The aim is that marketers would supply customers with more information on the green features of the items on sale, which they will then use to make purchase decisions. As a result, corporations will be compelled to manufacture more environmentally friendly products. As a result, businesses have implemented several green marketing tactics to fulfil the expectations of environmentally conscious customers who are aware of what they are buying. Companies that utilise extreme green marketing completely integrate environmental concerns and responsibilities into their operations and handle environmental marketing mix challenges. The purpose of the study is to examine the influence of green marketing mix on customers‟ green purchasing intention with special reference to supermarkets in Chennai.
