It's a question that has weighed on the minds of businesses ever since the first evidence of global warming appeared - how important should it be for companies to focus on reducing their carbon footprints?
The debate runs into contentious territory when carbon-reducing measures would be harmful to a business' bottom line. Luckily, one way of going green - video conferencing - is as cost-effective and useful as it is green.
According to GreenBiz.com, Hewlett-Packard's travel costs fell by 43 percent after the company adopted video conferencing technology as way to reduce its carbon footprint. For companies like Hewlett-Packard, whose annual revenues top $1 billion, carbon management has helped reduce a range of long-term business risks that may one day actually threaten their bottom lines - meaning that it may be worth it to invest in green technology today, even if it means slightly slimmer profits for a few years.
Going green by investing in technology such as video conferencing also helps companies protect themselves against energy-supply disruptions.
Some major companies that have gone green include Walmart, which is using solar energy in many of its stores, Verizon, Ikea and Chipotle.
