Machine to machine (M2M) communication -- whereby sensors and networks allow all the parts of a physical system to communicate directly with each other -- will radically change the way we work, live and travel. M2M will allow us to do more with less, but only if the industry can overcome current market barriers, according to an AT&T-sponsored report published today by Carbon War Room.The potential for M2M technologies to drastically change the way we do business, streamline operations and curb our environmental impacts is evident, but there are significant market barriers that must be addressed to realize the full scalability of these technologies."We've seen the great potential in this technology and made aggressive investments to capitalize on that potential," said John Schulz, Director of Sustainability at AT&T. "We pursued this work with Carbon War Room to tap into their expertise to understand the relationship between this revenue opportunity and potential environmental benefits. This study looks into ways that we can scale that expected huge adoption curve to achieve the benefits faster."In the report Carbon War Room proposes strategies for M2M technologies industry to transform key sectors and reduce greenhouse gas emissions by 9 billion tons. It also identifies the challenges that threaten the industry from reaching its full potential, and offers solutions for overcoming them.
