Carbon footprint has become a widely used term and concept in the public debate on responsibility and abatement action against the threat of global climate change. It had a tremendous increase in public appearance over the last few years and is now a buzzword widely used across the media, government and in the business world. "The carbon footprint is a measure of the exclusive total amount of carbon dioxide emissions that is directly and indirectly caused by an activity or is accumulated over the life stages of a product". Until now only little research has been made trying to explore the relation between knowledge industries and their environment implications. Keeping this in view the present study highlights the carbon footprint of knowledge cycle by contemplating the existing literature so that carbon reduction strategies will be employed by the industries associated with it as a part of social responsibility.
