Like you go to Marriott hotels, low and behold there is a sign on the bathroom towel that says "Please help save the planet" by reusing the towel. Sure it helps, but that's not the reason why they put that sign up. It is to save costs of laundry. If they really want to save the planet, how about cutting down private jets for their executives?
It never feels genuine and unless the product/service is directly contributing help to the environment - like an advertisement for a Solar panel company or a Wind Turbine brochure.

"Greenwashing efforts can range from changing the name or label of a product to evoke the natural environment on a product containing harmful chemicals to multimillion-dollar marketing campaigns portraying highly polluting energy companies as eco-friendly. Greenwashing is therefore a "mask" used to cover-up unsustainable corporate agendas and policies."
If private jets are taxed appropriately they'd cost the company more and they'd reevaluate their use too.
