The big picture: Why so few buildings are responsible for so much pollution

Of nearly a million buildings in New York City, just 2% are responsible for half of the city's building-related CO2 emissions. And, according to a new report released to the Huffington Post today by the Climate Works For All coalition, the biggest culprits are swanky luxury buildings, like those owned by the Trumps and Kushners.

The big picture: Buildings account for nearly 40% of climate emissions in the U.S., making them a prime target for improving their energy efficiency. And, with so few buildings accounting for such a large chunk of these emissions, that's exactly what a coalition of environmental groups in New York is trying to do. They're also hoping their efforts will help lay a roadmap for other cities.
