Deutsche Bank has installed an enormous carbon counter, a 70-foot-tall billboard at 33rd Street and 7th Avenue in New York, above Manhattan’s Madison Square Garden. Germany’s largest bank intends to use the counter to promote climate- change awareness and the bank’s research and investment in climate issues. Low-risk carbon credits are used to offset its energy use and 40,960 low-energy light-emitting diodes light up the sign. The actual numbers shown are from Massachusetts Institute of Technology. Deutsche Bank has declared that it will reduce its global carbon emissions by 20 percent annually, with a goal of becoming “carbon-neutral” by 2013.
