From Ace of Spades:
"In a campaign that has spread like wildfire across the Internet, a group of Israeli environmentalists is encouraging Jews around the world to light at least one less candle this Hanukka to help the environment.
The founders of the Green Hanukkia campaign found that every candle that burns completely produces 15 grams of carbon dioxide. If an estimated one million Israeli households light for eight days, they said, it would do significant damage to the atmosphere.
"United Torah Judaism MK Avraham Ravitz called the environmentalists "crazy people who are playing with the minds of innocent Jewish people." He said the campaign would only convince people who do not light candles anyway.
"They should encourage people to light one less cigarette instead," Ravitz said."
