NEW YORK (AP) — Alec Baldwin says he is passionate about green energy. And he's hoping next week's United Nations climate summit brings home to Americans that the United States has fallen behind other countries in promoting wind and solar power.

Baldwin spoke at a reception Thursday night to celebrate the launch of a book entitled "Addressing Climate Change," whose contributors include U.N. Secretary-General Ban Ki-moon and U.N. climate chief Chrisitiana Figueres.

"We've been talking about this for 25 years," Baldwin said. "We need to learn the lessons that other people are learning — no nukes, less coal ... reduce, reduce, not eliminate."

Baldwin says he can't attend the climate summit Ban is hosting next Tuesday because he will be flying to London to start filming "Mission Impossible Part 5" with Tom Cruise.
