CTA, NCTA extend voluntary STB efficiency agreement

The extended agreement is expected to save consumers $1.6 billion in energy costs and avoid 9.3 million metric tons of carbon dioxide (CO2) emissions each year, once the benefits of the agreement’s new commitments are fully realised. That’s the equivalent of avoiding the electricity use of every home in Chicago or the emissions of more than two million passenger cars each year. – Michelle Clancy, Rapid TV News http://ift.tt/2FK32X0
