Lexus, traditionally known to manufacture luxurious yet gas guzzling sedans, has lately been getting in on the green scene by unveiling vehicles with increasingly more environmentally friendly features such as their full hybrid LS600hL.

Perhaps it makes sense that they’ve been hosting “The Darker Side of Green” debates to highlight their latest eco-friendly mode of transportation (the latest car in the spotlight is the CT 200h).

In addition to filling a niche for luxury hybrid vehicles, the company continues to hold diverse forums/promotional showcases that feature an unlikely collection of celebrities such as Sarah Silverman moderating lively chats between eco-supporters and climate change deniers.

There are 4 new debates slated to occur — hit the jump to check out all the players.

• Thursday, July 8 in Los Angeles, California: SNL comedian Andy Samberg will moderate the discussion between Mine Your Own Business filmmaker Phelim McAleer and founder of the Sundance Channel’s “The Green”, Simran Sethi.
• Tuesday, July 20 in Miami, Florida: Film actor and comedian Jamie Kennedy will moderate the exchange of prolific author/climate policy skeptic Christopher Horner and Power Trip author Amanda Little.
• Tuesday, July 27 in New York City: 30 Rock cast member Tracey Morgan will moderate the discussion between Rolling Stone executive editor Eric Bates and leading global warming skeptic/former policy advisor to U.K. Prime Minister Margaret Thatcher, The Viscount Monckton of Brenchley (aka Lord Monckton)
• Thursday, August 5 in Chicago: Former Sugar Ray singer and TV host Mark McGrath will do the honors via Grist staff writer David Roberts and the manager of American Solutions’ policy research, Steve Everley.

If the celeb-utainment factor isn’t enough to draw you or Andy Samberg’s promise that “I don’t wanna say I EXPECT it to turn ugly, but if it did, I’m not gonna break it up,” then the diverse lineup of eco-stimulation surely will — take a look at what went down when Sarah Silverman took the reins during Lexus’ March 30 debate.
