Green marketing involves developing products and services that satisfy customer needs and wants without harming the environment. It provides business benefits like reducing activist pressure, attracting employees, improving community relations, enhancing brand image, and appealing to socially responsible investors. Companies should communicate their genuine environmental efforts and achievements through measurable projects in areas like energy, materials, land use, transportation, water, waste, and air quality using various media channels. However, misleading claims about a company's environmental practices or a product's green benefits are considered "greenwashing."
