Hamburg’s 1,000th LED traffic light is now operating on the Mundsburger Brücke and is likely to reduce CO2 emissions at the busy crossroads, a press release said Monday. More than half of Hamburg’s 1,720 traffic lights are environment-friendly. The city’s first 40V LED traffic light was built in 2005 and has been refurbished by the Agency of Roads, Bridges and Water (LSBG) in the meantime. This has cut energy consumption by over 6 gigawatt-hours.
Certified green power
Modern LED traffic lights emit 80 per cent less CO2 than ordinary traffic lights with incandescent and halogen lamps. The introduction of sustainable traffic lights in 2005 has cut carbon dioxide emissions by 3,450 tons or the equivalent of CO2 emissions by some 2,400 cars in Germany in the meantime. LSBG hopes to eventually equip all of Hamburg’s traffic lights with the technology and to increase energy efficiency as part of its Climate Protection Master Plan (2013-2020). Since January 2016, all traffic lights and tunnels in Hamburg have been operated on 100 per cent certified green energy from renewable energy sources.
