WASHINGTON, May 12 /PRNewswire-USNewswire/ -- While senators John Kerry (D-MA) and Joe Lieberman (I-CT) should be commended for their tireless efforts on climate and energy legislation, several flaws in their proposal will prevent it from reducing carbon dioxide to levels that are safe and sustainable, the Price Carbon Campaign said in a statement today. "The Kerry-Lieberman bill fails the acid test of climate legislation, which is to provide clear signals on emission prices.

A group of 85 evangelical Christian leaders on Wednesday backed legislation opposed by the White House to reduce carbon dioxide emissions, kicking off a campaign to mobilize religious conservatives to combat global warming.
