Green marketing, Eco-friendly Products, Energy conservation, Sustainable development, environmentally safe & Recyclable Products are some of the buzzing words used since last few years. These terms has changed the scenario in society both from customers and producers point of view. Customers feel proud to be called environmentally conscious consumer and producer takes green marketing logo as their enhanced Brand Image. But what is interesting is that the present ecological data does not completely support the above concept. If really companies are more adaptive to environmental standards then why the CO2 emission levels are still above the set bench marks or why there is not any substantial decline in pollution levels. This somewhere indicates that these terms are just used by companies to enhance their brand image thereby selling products in market and their practical implementation is far away from reality. Under the above discussed background this paper attempts to make a critical review of selected cases where companies are making false claims on environmental concerns. This false claim of being Green is called by few Management gurus as Green Washing Concept. Paper tries to lip the second side of Green marketing which is not as rosy as the irst side. Data sourced is mostly secondary in nature with precised justiication. Main suggestions and conclusions are drawn on how society can be immune to false claims made by companies.
