative impacts of human involvement. Scientists continue to search for clean energy alternatives to our current power production methods. Sustainable development is the core of environmental technologies. Some technologies like anaerobic digestion produce renewable energy from waste materials. The worldwide reduction of greenhouse gases depends on the adoption of energy conservation technologies at the industrial level, in addition to clean energy generation. This includes using solar energy, unleaded gasoline, alternative fuel vehicles, as well as plug-in hybrid and hybrid electric vehicles.

Textile and apparel, being labor-intensive industries, have a code of conduct at the workplace that is difficult to overlook. However, the main challenge before the textile production industry is how to produce a product at a competitive price by using an environmentally friendly process and by reducing emissions and pollution treatment costs. The biosphere is under serious pressure, and the impact on its atmosphere, hydrosphere, and lithosphere by human activity cannot be avoided. Man-made activities, such as domestic, industrial, agriculture, shipping, radio-active, aqua-culture wastes, industrial pollutants, mobile combustion, agricultural activities, burning of fuels, ionization radiation, suspended particular matter, and cosmic radiation, have a negative influence on biotic and a-biotic components in different natural ecosystems.
