Among environmentalists, support for the bill varies. Some denounce it for doing less to curb greenhouse gases than was once promised. It aims to cut emissions by 17% below the level in 2005 by 2020, instead of 20%. Greenpeace’s American arm says it cannot support the bill in its current state. Other greens reckon that if this is the strongest bill that can pass, the best idea is to pass it now and tighten it later.
