How green is Leonardo DiCaprio?

The staunch environmentalist, 33, just bought a luxe eco-friendly New York City pad, according to New York magazine. (The price is unknown.)

Called the Riverhouse, the 264-unit condominium high-rise comes complete with programmable thermostats, a 24-hour fresh-filtered air system, a gray and black water treatment facility, rooftop green landscaping and free bike storage.

The building was built with only non-pollutant materials and solar-powered energy.

Good news if DiCaprio and girlfriend Bar Refaeli decide to start a family.

The building offers a children's playroom, indoor 50' lap pool, media café, fitness center (with yoga studio), indoor children’s Light House, landscaped Riverhouse terrace and a dog spa.

His rep confirmed the purchase, telling New York, “Riverhouse is a prime example of how green technology is both accessible and achievable for new residential developments — it is a groundbreaking building.”

DiCaprio is currently in Boston filming Martin Scorsese's Shutter Island with Michelle Williams.
