Greenwashing
Noun: Greenwashing is an unsubstantiated claim to deceive consumers into believing that products are environmentally friendly or have a greater positive environmental impact than what is true.
Example 1: An airline claiming it is carbon neutral because it buys carbon credits from existing forests is guilty of greenwashing.
Example 2: Tesla owners are greenwashing if they believe their cars, charged with electricity from fossil fuel powered plants, are good for the environment.
