“It is a paradoxical that the man who needs the healthy environment the most, is destroying its sanctity and purity for present monetary gains and endanger its own coming generation.”

　Never before in the history, the environmental degradation has drawn such attention of policymakers, academicians and the court, at least in India. A lot of research has been done during the last few years to find out a suitable linkage between economic activities and the environment and a need for new technologies has felt in order to save environment. Because of the rapid industrial growth the most precious heritage of mankind, the natural environment is at stake. Earlier most of the economic activities, development policies were centered towards the motive of benefits or gain, but for the last few years it has been sincerely realized that investment on environmental conservation measures enhance and improve the productivity.

　In 1997, United Nation’s conference on global warming was held in Kyoto for ten days, the climate change meet lay deadlocked, as none was ready to take initiative to check the further damage to planet earth. USA and 37 other industrial nations agreed to binding reduction in their Green House Gas emission by 2012, setting out a target of 5% below 1990 levels.

　The present concern for preservation of environment arises from the hazardous impact on the environment due to human activities. Industrialization pollutes the air by releasing gases, smoke and dust. It pollutes the water by discharging wastes in water bodies. It also causes ruinous effects on forests. The indiscriminate mining in forests has ruined many surrounding forests in Alwar, Makrana, areas of Rajasthan, Dehradun in UP and several other places which has disturbed the natural eco-balance seriously.

　India has been quick to realize that environment needs protection. The government of India for the first time asserted its concern in the fourth five year plan (1969-74). A department of environment was established at the centre in 1980, to act as nodal agency for its protection. The successive plans also emphasized the necessity and importance of environmental protection. In 1982, International Conference on environmental education was held in New Delhi and emphasized the need for a massive programme of environmental education, research and monitoring. The conference specially emphasized that environmental education must start from primary classes.

　The Supreme Court has forced the government to adopt strict vehicular emission norms in cities. The Apex Court has also insisted on the use of preferred technologies and fuels such as CNG for buses and autos, in order to reduce pollution levels. It is a good news that the government has given green signal for the development of Hydrogen fuelled vehicles that have zero pollution capabilities. The focus of present day policies is to use emission free technologies to be useful in preserving the precious natural environment.
