Over the several years, population growth, water pollution, air pollution, climate change, and global warming are the most discussing and emerging environmental issues. Greenhouse gas emissions are caused to global warming and it was a serious problem that should be one of the primary challenge for governments. The above mentioned issues are all interrelated to each one. Prevention of CO2 emissions from all sectors is the primary solution of the global warming issue and simultaneously we can control the climate change. In the 21st century, water scacity, water quality and pollution are expected to become more acute as population growth. Currently 600 million people face water scarcity and nearly 3.2 billion people may be living in either water scarce or water stressed conditions by 2025. In developing countries, in many areas are serious contaminated of natural resources and serious effects on human health. The transmission of pathogens through tap water and drinking water remains a significant problem. Worldwide, nearly 10 to 20 million deaths occur a year due to the water borne bacterial pathogens diseases. The other biggest issue is air pollution. Particulate matter is released from various industrial processes via stack emissions to air. Particulate matter can cause long term effects on people’s health and reduce life expectancy, particularly those are suffering with pre-existing heart and lung disease. PM 2.5 is an emerging priority pollutant in global. The solution of this major problems are i. CO2 emissions prevention, ii. CO2 utilization. Accelerated carbonation is a multipurpose technique for water purification, heavy metals stablization which are presented in water, and improving the CO2 capture capacity. CO2 capture, utilization (CCU) is a promising technology where in CO2 is captured and stored in solid form for further utilization instead of being released into the atmosphere. The new advanced process called accelerated carbonation has been widely researched and developed.
