At present, global warming is the most important environmental issue. In industrial development, the excessive use of high-carbon energy has hastened environmental degradation creating a significant greenhouse effect.
A low-carbon economy refers to an economy that causes low levels of greenhouse gas emissions and absorbs as much gases as it releases. Shifting to a low carbon economy not only helps reduce pollution but also has many economical benefits.
As an economy turns into a low-carbon economy, the risks of climate change are reduced as there is less emission of greenhouse gases. There is a shift from non- renewable to renewable sources of energy production, thus increasing our energy security. The environmental degradation also slows down improving living conditions and overall air quality. The overall waste production also reduces significantly.
Also the shift helps in boosting economic growth due to investments and creation of quality jobs in new sectors like electric vehicles, green hydrogen, renewable energy, etc. The step towards sustainable development improves public health, reduces carbon footprint of organisations and also helps achieve Sustainable Development Goals set by nations.
Thus a low-carbon economy not only has environmental but also economic benefits for the country.

Nanotechnology significantly enhances water purification and filtration through advanced materials and innovative processes. Nanoparticles like silver and titanium dioxide possess antimicrobial properties, effectively eliminating bacteria and viruses. Carbon nanotubes (CNTs) offer large surface areas and strong adsorption capabilities, efficiently removing heavy metals and organic pollutants.
Nanomembranes, with precise pore sizes, selectively filter contaminants while retaining beneficial minerals and providing high permeability for faster filtration rates and reduced energy consumption. Nanostructured materials such as graphene oxide enhance the adsorption of pollutants like arsenic and fluoride, while magnetic nanoparticles facilitate easy removal of contaminants using magnetic fields.
Nanocatalysts, including titanium dioxide, enable photocatalytic degradation of organic pollutants and pathogens under light. Nano-enhanced membranes in desalination improve salt rejection rates and water flux, making the process more efficient and cost-effective.
Combining nanotechnology with existing methods, like hybrid nanofiltration systems, enhances performance and reliability. Moreover, nano-enhanced materials lower the energy required for water treatment, promoting sustainability. These advancements offer scalable, affordable solutions for clean water access, benefiting both developed and resource-limited regions.
