This article presents the research outcomes published in various scientific journals on problems and solutions of carbon emission from metals process industries. This paper has focused on potential metals process industries, which are associated with economic development and as well as are responsible for a significant amount of carbon emission.To achieve the goals of the study, the methodology has developed for collecting required information from the relevant journals published in the years 1990 to 2019 for supporting to the ongoing global activities in achieving sustainable development and to mitigate climate change effects. The study revealed that the Steel, Aluminium, Copper, Zinc, and Magnesium process industries are the potential Greenhouse Gas emission sources including Carbon-dioxide, Methane, and Nitrogen dioxide gases. The reported carbon concentration in the Atmosphere was 242ppm in 2018, 404ppm in 2017, 365.48ppm in 2000 and 354.19ppm in 1990. However, if this trend continues, the carbon concentration in the air would be 465 ppm in 2050 and about 700 ppm in 2100, which may increase further earth surface temperature from 3.7°C to 7.8°C. At the global level, the estimated carbon emission from manufacturing industries was about 42 percent which was accounted for 21.5Gt in 2018, 19.32Gt in 2017, 13.8Gt in 2015, and 10.5Gt in 2000.It was reported that the relevant stakeholders made required strategies to keep temperature increase well below 2°C with respect to the Pre-industrial level by reducing carbon emission; and in that aspect, the metals processing industries could play a vital role. This study also revealed that nowadays, a few technologies are available and these would be the part of metals processing industries to reduce carbon emission.This study found that the metals process industries indeed are a potential part of the global carbon emission, and contributing to increasing global warming and climate change. The study concludes that this article indeed would be a potential reference for future researches in this the field in developing models for reducing carbon emission from metal process industries toward mitigating climate change effects.
