"Surprisingly, the Yellow Pages directories are still being used."
The Yellow Pages brand has accepted that many consumers prefer to use digital services over a book. Due to this they have created an online service which allows consumers to opt out of receiving the books in the future. This of course will will further reduce the levels of paper the company is using.
While the attention their company is giving to their carbon footprint is commendable, they may be better off focusing on their online product. Yellow Pages does have a website however it is not as popular as it could be. With proper advertising and SEO techniques Yellow Pages has the potential to be even more successful.
