Berlin, 37% forest, parks, and water

"Berlin is also one of the world’s greenest cities, with parks, forests and water covering 37 percent of the city’s territory. One of the most famous parks, the Tempelhofer Feld, used to be the city’s airport and now is a green space nearly as large as New York City’s Central Park. Berlin’s numerous lakes, rivers and canals are popular recreational spots for residents and tourists alike. The importance to find a sustainable balance between economic prosperity and ecological aspects is reflected in the government’s political endeavours. By 2050, the City aims to be climate-neutral . . . Public institutions serve as role models and are slated to become carbon-neutral by 2030 . . . Addtionally by 2030, Berlin’s public transportation company BVG will only deploy electric buses . . . [and it's] ambitious Solar City strategy seeks to increase the share of solar power generation to 25 percent of the city’s energy mix."
