The powerful duo of Sens. John McCain (R-Ariz.) and Joseph Lieberman (D-Conn.) called for a plan on Friday to require power plants in the U.S. to reduce their greenhouse gas emissions. They said the U.S.’s absence from the Kyoto treaty on climate change could hurt American industry, as well as the environment. Meanwhile, White House Chief of Staff Andrew Card said yesterday that the Bush administration probably would come to the next international climate change conference with actual proposals for fighting global warming. Last month, U.S. Secretary of State Colin Powell said the same. But U.S. EPA Administrator Christie Todd Whitman and U.S. National Security Adviser Condoleezza Rice later contradicted him, telling reporters that a climate change plan wasn’t in the cards for the conference this fall in Morocco.
