Metro to slash greenhouse gas in Washington

The Washington Metropolitan Area Transit Authority (Metro) has introduced a five-year Energy Action Plan to reduce energy usage and cut greenhouse gas emissions in the US capital. Once fully implemented, it is expected to net $16 million annually in energy cost savings and another $13 million in savings on operations and maintenance expenses by 2025. The plan is part of a commitment by Metro to invest $65m from its capital budget by 2025 in energy efficiency technology, modernise operations and redu

The Washington Metropolitan Area Transit Authority (Metro) has introduced a five-year Energy Action Plan to reduce energy usage and cut greenhouse gas emissions in the US capital.


Once fully implemented, it is expected to net $16 million annually in energy cost savings and another $13 million in savings on operations and maintenance expenses by 2025.

The plan is part of a commitment by Metro to invest $65m from its capital budget by 2025 in energy efficiency technology, modernise operations and reduce operating costs.

Paul J. Wiedefeld, Metro general manager and chief executive officer, says: “Together with our riders, we are making the right choice for the environment by changing the way we do business through reduced consumption and efficiencies that will generate long-term cost savings."

The programme includes:

  • A Potomac Yard Station designed to be an LEED Certified transit station in the US.
  • A new HQ, located near L'Enfant Plaza, will be designed to LEED platinum standards, the highest level of energy efficiency and green building.
  • An electric bus deployment strategy to pilot and evaluate the use of electric buses in the fleet.


As part of the project, Metro has also launched a sustainability calculator on the Trip Planner at %$Linker: 2 External <?xml version="1.0" encoding="utf-16"?><dictionary /> 0 0 0 link-external wmata.com false https://www.wmata.com/ false false%> which allows users to view information on how much each Metro trip contributes to reducing the region’s carbon footprint.

Metro says its regenerative braking systems on Metro railcars reduces costs by recovering energy from trains as they decelerate and feeding it back into the traction power system. Also, the net-zero water treatment facility in Largo uses gravity-fed treatment tanks and solar panels to provide the energy necessary to treat water from the tunnels and safely return it to the environment, the company adds.

Traffic cones and barrels have traditionally been on the bottom shelf of the road construction and maintenance industry, typically forming visible soft safety barriers for temporary works at a lower cost than concrete alternatives. On both sides of the Atlantic, however, they are fast gaining new roles as instrumented components in advanced construction safety arrays.

    Japan to equip 5G base stations on traffic lights
    The Government of Japan is to install 5G wireless communications base stations on traffic signals nationwide by 2025. A report by The Japan News says the project is expected to reduce costs for telecommunications service providers. As part of the project, traffic signals will be equipped with devices to measure the amount of traffic. The information sent from the stations to the vehicles is expected to support autonomous driving. Japan is not the only company looking to harness the potential of 5G. In F
