The process of designing and selling products based on their real or perceived environmental sustainability is known as green marketing. Advertisement of lower emissions connected with a product’s production process or the use of post-consumer recycled materials for a product’s packaging are examples of green marketing. Some businesses may also promote themselves as environmentally responsible by contributing a percentage of their profits to environmental causes such as tree planting. When a company’s green marketing efforts aren’t backed up by major expenditures or operational improvements, they risk being accused of misleading or deceptive advertising. Greenwashing is a term used to describe this behavior.
