The term "green marketing" was originally used in the 1980s. Green marketing has received increased attention from industrialists and customers as a result of climate change, growing globalization, and industrialization. New studies show that corporations are more aware of their responsibility to the community. They recognize that embracing social responsibility is a smart business move that will boost their standing with clients. As consumers' environmental concerns increase, they are shifting their perspective on companies who promote or sell "green" policies and goods including those that use less energy (energy efficiency), organic foods, lead-free paints, recyclable papers, phosphate-free detergents, and energy-efficient appliances. This article seeks to explore why certain customers choose green marketing methods and products over others. Primary data were collected via the use of a standardized questionnaire administered to the sample respondents. The statistical data suggested a substantial correlation between customer perception, green consumer values, and product aspects in marketing tactics. According to the research, customer purchasing behaviour is significantly impacted by their level of consumer knowledge of green marketing.
