Explanation:

Green marketing refers to the practice of developing and advertising products based on their real or perceived environmental sustainability.  Examples of green marketing include advertising the reduced emissions associated with a product’s manufacturing process, or the use of post-consumer recycled materials for a product's packaging. Some companies also may market themselves as being environmentally-conscious companies by donating a portion of their sales proceeds to environmental initiatives, such as tree planting.

When a company’s green marketing activities are not substantiated by significant investments or operational changes, they may be criticized for false or misleading advertising. This practice is also sometimes referred to as greenwashing.
