The world is going through a very tough situation in terms of environment pollution. Many of the activities of human are creating huge pollution in the entire world. The weather and climate have been changing continuously due to a wide range of human factors. This emission of Greenhouse gases increases the atmospheric temperature gradually. This paper provides a critical perspective to the debate on various greenhouse gas emission in the world. This paper consists of three major areas of discussion. First part of the discussion is with Trends in global CO2 emission second part is global CO2 emission by sector. The last part of the discussion is the potential alternate option to reduce this Gas emission and its concerns for growth focus is discussed for further research. Most of the research papers focused about the solution to the reduction of greenhouse gas emission. Furthermore, in this paper I have focused on the review of Indian wind industries model and its major constraints faced by a wind turbine manufacturer. The result of this research paper is a solid base for further research on which parameter to be focused so that this industry can grow. © (2014) Trans Tech Publications, Switzerland.
