SIEMENS

Transportation accounts for approximately 14 % of the world's total annual greenhouse gas emissions — and a considerable amount of vehicle emissions is caused by traffic congestion. Traffic jams in the U.S. alone, for example, generate approximately 25 mill. t of carbon dioxide emissions each year.
Advanced transportation solutions can provide relief — and Siemens' Mobility Division is one of the market leaders for such solutions in the United States.
Over the past few years, the company has repeatedly demonstrated the benefits offered by efficient, local public-transport networks — and today, one out of every three trams and light-rail systems in North America is built by Siemens. Cities including Los Angeles, San Diego, Houston, and Denver use light-rail systems from Siemens, which helps to get cars off the streets while also reducing the burden on the environment.
Such systems, however, represent only one of several options available for significantly reducing road traffic. The Mobility Division's long-term goal in the U.S. is therefore to pool and effectively utilize all traffic-related information. The first step here has already been taken, with one of every six cities in the U.S. already using a traffic guidance system from Siemens. In the future, transport by car and train will be more effectively aligned with one another through the use of additional solutions, such as public transportation information systems, all of which will help to further reduce CO₂ emissions.
