Bloomberg does it again. Ok, it’s not only our super-hero mayor who is behind NYC’s newest environmental upgrades, but we like to think he had a lot to do with it. Top of the list? One of the nation's oldest suspension bridges - The Brooklyn Bridge - is getting a modern makeover and going green. The famous necklace lights on the bridge will be replaced with energy-efficient bulbs, saving over 134 tons of greenhouse gases annually. Coming soon? The city will replace 25,000 streetlights and start phasing in new hybrid police and fire vehicles. All of the upgrades are gearing the city toward its goal of a 30 percent reduction in greenhouse gases by 2030. If anyone can us get there, it’s Bloomberg.
