Indian consumers are the most eco- friendly as they have shown increasing environmentally friendly behavior over the past two years, a recently conducted survey has revealed. India scored 62.6 points to hold the top spot, the survey conducted by GlobeScan in 17 countries revealed. The survey analyzed consumer behavior that has an impact on the environment, including their transportation patterns, household energy and resource use and consumption of consumer goods. Brazil secured the second rank (58), while China (57.3) was third in the overall green index. The United States came last with a score of 45. 'Indian consumers' lifestyles are continuing to emerge as the most environmentally sustainable of any of the countries surveyed, ' the Greendex survey said. 'Yet at the same time, Indians are also the most likely to cite the perception that the seriousness of environmental problems is exaggerated as a barrier to action,' it added. Greendex 2010 ranks average consumers in 17 countries according to the environmental impact of their consumption patterns. It is the only survey of its kind in the world. This is the third year the National Geographic has partnered with international polling firm GlobeScan to develop an international research approach to measure and monitor consumer progress towards environmentally sustainable consumption.
