BERLIN—The northern German city of Hamburg has become the first in the nation to field a fleet of environmentally-friendly taxis that run on a hybrid electric or natural gas motors that produce fewer environmentally damaging gases.
Under the program, taxi companies that can prove their vehicles meet the low-emissions standards are allowed to brand their cars "Eco Taxis."
Hamburg authorities said the first 130 of the "Eco Taxis" hit the streets on Monday. The vehicles emit some 3.6 tons fewer CO2 emissions compared with a normal taxi each year.
The city says Stockholm has a similar program.
Germany is one of the world's leading carbon polluters. Last year saw an 8.4 percent reduction in carbon emissions.
